### Human: Safe Torque Off monitoring with redundant output Summary: I am using a PF755 w/ STO option and want to maintain a Safety Category 3. The STO board's inputs are SP+ and SE+. In Logix 5000 I am planning on using the redundant output instruction (1734-OB8S) w/ one output going to SP+ and the other going to SE+ and the Hardware Enable at TB1-1. The manual says that there is not a monitoring contact w/ the STO. Do i need a monitoring contact for use with the Feedback 1 and Feedback 2 to maintain Safety Catagory 3? If not, should i use anything on FB1 and FB2? ### Assistant: It depends on whether or not you have your PF755 connected to the Logix platform to use CIP motion or if it is connected as a regular drive. In CIP motion, you are not permitted to use any of the drive I/O cards. As a regular drive, you are. You could then task one of the outputs to be the monitoring contact. I agree with you, Rockwell made a mistake not putting the monitoring contact on the STO card. \n


### Human: Bulletin 160 to PF 525 Conversion Summary: Is there a guide for converting from an older drive? I have several Bulletin 160 drives that communicate over DeviceNet. I'd like to replace these with the PowerFlex 525 using the adapter plate. My question is on converting the ControlLogix program and the mapping. Is there a guide that would show how to remap all the DeviceNet tags, or is this something that would have to be done differently for each application? ### Assistant: You can download the publication pflex-ap010a-en-p here from Rockwell's Literature Library: http://search.rockwellautomation.com/search?q=pflex-ap010&client=literature&filter=0&ie=UTF-8&oe=UTF-8&output=xml_no_dtd&proxystylesheet=literature&site=literature&getfields=*&lang=en&hl=en&num=20&requiredfields=xlanguage%3AMU%7Cxlanguage%3AEN The main issue is the configuration of the input and output assemblies for the Bul 160. If they were configured as 103 on the input and output side like the 1305 and 1336 Plus drives then the bits line up fairly well. The speed referenced and speed feedback have to be scaled accordingly. See chapter 3. If the 160 used other assemblies then there will be more work to be done. \n


### Human: PF525 EMC Filter - Internal vs External Is there a performance difference between the EMC Internal Filter vs the EMC External Filter? ### Assistant: Hi , Best performance is achieved by using a filtered drive and the appropriate external EMC filter. EMC filters reduce the transfer of electromagnetic noise between the drive and mains power supply. PF525 drives are fitted as standard with an internal EMC filter (240V , 480V) and for most industrial applications, this will be sufficient. In the event that a higher level of filtering is desired or required, the external EMC filter can be added to either a drive which already has the internal EMC filter, or a drive without EMC filter. Most electronic equipment will generate electrical noise, small unwanted disturbances which may be conducted back onto the mains power supply. Drives basically designed to minimise this noise transfer, and offer high levels of Electro Magnetic Compatibility. Where required, additional (External) EMC Filters may be added to further reduce the level of noise transferred back to the mains power supply, reducing the risk of other equipment being affected. however where highly sensitive equipment is used, or a reduction in the electrical noise is required, these External EMC filters can be fitted in line with the drive to reduce the conducted noise emission. *****Welcome your suggestions***** \n


### Human: PowerFlex DC line voltage operation ranges Summary: Can the PFDC bridge operate with line voltages other than given in specs We have many situations in the elevator industry where the armature voltage of a given machine is above 240, and below 500 vdc. An example is one I am working on now where the armature voltage is 315 vdc. The existing machine is operating with an AB1395 drive, and it is fed by power from an isolation transformer with a secondary of 315 vac. This is a common practice, to help optimize form factor, and to help in sizing the transformer. So my question is, can I now use a PFDC drive with the same line voltage feeding the SCR bridge? There is no information in the literature. ### Assistant: Technical document for the PF-DC http://literature.rockwellautomation.com/idc/groups/literature/documents/td/20p-td001_-en-p.pdf What I see in this document is that your 315VDC motors fall in a hole for the Rockwell PF-DC products. This is DEFINITELY a time you should call Rockwell Tech Support and talk with the drives group: Dial 440-646-3434 Option 3 for Tech Support Option 1 for Direct Dial Option 1 to enter code Code 511 for DC Drives \n


### Human: Powerflex 70 Fault 08 on power up I just replaced a drive with one from my stock. As soon as I power up the drive I get F08 'Heat Sink Over Temp'. If I look at parameter 218 it shows -19 degree. Drive is not in a cold enviroment and the ambient temperature is about 22C. ### Assistant: It's a broken wire on the temperature sensor that goes back to the heat sink, or it's a failing main control board. I've had this problem on a PowerFlex 700 after it had been disassembled for repair. The wire harnesses are well built and have good latching connectors but they can still be damaged. \n


### Human: IAM Kinetix power size Summary: How to determined the IAM size? I have two questions about the IAM power size. The IAM power size depends from the servomotor size that is connected to the IAM? or, The IAM power size depends from the drives size are connected in the same rack? ### Assistant: The answer to your question is, BOTH! The best possible way to size Rockwell servo drive products is to download and install Motion Analyser. Give it enough information about the process which you are applying the hardware and you'll get very good and reliable results. One tricky spot is deciding if the multiple axes in the rack will be operating at the same time or in a coordinated manner. Rockwell's default selection for this question is NO, which means the IAM will be sized to the smallest possible load and give an artificially small overall power available. Be careful to set this choice properly so the IAM is sized to the rack properly. This goes towards your second question. If the axes are uncoordinated and do not all operate at the same time, then the individual axis size will likely drive the size of the IAM, (your first question). Proper sizing of this module is a balancing act. It is conceivable that you could end up with an IAM that is rather larger than you need for the individual axis attached to the drive because you need the larger overall power for the entire rack. Does that answer your question adequately? I DO strongly recommend using Motion Analyser. It's a free download and is really quite an excellent software tool. I'm NOT an employee of Rockwell Automation so this is not a sales pitch. \n


### Human: DriveLogix Axis Summary: Number of Axis used with DriveLogix Hi people, im planning build a machine with two axis and i was thinking to use one PF700S with Drivelogix to handle Axis1 and a second PF700S to handle Axis2 but i'm not sure if Drivelogix can be configured with two axis. Im trying to find something in manual but if anyone can help i will appreaciate very much ### Assistant: It can be done, but you're on the trailing edge of technology going that route. Have you considered an inexpensive 1769-L18ERM processor and two PF755 drives? I'm pretty sure the PF755 drives are less expensive and going the CompactLogix route offers so much more flexibility. The 1769-L18ERM is a 2-axis CIP motion capable processor. \n


### Human: MAM instruction 'stuck'??? Had a weird one at a customer site yesterday (about 4000 miles away from where I'm sitting unfortunately). Machine hasControlLogix, lots of servos & motion control. One particular axis would not move from one particular MAM instruction. Other MAM instructions on the same axis worked fine. The one which wasn't working had it's EN output set and all other outputs clear. Toggling the rung-in condition made no difference to the instruction or its outputs, it just wouldn't do anything. Other MAM instructions in the same routine operating on the same axis with exactly the same parameters worked fine. In desperation I got them to upload/download and it was then OK. Anyone had anything like this happen? It smells like a ControlLogix bug. Mike ### Assistant: Digging back in time I see that I've come across this before (different machine - one I was programming unlike the one I was trying to support yesterday). I actually raised it as a case with Rockwell and got this answer: Before you execute a MAM instruction, put an interlocking tag in there indicating the Axis_Servo_Drive.ServoActionStatus Boolean is a 1. Are you sure no other instruction may not be completed before the MAM is executed in the program? The instructions 'hang up' like this sometimes because during the scan when the rung is true, the axis cannot complete the instruction to be true. In otherwords, the .EN will stay true until the process of enabling the instruction is complete and the rung goes false. Thank goodness I keep my emails! Mike \n


### Human: Power flex 40 Summary: Communication with RsLogix5000 or Drive Executive Dear all, Please let me know how to communicate with PowerFlex40 & RsLogix5000/Drive Exicutive. As i was not able to assign an IP address to the drive. Please assit with the basic. Thanks & Regards, Mihir ### Assistant: If you only have the PF40 then you only have the DSI port that looks like an RJ45 which is not ethernet. You will need to have the 22-COMM-E card. \n


### Human: Powerflex 40P Summary: motor burning up On a new conveyor line at the factory where I've been working a motor powered by a Powerflex 40P keeps burning out. I'm no motor expert but from what I can tell looking at the windings, I suspect that the motors have been subject to single phasing. The reports on the motor are that it will be running fine and suddenly heat up, smoke and die. I suspect a bad wire in the motor branch circuit or a loose connection between the drive and the motor - the disconnect was replaced thinking it might be a bad disconnect switch contact but it didn't solve the problem. I;m wondering if there is any fault that should occur on the drive quickly upon a single phase condition. I'd expect the overload fault to occur from the increased current on the remaining phases but I don't know for sure. I know that there are phase to ground and phase to phase short faults but what if it is a broken wire in the circuit? Thanks in advance for any comments, David Butler ### Assistant: What is the cable distance between the PF40P and the motor? If it is more than 40 feet, you may be experiencing reflective wave that will punch holes in the insulation of the motor and cause it to fail. It all depends on the insulation quality of the motor you are using. A motor that is rated for inverter duty that meets NEMA MG1 part 31 would provide protection from this problem. There are also output reactors or filters available to help in the situation. \n


### Human: 22-comm-P with a Powerflex40 Summary: Communications issues between comm card and drive We have experienced three seperate powerflex 40 drives having issues with what appears to be comm card to drive communications issues. Drive performance will become erratic, MOD light on comm card will start intermittently flashing green. Communications on Profibus side have been monitored and found to be stable. When I connect my 22 comm cable to the drive to use drive explorer, the drive will go completely crazy. Once I get drive explorer connected and go to comm card diagnostics, the logic command signals come and go. Found that cycling power on comm card will clear issue so this appears to be simply restarting the communications on the 485 side between card and drive. Has anyone else seen similar issues? ### Assistant: I have seen some problems with PF 40 drives with 22-COMM-E adapters. The connection between the comm adapter and the drive stops communicating. Replacing the drive with another will fix the issue and the original PF 40 seems to work otherwise. I have not been able to determine a resolution yet. This is not wide spread but I have seen it in more than one location. Eastman do you happen to work in the Kingsport plant? Thanks \n


