### Human: Ultra3000 Velocity Limit I am using a Ultra3000 (2098-DSD-010) in analog position mode. I'm trying to find a way to limit the maximum velocity of the motor. I'm not to concern with following errors or position errors. I just need it to move to a commanded position without going over a maximum velocity. Does anybody know if this is possible? ### Assistant: There is no max velocity setting when the drive is in analog position mode. The speed of the motor will depend on how quickly the analog position reference changes (dV/dt). You can set a user velocity fault speed (in the faults section of Ultraware) but this will simply generate a drive fault when the drive speed exceeds the limit you set. Depending on you application you might be better off using an indexing drive or an integrated motion drive. \n


### Human: more curent on PowerFlex 70EC hi all! I've a PowerFlex 70EC for 37 kw motor, with NP 65A, the motor is working in the limit, I wish to try to put 2 amps more, the parameters to change are 42, 47 and 48? thanks ### Assistant: nan \n


### Human: Does the Motion Database file with MPM-A1653-S is an alternative for MPM-A1653F-S? Dear all, I can not choose the correct Catalog Number MPM-A1653F-S from the Motion Database file [motion_5_14_0.db], for the motor catalog MPM-A1653F-SJ72AA. After I choose the MPM-A1653-S and Turning, Using Motion Director Commands , The Motor running with very big noise, and the position error is more than 10 degree ( 360 Degree per motor resolution ). The same Turning setting for other 17 pieces of MPM-A1652F-S and MPM-A1651F-S. These motors do not have any abnormal noise, and the position error is less than 0.01 degree. Please help me to check how to get the optimal motor data setting. Thanks! ### Assistant: I'm unable to define it is the same motor or not, just to report I've checked the same weirdness in the latest version 18 of RSLogix 5000, that should have the version 6.9.0 of the motor database... :smileysurprised: I suggest to call in Technical Support, they should be able to help you better.... - fuzzy logic \n


### Human: PowerFlex 525 periodically dropping run command I'm using a PowerFlex 525-EENET with embedded ethernet and revision 1.3. This is being used on a pump that is being constantly turned off and on by a level control. I have added traps in the program to capture every possible reason the pump could be losing run command but it captures nothing. In the program, when the problem is happening, the run command is active, but the output on the VFD is 0. Simply re-sending the run command corrects the problem. I was wondering if anyone else was having this same issue with 525s. ### Assistant: The PowerFlex 525 doesn't have a run command in the logic control word, it only has start and stop (PF525_Drive_Name:O.Start and PF525_Drive_Name:O.Stop). If the PLC sends a 'run' command then it must be doing additional logic to determine how the start and stop bits are controlled when the 'run' bit turns on and off. I would suggest setting up some logic to capture if the stop bit is ever put high when it shouldn't. For instance put an OTL instruction with a dummy tag in series with the drive stop command bit, if the dummy tag ever gets latched high then you know that a stop command was issued at some point and the problem probably lies somewhere in your program. Also, confirm that a stop is not being issued from any of the following sources: Network Stop tag Remote HIM Stop button Dedicated Stop input terminal 01/11 Configured Stop input via DigIn TermBlk SW Enable via DigIn TermBlk Safe Torque Off \n


### Human: PowerFlex 755 frequency control Hello guys. Since now I have been used two PowerFlex 755 as motion control with 2 axis. Right now, our aplication requires that the 2 PF755 will work as a normal variator frequency control or speed control. How can I configure the drive from LogixDesigner to work as a PowerFlex 525? Right now I have added a new axis and configure the axis as Frequency Cotrol with no feedback configuration. The data type has to be AXIS_CIP_DRIVE? ### Assistant: You'd just like it to operate like a non-motion, regular VFD? You wouldn't add it as an Axis in that case; you can just add the drive under the I/O configuration and it'll automatically create the Feedback and Reference tags for you! \n


### Human: feedback data loss factory limit kinetix 350 Summary: Fault 45Hi everyone, here's the detail : Kinetix 350 (2097-V33PR3-LM) and a servo motor ### Assistant: http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/motion-rm003_-en-p.pdf Chapter 2, page 253 describes this problem somewhat. It's basically telling you you've got a connection problem or you have noise coming in on the feedback cable. Page 249 says to use a MSG command to get the RA specific exception (to get the fault subcode), page 257 shows how the bits are mapped. Suggestions: Remove the feedback connectors from motor and drive. Inspect each end, inspect the drive pins, motor pins. Look for something wrong with the connector. If there are screw terminations involved, make sure all conductors are properly seated. Make sure you follow Rockwell's grounding practices with regard to drive and motor. If none of that solves the problem, then: Change the cable. Change the motor. \n