### Human: MPL-A1520U-EJ72AA minimum speed Hi, I just ordered a MPL-A1520U-EJ72AA. I am just trying to document the speed ranges for the machine that I am going to be using it in. Looking in Publication GMC-TD001E-EN-P - February 2014 (Kinetix Rotary Motion Specifications), I can see the max speed listed as 7000 rpm but I do not see any mention of a minimum recommended speed. Can anyone tell me if there is a minimum recommended speed for these motors and if so, where I can find this info? Thanks in advance, Paul ### Assistant: There is no minimum speed - if the motor is connected to a servo drive and the system is tuned reasonably well, when you turn the drive on the motor will hold position with zero speed. You should then be able to run it as slow as you wish. It may jitter slightly if you're asking for miniscule fractions of a rotation per second. \n


### Human: If an axis has a hard overtravel fault but the machine is in its normal working range. What could be... Summary: If an axis has a hard overtravel fault but the machine is in its normal working range. What could be one problem? If an axis has a hard overtravel fault but the machine is in its normal working range. What could be one problem? ### Assistant: The limit switch is not connected - broken wire or something similar. The drive requires a Normally Closed (NC) contact, but the limit switch is wired Normally Open (NO) That's two. It would help if you gave more information, such as drive model number. \n


### Human: Why doesn’t the top of an AM have the connectors for incoming power and contactor enable? Summary: Why doesn’t the top of an AM have the connectors for incoming power and contactor enable? Why doesn’t the top of an AM have the connectors for incoming power and contactor enable? ### Assistant: Because the first module in the Kinetix rail, the Integrated Axis Module (IAM) has those connectors. The Axis Modules use the DC bus from the Kinetix mounting plate, and don't need their own incoming AC power or contactor. \n


### Human: Disconnecting Feedback & Power Cables on Kinetix 6500 Drive Is it okay to disconnect feedback and power cables on the 6500 Drive while the drive is powered on but inhibited or safe torque off state? ### Assistant: Rockwell does not recommend it, but it is often done while troubleshooting problems. You will cause a number of obvious faults (such as loss of feedback). \n


### Human: Reset all parameters, Power Flex 4 Hello, I need to restore the entire drive (all parameters) to as manufactured. The drive code is: 22A-A4P5N104 Thank you. ### Assistant: Hi There, Have a look at Parameter P041, on page 3-12 of the user manual. http://literature.rockwellautomation.com/idc/groups/literature/documents/um/22a-um001_-en-e.pdf Cheers. \n


### Human: Need helping sizing drive Summary: I'm in need of help sizing a motor and drive. I may be incorrectly using Motion Analyzer software. I’m attempting to size a motor and drive for an application I’m working on. It involves winding paper at maximum tensions of 15lbs at a max speed of 50 feet per minute. That would be considered worst case scenario. I’m using the Motion Analyzer software and am having a hard time deciding on motor and drive. From the load alone, the calculated horse power needed to keep a tension of 15 lbs and 50 fpm is .0227 horse power. It would be ideal to run this at 120V. However, when I’m putting in these parameters to motion analyzer, I’m getting barely any solutions found. The solutions that I do find are not very good either. For example, the one solution offered to me gave me a 6.4 KW motor with a 3 KW drive. Now, why would I need such a large motor when working with only .0227 horse power? Would this have anything to do with trying to use the drives and motors at 120V? I realize this would require a larger current. Is it possible that only more powerful motors/drives are able to handle increase current levels? Or is it likely that I’m modeling my application incorrectly? ### Assistant: If you're using Motion Analyser, could you share the file here? \n


### Human: PF 753 FV mode Fwd Rev speeds not same Summary: Forward and reverse speeds do not match for same POT setting I am using a PF 753 in FV mode. Speed and Torque references provided through potentiometers. Motor runs fine up to 60hz in fwd but only about 36hz in rev. Any ideas why? I am considering reversing contactors to facilitate direction change. ### Assistant: if you have a DNO file from DriveExecutive or CCW, can you upload it? \n


### Human: PF400: Motor Overload Tripping Problem. Hi all, I am facing one problem in PF 400 drive while setting P033 [Motor OL Current] parameter. I want drive to be tripped on 220 Amp. As per manual the drive will fault on an F7 Motor Overload if the value of this parameter P033 [Motor OL Current] is exceeded by 150% for 60 seconds. So I set there 146 Amp. drive get tripped in 30 sec and actual current draw by motor is 220 Amp. But when I set 170 Amp again drive get tripped in 60 sec and actual current draw by motor is 220 Amp. Also when I set 190 Amp again drive get tripped in 120 sec and actual current draw by motor is 220 Amp. and so on..... I just want to know what should I enter in P033 to get exact overload tripping. And as per manual it should be trip on 150% of the value entered in P033. Manual is attached for reference. Any Suggestion?? ### Assistant: Hi there, I believe that the manual has a misprint. I have never known the PF400 to have any more than 110% for 1 minute overload capability. If you look at page two of the attached profile (http://literature.rockwellautomation.com/idc/groups/literature/documents/pp/22c-pp001_-en-p.pdf) you will see what I just stated. This drive was never designed for anything more heavy duty than a centrifugal Pump or Fan application. As for what the manual states, if you have a look at the PF4, 40, or 40P it states the exact same think as what you posted in your manual, so I'm guessing it was just a case of copy & paste with someone who didn't understand that this drive was different from the rest. Have a good one. \n


### Human: Powerflex 525 positioning with encoder option board Summary: Using Powerflex 525 with optional encoder board and positioning over Ethernet communication Has anybody used a Powerflex 525 with and incremental encoder and encoder option board for a positioning application. The Powerflex 525 will also have the dual port Ethernet comm card (E2P) and be on a Device level Ring. I am using RSlogix 5000 V20.03 for programming. The application we will be using this for will have maybe 3-5 positions to goto and will be manually homed. ### Assistant: I've not used PF525, but have done what you describe with PF755. In the PLC program, they're going to look identical. There are several pitfalls you can avoid. First, though it is documented it is easy to miss the fact that your coarse update time setting in the Motion Group Properties MUST be set higher than 3 milliseconds. The default value is 2 and that will just not work. I've found that even 3 milliseconds is sometimes not large enough. For two axes, we've been setting the Coarse Update time to 8 milliseconds. Next - before you add motor nameplate data or adjust any maximum velocity, tuning, or customize ANYTHING in the axis, you must, Must, MUST make sure the firmware is up to date in the drive entry in the I/O tree. If you change the major firmware setting, if you change the slot in which the encoder card sits, if you do almost ANYTHING in the drive entry in the I/O tree, Logix says that all your careful work setting up the axis in the motion group will be set back to defaults. This has bit me in the ass often (as you can tell from the capitalized words for emphasis). If you have to upgrade the firmware in the drive, you're screwed regardless. Keep daily copies of your program so that when (not if) you have to do a firmware upgrade, you have a reference to what all the settings in the axis were. You're welcome to contact me if you need additional help. \n


### Human: Powerflex 755 Drive faults Summary: Precharge, Alarm 14, + some questions Hi, I'm having a few problems with two of these drives and I would like to just confirm some things with someone who isn't guessing. Im fairly new to the drive and job so im still trying to figure things out Why would the DC bus voltage be up, but not show the DC voltage up status? Why would the drive have power on the 3phase incoming, but the DC voltage remain down until you send a reset signal to the drive? I have seen Alarm 14 which is ground fault, I think this may be my actual overall problem, but I want to ensure I have everything covered before telling the customer his ground is rubbish, it’s a large reputable site, however saying that, it is based in china Why would the drive sit in pre charge and require a reboot to run again? I have read through some manuals, and I think it might be down to the PWM exceeding 125% of my line to line voltage dropping out disabling the precharge for the drive, however sleep has been a problem lately, and im at wits end, so I may just be seeing the words I want to see to blame the ground When should you take the enable signal off the drive? If the drive was being given a motion command while the enable was dropped could I we be causing problems? And in turn, a motion command before the enable is active Should we be dropping the 3 phase power to the drive roughly twice every 10 minutes? If we drop the 3 phase voltage is there a minimum time before we should re apply it? Any help would be greatly appreciated Thanks ### Assistant: Page 13 of the programming manual (I have revision I, July 2013 handy) and page 13 of the reference manual (September 2013) says you should power-cycle the drive no more than one cycle a minute. That said, if you are using an input contactor to drop line-in AC power to the drive, you should consider using a safe-torque-off option card. This uses 24VDC signals to disable the output stage of the drive so you do not have to constantly cycle line-in power. You need to attend to the ground warning alarm 14 before anything else. Having significant current being measured to ground means there are real wiring problems. The ground conductor coming back from the motor should be landed on the drive PE terminals and no where else. Landing it on the back panel or on a grounding lug separate from the drive could be one cause of this. What size drive is this? What line-in voltage? \n


### Human: Kinetix 300 for web tension control Summary: K300 in analog velocity mode following +-10VDC signal from tension controller; advise please Hi, I am using a Kinetix 300 Servo Drive (2097-V33PR3) with a MPL-A1520U-EJ72AA servo motor in a web tension control application as a driven unwind. I am operating the K300 in analog velocity mode, where the speed of the servo follows a -10 to +10 VDC signal from a closed loop tension controller. The tension controller allows the operator to enter a tension set point and monitors feedback from a tension transducer roll that is mounted in my web path. Based on the entered set point and the feedback from the tension transducer roll, the tension controller uses a PID loop to regulate the -10 to +10 VDC signal to run the servo at just the right speed to create the desired tension. This is the first time I have used a servo for this purpose, and I am trying to get my tuning as good as I possibly can. As far as the servo is concerned, I just followed the tuning instructions (Tune the Axis) in the Kinetix 300 User Manual (2097-UM001D-EN-P). I tuned the servo with my unwind shaft empty (no spool of material in place). The tuning procedure completed with success almost immediately (I didn’t even see the motor turn). It came up with the following settings: Velocity P-Gain = 15137.504, Velocity I-Gain = 3558.289, and Gain scaling = -9. After doing this, I threaded a web and tested my tension control with the K300 controlled by my tension controller. The default PID settings in the tension controller seemed to be too aggressive and caused the servo to oscillate even at zero web speed. I played with these settings to make the tension controller PID loop less aggressive until I was able to maintain tension at set point a zero web speed with no oscillation on the servo. After doing this, I started running web at different speeds throughout my required range, and I was quite happy with my tension control. It’s not perfect, but I have some mechanical and other issues on my test machine that I believe to be creating some transients in my signal from the tension transducer roll. I have a feeling that these issues will impose a limitation on how good I’ll be able to get this working on this test machine, but I am hoping to learn as much as I can in my own shop before I ship these components to my customer and try to get it working in the field. (At my customer, I do not expect to have the same issues I have with my test machine, so I expect to be able to get much better results there). I was just wondering if anyone here has done this sort of thing with a K300? I was just wondering if you basically used default settings in the K300 and did a standard tuning with an empty shaft like I did? Or did you find it helpful to change any settings in the K300? Or do you think I should have done the tuning procedure with a spool of material in place (so that there would be more of a load?) Any advice you can give me would be greatly appreciated. thanks in advance, Paul ### Assistant: Paul, I suggest repeating your tuning process with a load on the shaft. I also suggest you look at the values used to tune the axis - make sure you have them such that the axis does in fact move (torque and velocity limits high enough, position limit large enough to permit motion). The autotune usually has a small but noticeable motion. \n


### Human: PowerFlex DC Interposing Relay Summary: Recommendations for Interposing Relay on Frame C drive? Customer says tech support said an interposing replay for the main contactor on a Frame C drive would help with contactor faults. KB document 32187 indicates that we don't recommend an interposing relay for a 100C contactor. The customer didn't have any information sent by tech support. Do we, or don't we, recommend an interposing relay for a Frame C drive? If we do, what kind of relay and is there a wiring diagram? ### Assistant: You can install a 50 mF capacitor between the digital output driving the main contactor and common to fix this issue. There is a tech note out there but I do not have it handy. \n

### Human: How can I see if my encoder is working via the HIM? Summary: Verify encoder operation Hi, Can I use my HIM on my Powerflex 700 to see if my encoder is working? Mainly I want this for troubleshooting purposes to see if the encoder is sending a signal to the drive. A local service tech troubleshot the problem for us. I'd like to be able to do this myself using the HIM to save a service call. I do not have access to any software that I can use to connect to the drive. (What would I use for this) As you may have guessed, I haven't worked on drives before, so any help is welcome. Thanks, Bill ### Assistant: 1. what type of encoder is it 2. what family of plc are you using and what hmi do you have 3. what is the comm format between between your plc and hmi 4. Do you have access to an Occiliscope, this may be easier to hook up and troubleshoot. \n

### Human: CIP Motion + Drive Firmware Update = Extreme Aggravation Summary: Updating the firmware on a PF 755 drive used in CIP motion isn't worth the effort, but you HAVE to because of the bugs When you upgrade the firmware in a PF755 used in CIP motion in a Logix 5000 application, the drive definition in the IO tree also needs to be changed to match. However, when you do this, many parameters which you painstakingly set for perfect operation get wiped or reset to defaults. Your drive tuning values? Gone. The motor nameplate data that you entered? GONE. You're looking at about 15 minutes PER drive of careful parameter verification, IF you were smart enough to keep an old copy of the program with which to compare. This is not only irritating and stupid, it's the behavior of a saboteur. Rockwell, why on earth would you wipe out the motor nameplate data just because I changed the firmware revision level within the drive definition? Do any readers know of a way to simply transfer the parameters from an old program to a newer one to alleviate this problem? ### Assistant: It's a year later, and this is still a problem. I reused a program written last year, with drives at firmware 7.1. I had to upgrade the setting in the program, and it wiped out the same information. After going through that exercise, I discovered my shop had put encoder cards in a different slot than expected. That seems like a simple change in the software, right? Change the slot number on the pull-down? NOPE. Doing that causes Logix5000 to wipe your data. This nuclear option has to change, Rockwell. There is no good reason for this behavior. \n


### Human: Where can I find the documents about the configuration for PF755 Point to Point application My system is a lifter controlled by PF755. In this system, there is one 20-750-ENC-1 on VFD port 4 and one 20-750_UFB-1 on VFD port 5. First, I configure 'Port 4:Encoder Feedback' as velocity feedback(Parameter:125) and 'Port 5:FB0 Position' as position feedback (Parameter:135). Secondly, I configre mode to 'Psn PTP' through patameter 309~313. Some other parameters about PTP are as following 770: All zero(Default) 771: Absolute(Default) 772: It's conncet to one DOP bit from DeviceLogix. It will be true when VFD recieve move command from PLC. 775: Port 0: PTP Setpoint (Parameter 780). Parameter 780 is associated to Datalink 1 which is the target position from PLC. When I try to raise the lifter, it cannot reach the target position. 'PTP Setpoint'(780) is right, it's the same to the tartget position from PLC. But 'PTP Command'(784) is less than the target position. And I saw the motor is running forward and reverse continually. Later, VFD will result in fault 64(drive overload). I don't know what's the problem. Maybe there are some parameters are not configured OK now. Where can I find some reference documents for it. Thanks. ### Assistant: Ensure that upon starting the application Parameter 780, PTP Setpoint, is equal to Parameter 847, Position Feedback. If this is not the case, the PTP Command will always be offset by the difference between Position Feedback and PTP Setpoint.

### Human: Local and Remote HIMs not booting Summary: A pair of Enhanced HIMs will not boot on powerup with PF70 I went around the block all day on this one. I ended up with a less than optimal solution. What I have is a 2HP Powerflex 70 in Frame B. I wanted to put a 20-HIM-A6 in the local Port 1 slot and a 20-HIM-C6S remotely. These are both Enhanced HIM devices. They refused to boot - backlights come on, but no boot. If I remove either HIM the other will boot and I can reinstall the removed device and it will boot, as well. All devices communicate when they are booted. Why will these two not boot on powerup? I can get an A3 and the C6S to boot properly, but I really wanted the A6 in the Local Slot. Ideas? ### Assistant: What firmware are the HIMs? We've discovered a bug with firmware 2.003 for A6 HIMs in that they will not scroll if more than 3 items are to be displayed. I wonder if you have discovered another firmware problem. For that matter, what is the firmware of the drive? Is it up to date? \n


### Human: Powerflex DC HIM Copycat - Firmware Revisions Summary: Can a parameter set from older firmware be loaded into a drive with a more recent firmware? I'm new to RA Drives and this question came up. If you have a HIM for the Powerflex DC with a set of parameters stored on it. After a customer has failure on the drive and installs a newer drive with an updated firmware version. Will the HIM correctly download the parameters into the newer drive with the updated firmware without errors? Thanks ### Assistant: nan \n


### Human: frequent failure of IGBTon PF700s frame 5 & 6 Summary: frequent failure of IGBT resulting to multiple downtime Hi, We are experiencing frequent (10x different controller) IGBT failure on powerflex700s frame 5 & 6 (20DR096A0ENNANASE & 20DR248A0ENNANASE). Supplier recommended to install voltage conditioner and yet failure continues, resulting to frequent shutdown of our paper machine (happens on paper dryer section). Loads are at 60% only. Thank you in advance. ### Assistant: https://rockwellautomation.custhelp.com/app/answers/detail/a_id/17254 The article above is somewhat flawed - it should have a schematic diagram image with it but does not. Still, it points to one possible scenario - the snubber resistors have failed. You've given us very little information with which to assist you. When the drives failed, did you replace the entire drive, or just the portion that failed? What sort of voltage conditioner did you install? Do you have an output contactor between the drive and the motor? Does the enclosure containing the drive have sufficient cooling? Much as one would like to point a finger at the drive as being a bad design, the PF700S is one of the best Rockwell has ever offered. There are MANY of these drives operating today. It's most likely that there is something about your particular application causing the failures, especially on two different frame sizes. The more information you can give us, the more likely we'll be able to help you solve the problem. \n


### Human: Power Flex 4, Manual Start Summary: Manual start to check engine Hi, I need to know how to do force to start the engine connected to the unit. Can it be done by the panel potentiometer? ### Assistant: Potentiometers would give an analog speed signal only. You will need to wire/configure your PF4 to start automatically from an input or from the red/green off/on buttons on the drive itself, if I understand your question. The information for configuring and wiring the drive is in the installation manual. \n


### Human: Question about motor driver information Summary: location for storing motor driver info Hi all, I have questions on motion control. Q1. what are the motor driver information? And what it means when people say 'putting all motor driver info on the PLC and have an auto download of driver info once an new driver is installed'? Please help me in details because I don't know much about motion control and PLC ( I am fresh in auto) Q2. what it means when people say 'put recipe system and info on the PLC and not on the HMI'? Thanks! ### Assistant: The PLCs that support CIP motion and control Powerflex 755 VFDs download all data to the drive on power-up and successful network connection. When a drive is used outside of CIP motion, basic motor data is not usually sent to the drive from the PLC. In fact, the minimum control one could do over Ethernet for a drive not used for CIP motion is a start/stop command and a speed reference. All other parameters (tuning gains, motor data, etc.) would have to be set at the drive. Additionally, Rockwell's recent versions of PLCs can store the firmware of a drive (regardless of CIP motion or not). With the proper configuration in the PLC, this firmware can be downloaded to a drive automatically to a new drive replacing a failed one. \n


### Human: Axis Gearing Summary: Synchronizig to Axis using MAG (Help is needed)Hi, I am using a motion axis card for controlling the cut of a flying shear.for synchronizing the line speed with shear i am going to use MAG instruction, but i don't know how to do it. How can i synchronize them in the way that when line speed goes up, shear speed goes up too. ### Assistant: does the flying shear need to hold exact position in respect to the line? If so youll need to use a MAPC to follow the line master. \n