Could someone give me some advice? Thanks ### Assistant: nan \n


### Human: Motion Control On Standard toshiba AC drives Summary: is it possible to control a standard ac drive using motion commandsMy goal is to use a compactlogix platform to create a master/slave setup using 2 toshiba G9 drives. Does anyone know if this is possible. i would like to use the motion instructions to control the drives speed outputs. i will be using a multi-turn absolute encoder on each motor the drives control. my thoughts are to use virtual axis in the program and map the output to the drives speed commands. ### Assistant: Compact Analog I/O is pretty slow, this would be my concern with trying to do this. All depends how tight you need the control to be. I've done things like this without using motion instructions, and it all comes down to how much precision you need and how much lag(and error) you can tolerate. What happens if they get out of sync? Is this a vertical application with brakes or horizontal? Or is it material handling? Really hard to give a general answer. \n


### Human: Kinetix 5500 using POINTIO digital input as home sensor Summary: using digit input as home sensorIs it possible to use a digital input acquired by a POINTIO as homing sensor for Kinetix 5500? (avoiding wiring the home sensor straight into the drive) ### Assistant: There's a couple of options. Jog the axis and execute an MRP (on actual position) when the sensor goes high, followed by an absolute MAM to your home position. The home offset would be accounted for in the position you give the MRP instruction. Set the axis homing for passive-immediate and follow the first option, except use an MAH in place of the MRP. This method will set AxisHomedStatus if you need to use that elsewhere. In either case, the accuracy will be affected by the delay of the sensor input, your code and the coarse update rate, multiplied by the speed at which you're jogging. Jogging as slow as possible would obviously improve that. With a little more code, you can have a faster approach speed followed by slower homing speed which mimics a normal bidirectional active-switch/marker homing method. \n


### Human: PowerFlex 755 HiP Summary: Codigos de error 49 y 48 en display de 7 segmentos en el interior del power flex 755 HiPTengo un problema con un PowerFlex 755 HiP, los fusibles de entrada antes de la bobina de choque (reactor), se abrieron, despues se volvio a reponer los fusibles, pero al energizar el drive me sale un codigo de error en el display de 7 segmentos de 49. Posteriormente se cambio por otro PowerFlex 755, y ahora sale codigo de error 48 en display de 7 segmentos. que se esta suscitando en estos casos y como podria solucinarlo? gracias por su respuesta.. ### Assistant: 48 is not a fault in the normal sense. It is an entry in the fault log telling you that it was commanded to set its parameters back to default values. 49 is also not a fault in the normal sense. It is an entry in the fault log telling you that the drive went through a power cycle. I hope that Google Translate did a good enough job for you to understand this. 48 no es un fallo en el sentido normal. Es una entrada en el registro de fallos que le dice que se ordenó para establecer sus parámetros con valores por defecto. También 49 no es un fallo en el sentido normal. Es una entrada en el registro de fallos que le dice que la unidad pasó por un ciclo de potencia. Espero que Google Traducir hizo un buen trabajo para que usted entienda esto. \n


### Human: kinetix 2000 changing (overtravel) pick n place position Summary: The horizontal axis on our automation is changing the set point the robot picks the part up at causing damage on part.How it works is the arm uses two axis horizontal and vertical the robot will pick up parts and place them in a tray. for example At start up the pick position set point would be set at 8.03 and while running the set point changes and it starts picking parts up at the position 8.53. that's .50 off from where it should be. when this change occurs the machine runs until we discover damaged parts. Any info on this matter would help. ### Assistant: Korben, the Kinetix 2000 gets all of its control commands from a Logix processor; it does nothing by itself. To help you, we're going to need a LOT more information. To start, you should share the ACD file from the logix processor so that people here can look at the logic. If you choose to share it with us, you'll need to identify which axis within the program is giving you problems. Is there ANY chance that something mechanical is slipping? You seem to be mixing terms in your problem statement. You talk about the set point position being 8.3, but the pickup position is 8.53. This last number - did you measure it yourself, or did the system HMI display the feedback position as 8.53, or did the position set point actually show as being changed to 8.53? The basic question to ask is: WHAT CHANGED? If the system was running well at some point in the past (yesterday, last week, whatever), but now behaves differently, WHAT CHANGED? Did a drive get replaced? Did a motor get replaced? Did the load the servo moves increase or decrease? If it used to work, and now does not, something changed. \n


### Human: Powerflex 755 with Universal feedback Module with 12V Encoder Summary: Cofigure an encoder with PowerFlex 755 using Universal Feedback Module Dear all, As i am bit new with the encoder. Implementing an application in which, i am using a brake motor with encoder which will give position feedback to Powerflex 755VFD. Can anyone please help me regarding the configuration of this encoder with universal feedback module.? Powerflex 755 is on ethernet with my compact logix controller. I want position feedback in my drive tags shown in controller tags of RSLogix 5000. Encoder terminal is shown in attached picture. Any help in terms of manual or guidance will be highly appreciated. ### Assistant: Would you please give us the manufacturer and part number of your encoder? \n