### Human: RDD Motor Summary: Can I use PF700s to control RDD motor.Hi, I had a project which I plan to use a RDD motor but heard that this only compatible with Kinetix drive. I wanted to use PF700s which we use a lot and I wanted to know if someone here, uses this motor. I need to learn from someone who has hands-on with this motor. Thank you in advance. ### Assistant: Rockwell's Motion Analyser shows you can combine RDD motors with PF700S drives. I'd suggest using this tool to check the combination you want to use. The actual part numbers apparently use the prefix RDB, but they're talking about the family of motors RDD. \n


### Human: 755 Parameter 38 Summary: I have a 25HP drive that works best with the switching freq at 2khz. When power is cycled, it defaults to 4khz. Why? ### Assistant: What is the version of the drive? What is the voltage and amperage of the drive? What are the values of parameters 305 and 306? (Voltage Class and Duty Rating) Is this drive connected to a controller? If so, is Automatic Device Configuration (ADC) enabled for this drive? (Sorry for continuing my trend of asking more questions than providing answers.) \n


### Human: Ultraware 1.64 Install Error I am getting an error trying to install UltrWare V1.64 on a new laptop running WinXP Pro SP3. The install appears to get a significant way through the install, a window pops up very quickly and then disappears, the installer continues for a short time and then I get a pop-up window that says:A general error occurred. The Motor Configuration tool as well as the Ultraware help are installed. This install is on an IBM Thinkpad T500 with no serial port. I also don't have a comm port redirector installed. Any ideas? Keith ### Assistant: The desktop icon for Ultraware is visible until after the OK button is clicked on the error message after which it disappeared. InstallShield is rolling back the install after it encountered the error.Reinstall Ultraware to the point where the error occurred and then go to Task Manager and shutdown Installshield. The Install does not roll back and Ultraware works beautifully. [Reference Aid 68984] - fuzzy logic \n


### Human: Powerflex 523 runs at full speed I have a Powerflex 523 drive running a 1 horsepower motor. When you press the start button the motor starts but accels to 60hz, not matter where you turn the drive pot the motor does not slow down. I have the source 1 control set to keypad and speed control 1 set to drive pot. I must be missing something in the set-up. Walt ### Assistant: Hi there, What did you set parameter P043 (Min Freq) for? Do you have anything wired into terminals 03, 05 or 06, these are defaulted to Preset speeds and will over-ride anything else. Are you sure that you have P047 set to 0? If you have it set to 1, then you are set for Keypad Freq, which associates itself to Parameter A426, and that is defaulted to 60Hz. If you look at the page in Chapter 1 that references Start and Speed Reference Control (Page 46, PF520 User Manual) in the manual, it shows you the hierarchy of the control structure for the drive. \n


### Human: 2 powerflex 700,s running 2 seperate motors on the same drive chain We are getting ready to remove 2 DC drives and motors that run 1 chain and replace them with 2 PowerFlex 700 and 2 AC motors. Whats the best way to do this? ### Assistant: Heres a better explination of what we are trying to accomplish. We have a silo that has a sweep chain that runs around the outside circumference of the silo. Right now it has 2 DC motors on opposite sides of the silo that run the one sweep chain. The 2 DC motors are synced and are attached to the one sweep chain. We want to replace the DC motors with AC motors and Powerflex 700 drives. What is the best way to sync the 2 Powerflex 700 drives? \n


### Human: eplan macro for soft starter smc-3 150 Summary: looking for macroshello, I'm looking for this macro and in the website of rockwell macros for eplan I don't find this, I look motor control, drives and all the macros, where is it? thanks ### Assistant: nan \n

### Human: CIP Motion - Commissioning Summary: CIP Motion - Kinetix 6500 MP Series Electric cylinders and Linear stagesHi everyone, I'm trying to put together a plan for commissioning and testing of CIP motion - Kinetix 6500 Drives with linear actuators. MP-Series electric cylinders, MP -Series linear stages and Parker actuators. Also a few rotational applications. A total of 26 Servo axes. I've identified the following activities once the mechanical and electrical install is completed. 1.Tuning linear stages. 2.Setting any soft limits. 3.Setting peak torque/Force limits. 4. Testing homing sequences. (Some to switch, others to positional error) 5. Testing positional accuracy/repeatably. Am I missing anything, and are there any best practice guidelines? Also would be helpful for rough timing estimates to commission each servo axes. Many Thanks David. ### Assistant: You'll need to get firmware on the drives matched to version number in your I/O tree, or else set the I/O tree devices to compatible. Make sure you have the most up-to-date AOP for your hardware. You have a major task in front of you, one that could be measured in weeks. Just getting all the drives to initialize and register properly in the motion group after power-up can be a challenge. If even one axis/drive gives you problems, the whole motion group is effectively paralysed. You'll discover that if you make a change to a drive in the I/O tree, the associated axis will reset various parameters to default. In the case of accels, decels, jerks, this is value of zero. If you forget to then move them to non-zero values, when you try to move the axis you'll get an error. You then have to set the max accel, decel, jerk, and try again. Over, and over, and over. \n


### Human: Powerflex 525 via 25-COMM-E2P Summary: 25-COMM-E2P As Communiation Option Not Appearing In Hardware Selection I have a project that is using two Powerflex 525 drives, one using the embedded IP comms ports, the second using the 25-COM-E2P card to provide a pass-through capability for the IP network. Running Studio5000 V21.00, I have registered the EDS files in RSLinx (V3.6) and in Studio for the 25-COMM-E2P but the card communication option does not show up when I try to add the 525 drive which has the E2P card fitted to it. Also, the AOP files do not install. The Installer does not show any profiles that are to be installed so could this mean that the AOPs for the 525 are already installed? If so, then why doesn't the 25-COM-E2P option show up once the EDS files are installed? Any thoughts and help appreciated. Many thanks, John ### Assistant: John, not sure where you went to get the AOP. Go here: http://www.ab.com/support/abdrives/webupdate/software.html Go to the bottom left grouping, select the link second from from bottom (RSLogix 5000 Drive Add on Profiles) On the new page, select second link from the bottom again (non-cip motion), and select 520 series. If that doesn't work you might try going here instead: https://download.rockwellautomation.com/esd/download.aspx?downloadid=addonprofiles 3rd link from the top is for 525. The first one I showed you is a 343mb link. This second one, supposedly for the same thing, is an 811mb link. I have no explanation at all for that. I'm downloading both right now. I will install the smaller one first, then the larger. I'm doing that because I do not have the 525 to put into my I/O tree either (same boat as you). I will advise when I have something to report.

### Human: PowerFlex 755 Summary: Fault code 13035Hi, I got a system with ControlLogix L61(FRN 17) and PowerFlex 755 with Ethernet/IP communication. a broken powerflex 755 has FRN 1.1, and replace with a new powerflex 755 FRN 9.1 after download the drive parameter and change in IO tree at rslogix5000. at powerflex 755 i got a fault code 13035, Net idle fault. any idea/help appreciated. Thanks. ### Assistant: Raph, you've got yourself a conundrum. Firmware 1.1 is seriously buggy; the fact that you've not had problems until this point is quite lucky for you. The easiest solution in terms of amount of work is to downgrade the firmware of the drive using ControlFlash. You can download the firmware from this page: http://www.ab.com/support/abdrives/webupdate/index.html and http://compatibility.rockwellautomation.com/Pages/MultiProductDownload.aspx?catID=6&Keyword=PowerFlex&crumb=112 That leaves you with buggy firmware. However, if it's been working, I suppose you will not have future problems. I've had experience with that firmware; in your shoes I'd leave the firmware of the drive at 9 and instead install a new AOP into ControlLogix, then change the firmware listing for the drive in the I/O tree. If your application truly has been working with no problems, take the easy route and downgrade the drive firmware to match the application. \n


### Human: Kinetix 6500 going into STANBY after power cycle Summary: Kinetix 6500 going into STANBY after power cycleWe have 2 kinectix 6500 that run 2 movable conveyors. Occasionaly when one of the drives faults and we cycle the power to the drives one of the drives comes back up in STANDBY mode. The only way to fix the STANBY state is to download the program. We have the lasted firmware update. Any Ideas ### Assistant: First determine the fault and put logic into the processor to recover from the fault. The fault can be determined either from going online with the processor, clicking on the faulted axis, and then viewing the axis status in the quick view pane lower left corner of the project organizer. Or reading the fault code on the front of the drive and consulting the trouble shooting section of the manual. If it were me I would power down the panel,remove the control module, and reseat it a couple of times and see if the issue goes away. Sometimes the connections are contaminated from handling during panel build and the control module just needs to be reseated. http://literature.rockwellautomation.com/idc/groups/literature/documents/um/2094-um002_-en-p.pdf \n


### Human: Variable High Inertia Servo Tuning Summary: Kinetix6000 servo driving a variable high inertia loadThis maching was built by someone else some years ago and we're still having issues with it. I have a Controllogix motion driving a series A Kinetix6000 servo rack. My trouble component is a rotary positioning table. The servo has about 1750:1 ratio to the table and an auxiliary encoder directly reading the table. Dry table to motor ratio is about 1:1. However, max load is around 40:1. We're finding we have to change loop tuning to prevent oscillation. Most moves are either jog or index. However, I have some times where I need to electronically gear it as a slave to a vertical axis for tracking helical motions and I need to keep a solid position lock. Is there any simple method to adjust tuning to keep the dynamic similar? I'm already changing velocity and acceleration profiles in the motion function blocks on the fly based upon part data to keep current and torque limits within reach. ### Assistant: You can create code to swap gains depending on the step in your cycle. Record the necessary gains for each step, load them into an array, and then move the array values into the servo gain tags before beginning each move. \n


### Human: Powerflex 753 & Powerflex 755 interchangability Summary: Replacing a Powerflex 755 with a Powerflex 753I'm looking at setting up spares for Powerflex Drives. I plan on having 1 spare size within the frame size where it makes sense but there are also several 753 & 755 in use - mainly on overhead cranes. There does not seem to be a lot of difference between the 2 drives aside from embedded Ethernet and I am looking to investigate the possibility setting up the 753 for most - if not all - of the applications. I need to understand better why the 755 was used and what makes the 755 required. What would be the things to look for ... or the right questions to ask ... to know if a 753 could replace a 755 without problems? ### Assistant: PF755 has built-in torque-proving capability specifically for cranes. You might not need this for the bridge or trolley portion of your cranes, but it is definitely worth further research for the hoist. The PF755 is also capable of being used by a logix processor to do CIP motion. The PF755 has more option slots available than the PF753. If you do not need torque proving or integrated CIP motion, the PF753 is the less expensive choice. http://literature.rockwellautomation.com/idc/groups/literature/documents/br/750-br001_-en-p.pdf This sales brochure is a good one to compare the two drives. http://literature.rockwellautomation.com/idc/groups/literature/documents/sg/pflex-sg002_-en-p.pdf This brochure covers almost all of Rockwell's drive offering \n


### Human: Need help with Rotary Knife application Summary: Cam and Motion control Hello. I have to start up an application for the paper industry that basicaly cuts paper with a rotary knive. As hardware I have PLC 1769-L27ERM-QBFC1B, HMI PVW600 Compact, Switch Stratix 2000 and 2 PowerFlex 755 with encoder card 20-750-ENC-1. The movement has to be made with some sort of a E-CAM between the main supply engine and the rotating knife, but I don´t know how to configure the CAM. Can anyone help me with this? All I need is an example, because I don´t know wher to start. I have all the motor data, the ratio, etc...but I don´t know how to use this data.... ### Assistant: A good place to start is the drives accelerator toolkit. The MCCP and MAPC instructions are sophisticated and it will take a LOT of time to answer questions via forum messages like this. http://www.emea.rockwellautomation.com/oem/en/misc/free_design_tools.aspx Another place to look for assistance is your local Rockwell distributor and representative. If you have purchased the hardware, they should be very willing to help you. Even if you have not made the purchase, they should lend some assistance. If this is a class project though, a theoretical exercise, keep in mind the help you're asking for normally commands an hourly rate from a systems integrator that might surprise you. \n


### Human: Powerflex 753 with 1336 brake chopper In process of upgrading a Impact1336 to a PF753. The system currently uses a 1336 chopper for braking. Can I reuse this or do I have to use dynamic braking through the drive. ### Assistant: You must take the chopper out of the circuit and do dynamic braking through the drive. \n


### Human: Controlling Backlash with two motors I was wondering if someone has experience in driving two motors in anti-backlash with the Allen-Bradley servo drives? The mechanism rotator has two sets of motor-gearbox drive assemblies to eliminate the anti-backlash, when the mechanism is driven under computer (Controllogix CPU) control the two motors are torque-biased against each other to remove backlash while a differential torque signal is used to produce the required movement. My idea is to use 2 servo drives Kinetix 2000 (in position and velocity loop) and a contrologix CPU. I just looking for help or ideas o any experience in this configuration setup, using the Allen-Bradley PLC and drives See an example of Kollmorgen Drives: http://www.motiontech.com.au/assets/pdf/Kollmorgen%20Rack%20Drive%20Panel%20Controlling%20Backlash%20with%20the%20Servostar%20600%20210812.pdf ### Assistant: nan \n


### Human: 2094-BM01-S Fault with no Fault Code Summary: Mystery FaultYesterday evening one of the 2094-BM01-S servo drives on a piece of equipment showed a Red Light at the Drive Status light. Looking up in the manual shows that as a drive fault and to read the fault code. The drive does not show a fault code and all the servos on the bus bar are at boot step 3. When I cycle the power the light turns off until at step 3 again then lights back up and stays at step 3. PLC software shows the drive faulted, but resetting the fault does not do anything and will not indicate what fault it is. A new drive was ordered and installed but problem continued on new drive as well. Unplugging all cables does not clear the fault nor does unplugging all the cables on the servo drives next to faulted drive mirror the issue. I am at a loss, any help or direction would be appreciated. ### Assistant: Logix/Studio 5000 should show some sort of error code for the drive on its properties dialog box. Check out these knowledgebase articles. Most talk about a firmware / software problem with one specific combination and a phase loss attribute new to that version - did something in the system get upgraded? The other possibility is that something happened with the encoder in the motor or with the motor definition in the PLC program such that it doesn't match the actual motor. Was someone in the program recently? https://rockwellautomation.custhelp.com/app/answers/detail/a_id/48500 https://rockwellautomation.custhelp.com/app/answers/detail/a_id/48895 https://rockwellautomation.custhelp.com/app/answers/detail/a_id/33524 https://rockwellautomation.custhelp.com/app/answers/detail/a_id/56938 https://rockwellautomation.custhelp.com/app/answers/detail/a_id/23802 https://rockwellautomation.custhelp.com/app/answers/detail/a_id/53546 \n


### Human: Ultra 3000 Won't communicate I have a set of Ultra3000i drives that will no longer communicate with ultraware. I have tried with my other drives to verify that the problem is not with ultraware settings. Any help would be greatly apprecieated. ### Assistant: Do you mean you are able to connect to other Ultra drives with same PC and same cable ? Did you get a comm error? Which ? Anyway, try to take a look to the following technotes.... Aid 47739 - Aid 49520 - Aid 42830 Hope this helps... - fuzzy logic \n


### Human: PowerFlex 753 with new Main Control board Summary: Having electronic keying issue Had a main board go out in a Powerflex 753. New board says it is v10.2. I can not find the database for this version and when I try to create one it never shows up? I have up to v6.11 on my laptop. Running off of a compactlogix if that makes a difference? Can set to highest and disable for the time being if it will communicate correctly, but would like to keep the keying on. Thanks, DR ### Assistant: You can use controlflash to downgrade the drive to match your application. Upgrading your application to match your drive can be be a bit time consuming. If you go to this website: http://www.ab.com/support/abdrives/webupdate/index.html You can download the latest AOP for the PF750 series. That must be installed into your version of Logix 5000. At that point, you can select the proper firmware to match the drive. However, the firmware in your application is not too troubled (unlike earlier ones) so it's ok to stay with 6.11. From the same page noted above, you can download the firmware for 6.11. Install that into the drive and you should be good to go. \n


### Human: Kinetix 6000 High registration input use I have a kinetix 6000 drive and I'm trying to use the high speed registration input (REG1), but I don't know in which tag of the axis can I monitor this input. could someone tell me where can I see the status of this input in the control logix? ### Assistant: I believe what you are looking for is AXIS.REG1INPUTSTATUS . It's also represented by AXIS.DRIVESTATUS.07 (drivestatus DINT bit 7). This information is in the Logix help file. Click the Index tab, scroll down to AXIS (below the all-lower-case axis), expand to SERVO_DRIVE structure. \n


### Human: Powerflex 755 Summary: Unbalance current inputI'm using powerflex 755 FRN 1.010 at body maker machine from stolle machinery. Now when i measure the current input R-19 amp, S-50 amp and T-50 amp with a balance voltage input R-S-T 390VAC. after changing input power cable from R to S, the current reading change R-50, S-19 and T-50. The current output and voltage was balance. But the strange thing was, when i change with another powerflex 755 in that panel, the current reading was OK. Any idea what should i check or do? Thanks. ### Assistant: Are you saying the current measurements on the second drive are balanced (50 amps each on R, S, and T)? Is the second drive also at firmware version 1.01? Are the two drives EXACTLY the same in all respects? \n


### Human: Powerflex700VC Encoder Loss Flt 91 Summary: PowerFlex700VC FLT 91 Encoder Loss FaultGood day! One of our electrical hoists is tripping from time to time with FLT 91 Encoder Loss Fault. Sometimes it happens during lifting and hoisting up/down with or without load and sometimes even without using it. The system has been working for 10 years without any issue, it just started last month. I have changed the encoder, encoder connector, encoder card and checked all the wirings interconnections but so far, no luck. The length of the encoder cable (festoon) is around 100 meters. Out of frustration I’m now planning to change the VFD and cassette control card, but I really don’t think that they are the culprit. Another thing is to change the cable, but this is a very big job. I’m lost to what I do next and in need someone expert advise. Thanks, Ian ### Assistant: I don't think this is a VFD problem. Could be cassette, but more likely I think you have a cable problem. You've changed everything else directly related to the encoder; I'd lean towards a cable conductor fracture. Before replacing the cable, can you do a close inspection of it, including tactile? One other place to look would be the power supply feeding the encoder. Do you have proper voltage all the way out at the encoder? If you're not externally powering the encoder (using the cassette), then replacing the cassette might do the trick. How often does the failure occur now, and when (or WHERE in the hoist motion) does it occur? \n


### Human: ultra 3000 sercos DriveHardFault Summary: Have problem with drive hard faults on a ultra 3000 digital servo drivewe have this fault after we power down to clean machine, sometimes it will power back up with no issue. But most of the time it requires many power off then power on to correct the DriveHardFault. any help would be appreciated. ### Assistant: This is a 2098-DSD-HV220-SE DRIVE \n


### Human: Get Coarse Update rate in CLX I want to have the value of the coarse update rate in ms or microseconds in the CLX. I checked if I could call this value by using the GSV-instructions and did not find it. I have motiongroup updated on coarse update rate and a motiontask triggered by the event of motiongroup updated. To find a good balanceon the processor CLX execution time of the (1) motiongroup update rate itself and (2) the motion task which is logic with motion instructions, I would like to have the value called by the CLX . If possible I would also like to know if I can change the coarse update rate with a SSV, to find a better balance between both points mentioned both. Regards,FV ### Assistant: I have searched what you need...It isn't available in GSV or SSV instructions and also I've not found indication about a Generic CIP message that could retrive it... it seems not possible to me :smileysad: - fuzzy logic \n


### Human: Sercos Protocol Error I am having an issue with a sercos ring randomly dropping out. The ring will get to phase 4 and then lose comms and start the cycle over again. This fault resets itself automatically, but it also stops all motion on that secros ring and causes an fast stop situation on our machine. I pulled some of the sercos log information as detailed in KB 56209 and see that I am getting a 16 ### Assistant: Can you give us a map of your SERCOS ring? What hardware? What is the processor? You say you've replaced all the drives but one, and the problem persists. Are you going to try replacing that last drive? \n