### Human: Kinetix 300 Step and direction mode Summary: How do you set-up and verify operation?I am trying to set-up an K300 in step and direction mode. Replacing a third party unit that was set-up as a step and direction using an AMCI module. I am looking for information on what exactly is required to make this unit actually run in a step and direction mode. ### Assistant: http://literature.rockwellautomation.com/idc/groups/literature/documents/um/2097-um001_-en-p.pdf Assuming you have the drive completely wired already, you should probably start with chapter 6 on page 126. After that you will probably need to reference Chapter 5 for details on the MotionView software. There are entries in the various chapters for step and direction hookups and configuration. \n


### Human: Single VFD PF755 multiple motors, get overcurrent F12 fault Summary: Single VFD PF755 multiple motors, get overcurrent F12 faultMultiple Motor Application Considerations 502708 The article above did not mention how to deal with autotune. Some articles on some forum says do not autotune for the single VFD multiple motor. Then how to deal with autotune options? skip it or set to ready or calculate? We face F12 HwOvercurrent fault when running one drive 2 motors application. We disabled slip compensation like KB says, but the fault still comes up. Any suggestions? Thank you ### Assistant: my colleague did autotune the drive, with two motors connected, I saw some articles that this will confuse VFD for the motor model is based on one motor only. But how to deal with the autotune options, thank you \n


### Human: Loading motion programs into an IMC-110 module using ODS and a PIC I have a customer with an older SLC-503 machine that lost memory from the IMC-110 motion module. We have the .amp programs, the old ODS floppy's and a PIC, but it's been fifteen years since I've used ODS. I have some old AB documentation, but it only refers to Windows NT. Will ODS install and run on a modern laptop, in a DOS window within XP? Do you still need to change the Config.sys and Path files, FILES=20 etc? Is RSLinx involved? Does it require a PIC driver to be added? If you understand any of this, you've been at this a long time. Thanks for any help! ### Assistant: First, I've to say I'm not an expert on that ...:smileysurprised: but, just trying to give some help... I've just found a statement about Windows operating systems, as follow: 8100-HS110 ...this software runs on DOS systems only. Windows DOS on 95 and 98 is acceptable. Any infos about XP...:smileysad: Also, for what I can say, RSLinx shouldn't be involved, as you need to use the software in DOS mode... I guess the 8100 software has its driver for the PIC to use... - fuzzy logic \n


### Human: Servo Action Status Summary: Trying to issue a MSO or MSF while axis is in motion.I have been getting this error on a few occasions lately and this had not been a problem in the past and there has been no logic change to the servo group. My first question is where does the ServoStatusAction bit reside, I am thinking it is in the drive amp. The motion group is started and runs for whatever and then we get a fault which states what I have put in the topic summary. This is error code 22 and stems from the Motion Control Tag. For some reason the servo action status bit changes state, goes to a 0, while we are running and in a group of 7 servos this is the only one that appears to be doing this. I have changed the amp and it went away for a week or so but now it is doing it again. When this happens there is no physical fault on the drive just a fault on the motion group. Any ideas on what may be happening here would certainly be appreciated. ### Assistant: Your code is trying to turn the drive on while it is already on and moving. This is not a drive problem. Some part of your logic is trying to re-issue the MSO command after the drive is already on. http://literature.rockwellautomation.com/idc/groups/literature/documents/um/motion-um003_-en-p.pdf Look at the top rung of page 337 in the link above. using my_servo_axis.servoactionstatus in this manner will prevent the error you are getting. \n


### Human: Ultra3000 Using ultra3000 drives with a Sercos Interface on Clx, is there a way to get the fault code displayed on the front of the drive into a PLC register? Thanks ### Assistant: Yeah I would like to know about this also! If anyone has any clues!:manwink: \n


### Human: Let shunt resistor work----K350 I have a 2097-Rx shunt resistor install on a Kinetix 350 But I don't configure the software let shunt resistor work My English is poor, I hope you can understand, thank you ### Assistant: Open the drive properties (from the IO tree), go to the Power tab, make sure the Bus Regulator Action is set to Shunt Regulator. This is should be the only software configuration that is needed to set up the resistor. \n

### Human: PF 755 syncronized velocity Hello experts. I want to impelement a application with 2 PF755 involved. They are configurated as thw differenet axes in the same Motion Group as Position Loop. The first drive moves at a certain velocity using the JOG command, and I want that the second drive to move at the same velocity as the first one. They have differnent gear reduction, so I was thinking of using the MAG instruction. It wil be ok? ### Assistant: That is exactly what the MAG instruction is for. You'll need to configure your axes properly - the configuration is where you would enter the gear ratios (though they are not called that precisely). Spend time reviewing the programming manuals for CIP motion to understand the axis configuration. \n