### Human: PF400 - Analog Out2 I have PF400 15kW 30A and my motor rating are 15kW 26A. I wanna use the analog output from PF400 to show the current consumption. Parameter values: P033 = 26A, T085 = setting 15 (4 mA = 0 Amps, 20 mA = 200% Drive Rated FLA) What is Drive Rated FLA? Is that the value i entered in P033 or the drive rated current? What kind of scale should i use 0-60A or 0-52A to show the correct consumption? ### Assistant: Drive FLA, is the rated current output of the VFD, so in your case it would be the 30A. So, your analog output would show values ranging from 0 - 60A without adjusting the scaling in T086. If you look at the examples in the manual for T086, you will see how adjusting the scaling will adjust the range of the output displayed. \n


### Human: 160 Drive DeviceNET interface Summary: DeviceNET interface retain settings? We have a facility in Malaysia that has several 160 drives on DeviceNET that have failed. They do not have RSNetworx, or the experience to use it if they purchased a copy. We have here a few of these drives that were pulled from older machines. We can send them spare drives, and even program a DeviceNET module if need be, and send it over there. Can they simply replace the drive and plug in the DN module? Does the DeviceNET module retain the settings like the HIM module for a 1305? ### Assistant: Few days ago, I replaced one of them (160), in order to change this device you need to make sure the EDS is the same ( older and new one), if you removed one 160, ( for example node #3 ), the new VFD need to be same node and same EDS. Hope help you. Regards \n

### Human: flashing/converting a pf525 back to a standalone drive after i have set it for multidrive Summary: i can not download to the drive to make it a standalone drive hello can you advise. I made my 525 multidrive, for a presentation, and now I can not get it back to a standalone drive. I tried studio ver 24, ccw ver 7, usb app I can not get this to work as when I start this it does not tell me what kind of file extenstion it is looking for so I can not search for the file on my pc to try and flash back from the usb app as this is the only avenue I can think of to try. current version of drive is 4.01 thanks ### Assistant: Have you looked at (from user manual): C169 [MultiDrv Sel] Sets the configuration of the drive that is in multi-drive mode. A reset or power cycle is required after selection is made. Options 0 “Disabled” (Default) No multi-drive master from the internal network option module or embedded Ethernet port. The drive can still function as a multi-drive slave or as a single drive (no multi-drive used). 1 “Network Opt” Multi-drive is enabled with the internal network option as a multi-drive master. The host drive is “Drive 0” and up to four slave drives can be daisy-chained from its RS485 port. 2 “EtherNet/IP”(1) Multi-drive is enabled with the embedded Ethernet port as the multi-drive master. The host drive is “Drive 0” and up to four slave drives can be daisy-chained from its RS485 port. (1) Setting is specific to PowerFlex 525 drives only. Not sure if that will help. \n


### Human: POWERFLEX DC 3000 - Field Volatge Summary: Field Voltage VariationI am using the Motor with Field Voltage of 195 VDC. But my drive is giving 207 VDC. I am supplying 220 VAC to field supply. Can anyone suggest how to reduce or amend the field voltage as per the motor requirement. Thanks for your support and co-operation. Best Regards ### Assistant: Take a look at this article: https://rockwellautomation.custhelp.com/app/answers/detail/a_id/605924 If I understand it, the field voltage is not as important as matching the field current. Parameter 374 must match the dip switch setting for S14 (see page 60 of the PF DC User's manual for this critical dip switch configuration). Set the dip switch to match the motor field current from the motor nameplate, set parameter 374 to match, and supplying 220 to the field supply terminals should be fine. \n


### Human: Powerflex4, 40, 4M, 525 not following orders.... Summary: They do not follow cmd. freq. nor stop when told to. Hi all, Has anyone experienced their drives not following orders, such as command freq. (the drives tend to hunt around, even to go beyond max freq.) or what's worse, they don't stop when told to. When set to Decel to a stop, the drive tends to keep outputting a floating freq. (again, could be higher than max setting) and just stays running. One way to stop this is to set the drive to coast to a stop, but that's just a band aid. The drives are running as V/Hz. Now the problem seems to be related to the incoming 3ph power (imbalance from Edison), I can change up the three leads and the problem goes away sometimes, but I can't account for this when in the installed facility, this happens and the incoming seems fine and balanced. Any thoughts ?? Especially how to remedy this, I can't have drives not stopping on command. William ### Assistant: What is the slip frequency set to on each drive? \n


### Human: Kinetix 300 Save/Load Connection/Configuration wanted. Summary: Cannot find documentation explaining Save/Load functions. Please send linkI have to back existing configurations ons Kinetix 300 servo drives before making changes to a machine. I have never worked on these drives. There are Save Connection, Load Connection, Save Configuration and Load Configuration options on MotionView Onboard software. I cannot find a description telling me which one will do an upload for backup. It is not in the User's Manual. If you have a link a to a document explaining these, please send it to me. I would also like to know how to open the files offline. I cannot find that either. I think they are .dcf files. ### Assistant: Save / Load connection buttons take care of the communication setup. Save / Load configuration buttons take care of the servo settings excluding communication. Save button saves to your computer. Load button loads TO the drive. In order to view the settings off-line, you'll need to save the Java application which you use to access the drive (the one that you run in your web browser). If you save the Java app to your computer, you can then run that while off-line and open the configuration file. \n


### Human: PF755 over Ethernet/IP with CompactLogix Summary: How to setup the communication?Hi all, I have 2 PF755 suposelly communication with my CompactLogix. Everything looks ok but when I set the Reference value and the Start bit the drive does not start. I used the 755 Profile in Sudio 5000. Everything seems fine but I have the feeling that I am missing one little configuration like where the drive should read the reference and start/stop from. I did not change this as I think this is automatically done when the Tags are created by the profle. Is there a document that explains what exactly has to be setup? Thank you in advance for your help. Thales Jacques ### Assistant: Can you upload your ACD file for us to look at? Also, the DNO files for the drives? It may be nothing wrong with your ACD file, but rather the configuration of the drives themselves. \n


### Human: Powerflex DC 6.002 firmware anomalies Summary: The newest firmware might have a polarity problemMy company just commissioned two identical systems, one in October, one at the end of December. October's PF DC drive used 6.001 firmware. We downloaded the DNO file from it to the system commissioned in December, into a drive with 6.002 firmware. We had to swap motor and armature feedback leads to get proper directional control. 6.002 firmware fixed a certain anomaly involving adaptive speed gains. Rather than go through the whole speed tuning process again, we downgraded the firmware so that the adaptive gains which worked for the first installation would work in the second. We had to swap the motor and armature feedback leads back again in order to get directional control correct. One should not have to swap polarity just because you change the firmware. Has anyone else encountered this anomaly? ### Assistant: Interesting observation! You say motor and armature feedback leads, so was that the motor armature leads were swapped, and also the tacho leads were swapped? confirm please. I was responsible for finding an anomaly with V6.001 and alerting RA to it in that we had a special application where we wanted to employ external field control on a motor but at a fixed value (i.e. no weakening). We also wanted to employ the feedback bypass feature, where if the pulse encoder failed, the motor would revert to armature voltage control, but the firmware doesn't allow you to disable the internal field controller without having a feedback device (field configuration conflict alarm condition). The way around this was to select a permanent magnet field, but strangely enough when the motor was started the drive faulted on motor over-voltage. The reason for this is that the firmware had a bug where the motor speed feedback from reading the armature voltage was held at zero. This worked before V6.001 and was fixed in V6.002 Maybe there is a new bug introduced in this area in fixing the issue we had? \n


### Human: Powerflex 40 and 22-comm-e F081 on power up. Hello, I have been having a communication problem with several drives in control system after power is cycled whether it is off for 60 sec or 2 hours it doesn't matter I will get a F081 fault sometimes it will reset right off the bat by pushing stop button other times I could be there for 20 min waiting for the drive to indicate any power is going to the 22-comn-e and then when it does I may have too hit stop- button multiple times to get it to reset and communicate or the drive gets replaced and everything works as normal after replacing. I have replaced several drives out of this system that haven't been in service for very long with this problem so right now I'm am looking for a solution to fix problem if any. Thanks for the help in advance. ### Assistant: I have a couple of questions. How are your comm cables located in relation to your power cables? Are both your comm and power cables shielded, and shielded from each other? Are you actually losing comms or just getting the error? How long are you network cable runs? If there is nothing wrong with the physical installation, i.e. cable integrity, comm card, connections, etc, then I suspect noise in your comms lines. \n


### Human: Powerflex 525 vector mode explanation? Summary: What is velocity vector mode?We have recently learned that the PF525 drives in closed loop vector mode are not in flux vector control, they have what our local RA drives rep described as velocity vector control. He described it as glorified V/Hz mode with feedback. I see that the speed control specs are not as good as a flux vector drive. I've done some searching on the knowledgebase and in a general web search but I am finding nothing about velocity vector control. Can anyone explain a little more about it, perhaps a few points to compare/contrast with flux vector control? Thanks, Bob ### Assistant: nan \n


### Human: Powerflex 523 and connected components Summary: Connecting to 523 through connected componentsThis may be a simple question but i can seem to make it work. Is here a way to connect to a Powerflex 523 drive through Connected Components Workbench using the USB port on the control module? ### Assistant: No, the only way to connect live to the drive with CCW is to use the 1203-USB while the drive is powered. However, you can pre-configure you program in CCW, then export the file to a .pf5 format from CCW. Then plug your computer into the drive via the USB port in the back of the control module and import the .pf5 file to the drive. Once this is done, your drive should be programmed and ready for testing. See Chapter 2 of the User Manual; http://literature.rockwellautomation.com/idc/groups/literature/documents/um/520-um001_-en-e.pdf \n


### Human: Kinetix drive axis practical remove Summary: drive hardware removed, run the machine without too much changes in the projecta Kinetix 7000 drive and motor are actually removed from a machine. the project was engineered with RSLogix 5000 using motion axis control through Sercos interface 1756-M16SE. the fiber optic ring is closed again without the presence of the above drive. what is the simplest practical way to run the machine again without any faults? i was considering the Inhibit Axis feature, to avoid destroying the software. any recommendations from the experts? ### Assistant: Inhibit axis would work fine, but you're going to have to look at overall application logic and make patches around the logic which refers to this drive. If you don't do this, then the logic will stall while it waits for responses from that drive. It shouldn't take that long to go through the logic to pull out or patch around the references to the drive. Doing it now, while you're thinking about the drive, makes more sense than 2 years down the road. Some poor slob will be trying to debug the machine and see program references to some mystery drive that doesn't exist. \n


### Human: Drive executive and Kinetics 6500 over ethernet Summary: Drive executive and Kinetics 6500 over ethernet communucaitionDoes Drive executive work with Kinetics 6500 servo drives over ethernet with RSLinx? ### Assistant: I just opened it and tried to create a new file - K6500 is not an option. While you could access a PF755 drive which is controlled via CIP motion from a logix processor, any changes you could make to parameters are wiped out at the next power cycle. Drive Executive is not intended to work well with CIP motion hardware. \n


### Human: Kinetix 6500 module faults Summary: Spurious module faultsHere's hoping someone can help! I've been trying solve issues with spurious 'module faults' on a system with 7 axis. The faults have occurred across nearly all the servo drives, all with the same outcome; Once the servo axis has detected a module fault, an alarm is generated in the PLC and the system stopped. However, all the drives are seen to be healthy with no faults both on the drive display and via RS Logix 5000. Could this be a firmware issue? ### Assistant: What is the coarse update period for the motion group? These errors sound like it is too small. If you did not set the coarse update period, the default is 2 milliseconds. I would probably double it for your 7 axes, unless you have other motion axes as well (such as a PF755). I might even set it to 5 milliseconds to ensure no timing problems. \n


### Human: PowerFlex 400 Multiple Speed Sources Summary: Want two sources of speed Analog In and a PresetIs it possible to have multiple speed sources for the PowerFlex 400? What I'm trying to accomplish is to have a pump run normally throughout the day with the Analog In signal as the speed source. This is how it works now. Have a selector switch run the pump at max speed for clean up at night. For reference here is what I have: P035 - 80.0 Hz [Max Hz] P036 - 2 [2 Wire Start] P038 - Started out at 2 [Analog In 1], this is where I tried to set it up at 4 [Preset Freq] P039 - 30.0 Sec [Accel Time] P040 - 30.0 Sec [Deccel Time] T051 - 8 [Preset Frequency] T052 - 14 [Anlg1 InCtrl] T069 - 2 (4-20mA) [Analog In 1 Select] A144 - 80.0 Hz [Preset Frequecy 1] I have a switch going from the jumper of 01/11 to 02. This starts the drive. This works as desired. The Analog In for the speed reference is on terminals 13 (+) and 14 (Com). This is the speed reference. This works also as desired. What I tried to do was have a 2 way selector switch with Terminal 04 [Digital Common] on one end and it would either make contact with Terminal 05 [Digital In 1] or Terminal 06 [Digital In 2]. This did not work. The drive wouldn't even move. So I put P038 back to 2, and it worked like it did before. The DIP switch is on SRC... Should I move the wires from Terminal 04 to Terminal 01/11? Is what I'm thinking possible? Thanks. ### Assistant: I just tested this and answered my own question. Yes the common wire should be from Terminal 01/11 not Terminal 04. I guess this could be helpful for anyone else who may need it. \n


### Human: Powerflex 400 Summary: Motor high current/failureI have a Powerflex 400 Drive that is controlling a 30 HP motor and have had 2 motor failures in less than 1 month. There is no line reator installed and I don't know if it would help or not. The motor has a 1.15 service factor and I have used it numerous time without issues at other plants. The motor is loacted about 200 feet from the drive. It consistantly runs at a high current even with no load on the motor. FLA on the motor is 38 and though I initionally had about 20 amps of load; the load has increased overnight by 15. The conditions have not changed. Any idea as to why this motor may be failing? There are about 30 motors on this line and they have been running with no issues. I have now replaved the motor twice, the power cables once, and the VFD once. ### Assistant: I have a couple questions for you, what is the voltage of the drive and motor? What is the application you are performing with the drive and motor? A service factor rating in a motor is a rating similar to that of the OL rating on a drive, and the PF400 has an OL rating of 110% for one minute. Is there any output filtering between the drive and the motor? What type of cabling are you using? Is the motor VFD rated? Have a look at Chapter 5 of this guide; http://literature.rockwellautomation.com/idc/groups/literature/documents/in/drives-in001_-en-p.pdf It should help you to understand better what my questions are about. \n


### Human: Kinetix 350 Summary: Servo Motor Encoder questionHi everyone, here's the detail : Kinetix 350 (2097-V34PR6-LM) and a servo motor ### Assistant: The system does not move the motor if you perform a feedback-only test; you must move the motor shaft yourself. During the polarity test, you should have been given the chance to tell the system which way was positive rotation. \n


### Human: PowerFlex 70 not using the speed ref from the PLC Summary: The drive shows that the Ref Owner is DPI Port5 but the drive ramps up to 60hz anywayThe plant was recently hit by lightning and there was an AB 1336 Plus running a pump. The PLC was sending the speed reference to the 1336 via an different R I/O card. We upgraded to a Powerflex 70 with a 20-Comm-R card for Remote I/O communications. The new PF70 was installed with appropriate pump parameters. Also the following parameters were set: P90 (spd ref A Sel) set for 22 (DPI Port5), P274 and P276-285 (all set for bit 5 'DPI Port5'), P361-P366 (Dig inx) all set to '0'. The drive starts/stops when the PLC tells it to. There are no hardwired inputs. The problem is that even though the P292 (Reference Owner) shows as DPI Port 5, the drive ramps up to 60Hz (or whatever P82 is set to) even though I see P275 varying the way same as the PLC discrete output word. However P2 (command Freq) shows whatever is in P82 (Max Speed). Can anyone see a problem in this? I've been scratching my head a lot on this one and its starting to hurt. Any help would be appreciated. Thanks in advance for any support. ### Assistant: Hello, Looks to me like its not taking the Commanded Speed, Are you sending block transfer message to the drive? I wonder if something is missing on the adapter, Could you check the chapter #3 and make sure it's not disable. http://literature.rockwellautomation.com/idc/groups/literature/documents/um/20comm-um004_-en-p.pdf \n


### Human: why my autotuning on Powerlex 755 using rotate tune is unable to finish successfully? Summary: Always gives the tip that please verify if motor parameter is correct.Rotate tune unable to finish check parameters. I am having problems getting rotate tune to finish. I have reset the drive and used the drive wizard to set up to the motor name plate. I have a PF755 100 HP heavy duty or 125 normal duty drive. The motor is a Baldor Reliance RPM AC Motor. 100 HP at 1750 RPM, 119 Amps, 460 Volts, 60 HZ or 100 HP at 2000 RPM, 118 Amps 460 Volts at 68.5 Hz. I reset the drive to normal duty using Induction FV mode and set motor parameters to 100HP, 1750 RPM, 119 Amps, 460 Volt at 60 Hz. The motor has a 1024 Pulse tac for motor speed feeback and is uncoupled from load. Should I be resetting drive up for Heavy duty and what motor name plate data should I be using? Is there any other things I should be checking? Motor runs but it seems to over shoot when there is a speed set point change and will oscilate for a while and then settles out. I have played with the speed regulator tuning trying to settle it out with no luck. ### Assistant: Are you using Connected Components Workbench or Drive Executive to tune the drive, or are you commencing autotune from the HIM on the drive? If using the HIM, before you enter the autotune menu, change parameter 71 (Autotune Torque) to 100. The default is 50%, and that is sometimes not enough for autotune. If using CCW or Drive Executive, the Autotune Torque setting is on the Autotune page and the Inertia tune page - set it to 100 before beginning the autotune. \n


### Human: powerFlex4 f005 error I am using a powerflex4 inverter with 0.75 kw rating 1-phase input and there is an error f005 (over voltage error) is appearing at power up and it is disappear after many tries of clearing the fault and restart it . and when I shut the power off for a time and want to run it again this fault appear again .note that : I am using it's appropriate EMC filter and input line voltage not exceeds it's recommended value (265 v) and when I measured the voltage at dc terminal it is around 308 v (normal value ) so I am kindly asking about guide to know what is the problem and what is solution ..... thanks ### Assistant: If this is happening at power-on, your line-in voltage is too high. It may be below the 265V max, but it needs to be closer to the nominal 240V recommended. Also, if you're cycling power, you need to give the drive bus capacitors time to discharge before applying power again. If you're cycling off-on more frequently than one minute, the bus voltage doesn't decay low enough and you end up with an F5 fault on power-up. \n

### Human: PF755 - CIP motion and I/O cinfiguration Summary: Problem with adding PF755 drive in ControlLogix controller organizerHi everyone, I can't get rid of fault state of PF755 in I/O configuration. I try to add drive as CIP motion (PowerFlex 755-EENET-CM), I create an axis and connect it to the drive, but there is a fault of drive definition.

Also show us an image of the Module Definition when you click the CHANGE button on the General tab. \n


### Human: rotery motor hello i work with kinetix 6000 and a motor how drive a plateau with 8 steps. each step = 45deg. When the motor turns 1 time around the plateau turns 3deg. My start position (he gives) 215 not zero. i thought count (+45deg offset) every time. but when he goes up 360deg he gives error. or is it something like this: (215 - 215) + X This X first time 0deg afther this every time +45deg. but how i go from 360deg to the home step? can someone help me ? ### Assistant: Hans, sorry, I'm having difficulties understanding your problem. It sounds like you have a rotary table driven by a motor. You want the table to index 8 steps in a machine cycle, each step is 45 degrees. The table moves 3 degrees for each motor revolution. Have I stated it correctly? If that is true, you have a 15:1 reduction ratio between the motor and the table, correct? To take full advantage of integrated motion within Logix5000, you should be putting some of those parameters into the axis definition so that your motion commands work in terms of real, useful units. Putting the 15:1 reduction ratio into the axis definition will let you issue motion commands in degrees of rotation of the table. Can you tell us what error you are getting? Just telling us that you're getting an error isn't enough; there are a lot of possible motion errors. Can you upload your logix 5000 ACD file for us to look at? \n


### Human: 1398-PDM Error 33 Summary: IAVG Error with motor detachedI have a customer out in the field that has the following setup 1398-PDM-150B Drive H-8500 Motor They receive an Error 33 IAVG fault with the motor detached from the machine. It appears they can cycle the motor for a short time period before it starts to fault (20 cycles or so). Duty cycle is about 1 stroke every 4 seconds. If they try to increase the speed it will fault out quicker. I have had them pull and check the encoder and power connections and make sure they are clean. The drive has 230 VAC feeding the drive and control. They have 350VDC in the DC bus. What else could I look at?? Thanks ### Assistant: Were they able to try a spare motor? If the trouble goes away with a different motor, I would suggest that the motor bearings were starting to fail. Did the motor have a brake on it? Even if they were not using the brake, the wear on the disc spinning in the housing can cause enough drag that might cause the motor to fault. \n


### Human: communication Summary: 1203-SSS and powerflex700Hello, I'm trying communicate between software drive executive and the inverter powerflex700, but I'm facing some problems to get communication. I'm using 1203-SSS converter. I' want to know if is possible use this converte to communicate. Regards AAguiar ### Assistant: Check which series of Anacanda it is on the label, is it a series A or B? The series A apparently so I have read will not work with DPI interface (only scanport) but a series B will. You may need to ensure the driver for it is installed on your PC. Also check it is present in the Control Panel... Device Manager.... Ports (Com & LPT) section, where you can also check the Com port # and the settings of it to talk to the device. Also remember an Anacanda is powered by the drive DPI port, not the PC so it can't be checked unless it is inserted into a powered up drive unit. Regards Damian \n


### Human: PF 753 on conveyor belt Summary: any advice to improve the performance of the Drive ? ### Assistant: You're going to have to give us a lot more information if we're going to be able to help.

### Human: 755 - No fault, no alarm - RUNs but produces no output Summary: Drive is ENABLED, but T1/T2/T3 always=0, HIM says there's an output Power the drive. (No on-site firmware updates have been done…running just as it came from the factory – 11.001) Reset the drive, and each peripheral device, to Factory Settings, using the HIM. Measure the DC+/DC- terminals, = ~680VAC Run the HIM-driven commissioning steps (with exception of autotune), and tell the drive that the HIM should be able to start/stop the drive. Attempt to run the drive. Drive front panel shows an output (in this case, 15HZ), and also it shows an output voltage (~120V). HOWEVER THERE IS NO OUTPUT ON THE T1,T2,T3 TERMINALS. Repeated the effort by loading a parameter set from a good drive, and running the drive from Drive Executive (directly connected to drive with ethernet cable between drive and laptop…just as with the prior good drive). All indications are that the drive is running and producing an output, but nothing shows on the output terminals, wired to a motor or open loop. Removed SafeOff connector, and indication changes from Enabled to Not Enabled. So, the summary of the problem is that both the HIM and DriveExecutive show that the drive is creating an output, both in HZ and volts, but nothing is measured on the drive terminals, connected or unconnected. My biggest concern is why the Drive Output Volts parameter, which claims to be representative of the voltage on T1/T2/T3 would differ, at ALL. Cat. No: 20G11ND5P0AA0NNNNN Series A Firmware: 11.001 Serial Number: 40575849 Options: DriveLogix Ethernet/IP SafeOff Encoder 24I/O HIM ### Assistant: There's nothing wrong with your procedures for startup. We've encountered this problem a couple of times; replacing the drive is the only solution we've discovered. Rockwell has provided no explanation at this point. \n


### Human: PF40M on a crane Summary: Misapplication of the PF40M?A customer is trying to use a PF40M on a crane hoist. They are getting Over Current faults. There doesn't appear to be a good drive parameter configuration for the use of a PF40M in this application. I think they need to bite the bullet and use a PF700 or a PF755 type drive. If I'm wrong, has anyone successfully applied the PF40M on a hoist? If so what's the secret parameter configuration? ### Assistant: A PF755 would be much much better, but the drive also needs to be sized correctly. It sounds like the drive is not large enough for the load. \n


### Human: Servo Motors and Air Cylinders Hi, I'm looking for a way to make an air cylinder reach its extended position when my servo axis reaches a certain position. The cylinder and servo are 2 separate things. The servo is controlling an elevator type device (up/down) and the cylinder moves a knob in/out to the elevator. Since my cylinder takes n-seconds to reach its extended position (from retract) no mater what speed my servo goes, how can I make sure the cylinder reaches its extended position at the same time that my servo passes/stops at a certain position? I'm using an MAM for the servo. I'm thinking that after I start the MAM, there is a known motion profile for the servo drive controller to follow. Can I determine what position the servo will be at n-seconds before the end of the planned move? Or use some sort of output cam? Thanks, Denis. ### Assistant: It sounds like you do not have feedback from the air cylinder - you do not know its position as it moves. Without feedback, this is not going to be very precise. Your air cylinder speed is completely dependent on air pressure. Any changes or fluctuations are going to change your speed/position calculations. That said, if all you have is the time that it takes for the cylinder to extend, instead of using a Motion Axis Move (MAM) command, use a Motion Axis Time Cam (MATC) instruction. Look at the Logix help file for MATC to see how to use it. Also refer to the motion instruction reference manual: http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/motion-rm002_-en-p.pdf \n


### Human: PowerFlex DC Drive current limit Summary: How to achieve drive full O/L capacityIt seems that the PowerFlex DC drive will only allow an output current capacity relative to the motor name plate FLC, regardless of being in ND or HD mode, and will not output anymore current even though the drive is overrated for the motor. My situation is the motor FLC Parameter[179]=180A therefore the drive will only output 150% & 200% in ND mode = 270A/360A and 200% & 250% in HD mode = 360A/450A, even though the capacity of the drive is 250A (150% & 200% should be 375A/500A in ND mode). We are installing on a Steel Mill roller table which requires +425A at times on heavy sections. Any thoughts or advice please. ### Assistant: The drive may be oversized relative to the motor, but that's the point of parameter 179. Giving the motor nameplate current will permit the drive to set the overloads relative to the motor. 200% overload for your 180A motor is rather less than 425 that you want. Is the PFDC replacing something, or is this a new installation? Your statements would make it seem the DC motor is undersized for the loads. \n


### Human: Powerflex 755 Fault on Ethernet error Hello I'm looking for a way to disable ALL drive faults associated with using an embedded Ethernet module with Powerflex 753/755 drives. We will be using hard-wired control, but Ethernet for monitoring purposes. We don't want any Ethernet errors/issues to fault the drive when it's online. I'm currently testing with a PF755 demo setup, and have been unsuccessful in figuring out how to disable those faults. Any help is appreciated. Thank you ### Assistant: Set Comm Flt Action to something other than fault. Selecting hold last, or zero data should work. PF755, port 13, parameters 54-57 PF753, port of ENETR card, parameters 33-36 \n


### Human: PowerFlex 700S Phase I versus Phase II control Summary: which should I choose for a new project? (if there is a choice)Hi, After doing a lot of reading and asking many questions here on this forum, I believe the PowerFlex 700S is the drive best suited for my particular web handling application in which I need two drives that will work on 208/240 VAC and that will allow me to configure them in a master/follower arrangement in which the follower drive will monitor feedback from two encoders (one on the follower motor and one on the master motor), and will allow me to control follower motor speed at a ratio of the master motor speed. As I have started to read the PF700S literature in an attempt to pick out the actual catalog numbers that I will want to buy, I see that the PF700S has (at least at one time), come with two varieties of control hardware - Phase I and Phase II. From what I can tell, Phase II seems to be newer and better, and I don't see any reason why I would want to consider Phase I for a brand new project. If anyone can tell me if my understanding of this is correct, or if I am missing something, I would greatly appreciate it. Thanks in advance, Paul ### Assistant: Paul, go here: http://raise.rockwellautomation.com/RAConfig/browsecatalog.asp?LID=ABStdProds,Encompass&onKil=http://www.ab.com/raise It's the on-line configurator for most of Rockwell's product line. Go to Drives AB, Architecture Drives, and select PF700S Work from top to bottom. You'll see that there is only phase-II available. Running through the configurator will quickly help you determine exactly what you need; the options self-limit so you do not create an impossible part number. \n


### Human: Error code on the MCCP instruction Summary: Error code 31 produced on the MCCP instruction Dear all Sometimes as the instruction MCCP is engaged,error code 31 is produced on the MCCP motion structure control word. I check in the user manual says cam profile is still in use. But in my program Pcam instruction is all disabled. Anyone met that situation? ### Assistant: I am having a similar problem with error code 31... Did you ever find resolution to this issue? thanks, Josh Williams \n


### Human: PowerFlex 755 , High Starting Current Summary: PowerFlex 755 , High Starting CurrentDear all , The problem description :I have a blower on a powerFlex 755 I have a problem with starting the blower , I did many trials . What happened at the beginning that the frequency of the blower was over shooting , for example the setpoint was 15 Hz and it reached 22 Hz and then it came down to 15 , but the current was high . After trying many trials , what is happening now is that the current is high at starting . It looks like that the blower is running faster than the calculation of the frequency drive . I tried to make the starting time longer or shorter , didn’t help . At the beginning the current go up and down several times and then it reaches a peek and then starts to go down to normal current Does anyone have any idea ? ### Assistant: How is the drive configured? Flux Vector, V/Hz? It sounds like it a PID routine is trying to control the drive. Try putting the drive in V/Hz mode and see what happens when you tell it to start and ramp to a set speed. If it starts in a satisfactory manner in that simple setup, then your PID is trying too hard to control the drive. \n


### Human: powerflex 753 DPI error I have a powerflex 753 that is getting a DPI error from port 2 the HIM module, this fault causes the drive to shutdown. is there any way to have the drive hold last state and not fault? thank You ### Assistant: A DPI error from the HIM cannot be ignored, the HIM may be asserting a stop. Make sure you are not using a datalink to modify a parameter that cannot be changed (refer to knowledgebase article 62479). Check the connection between the HIM cradle and the main control board. Try swapping HIM's. Contact free drive tech support at (262) 512-8176. \n