### Human: Motor Starter and Timer Summary: Looking for help wiring a motor starterHey guys, I am looking for some help wiring a motor starter with a timing relay in the control circuit. I attached a sketch of what I think will achieve my purpose: using a start button to turn on a motor for 10 seconds, and then turning off automatically, with a stop button as a failsafe. My questions are more on the wiring end. If I am pulling 34 F.L. amps through the contactor, I should use heavier gauge wire. I am assuming I can use smaller wire for the controls circuit, but how much smaller? What type of current will the control circuit see? What are the standards for wire colors (as well as colors of hot wires at full voltage vs. hot wires that aren't)? I appreciate any help. Thanks, Zach ### Assistant: You're using line voltage for your control circuit? Which diagram should we be looking at? The top one showing a 3-phase motor, or the bottom one showing a 1-phase motor? What IS your line voltage? \n


### Human: Aux encoder with K5500 I need to add a linear encoder to a Kinetix 5500 axis, controlled by a 1769-L33ERM. The 5500 has no auxiliary feedback input so my plan is to use the 1769-HSC to input the encoder signal. I would like some suggestions on how to program the linear scale. One thought I had was to take the difference between the motor encoder and linear encoder positions and add that difference to a MAM instruction's command position. This seems like the least clever solution. Someone had suggested that I create a virtual axis and use the linear encoder as its feedback device, but I do not see a way to do this. If I could do this then this seems like a more elegant solution--I could use a MAG or MDAC to follow the virtual axis in that case. Any other ideas? Thanks! ### Assistant: I don't think you have many choices. K5500 drives are intended to be low-cost, so do not have all of the features that a K6500 has. One possibility might be to purchase the lowest-cost K350 drive and hook your encoder to that. You don't need a motor; the drive would act simply as a place to bring the linear encoder in as a CIP axis. Then your MAG or MDAC approach would work. Is too late to change to a K6500 drive? What is the data format of the linear encoder? \n

### Human: Kinetix drivers Summary: Load the parameters setting automatically from PLC programHello, 1-Is it possible to load the parameters setting automatically for Kinetix 300 using RS Logix 5000 ? If this possible,explain how to do it? 2-For the Kintix drivers which the parameters loaded automatically from PLC program,when replace the driver with another,it should use another one with the same type or it possible to use any equivalent one? Best regards......... ### Assistant: Mr. PLC, the K300 isn't really intended to function that way. The K350 WILL do what you want, automatically. The K2000, K6000, K6300, K6500 will as well. The K300 drive is intended to be a stand-alone indexing drive. It IS possible to send move commands (position, speed, accel, etc.). There are add-on instructions available in the Motion Accelerator Toolkit to run a K300 from Logix5000. I've never tried to change any configuration parameters of a K300 drive from Logix, however. If you have not already purchased the K300 drive, I strongly suggest you switch over to the K350. The K350 is intended to be controlled from a Logix environment. All of the drive parameters are set and adjusted from Logix, are stored with the Logix application. To answer your second question, if you replace a Kinetix drive with an equivalent one, you should not have to do anything at all. If you put in a drive from the same family but larger power, you may have to adjust some parameters in the I/O tree and the axis properties. If you replace one Kinetix drive with another of a completely different family (say, replace a K350 with a K6000), you will likely have a number of parameters to adjust, but it wouldn't take long. \n


### Human: Kinetix 5500 and safety PLC I have a Kinetix5500 to control a press system. Limit switches (overtravel) are connected via safety input card on a POINT IO (they are not hardwired to the drive). How can I perform a safe stop of the motor in the safety PLC when these overtravel sensors are reached? thank you ### Assistant: The K5500 does not take safety commands over Ethernet/IP; it has a safe-torque-off input which disables the drive. I think you would have to receive the limit switches in the safety task, pass the limit switch state over to the regular PLC task. While the regular PLC task performs a controlled stop, the safety task would time-delay before opening the safe-torque-off circuit of the drive to disable it. I think the amount of information you can pass between safety and regular tasks is somewhat constrained. \n


### Human: PF753 Overcurrent Issue Summary: 40HP PF753 will only ramp to approx 20Hz then decel's back to 5Hz and tries again480VAC 40HP PF753 on ENETR will only ramp to approx 20Hz as the current draw approaches 90A then decelerates back down to 2 or 3 Hz and attempts to accelerate again, but current draws near 90A again. This continues over and over until I shut the drive off in fear of damaging the motor or the equipment. I can turn the motor shaft with a large monkey wrench (and some help), so I do not think it is bound up. Has anyone seem this before? ### Assistant: Yes. Are you sure the velocity command is correctly configured in the datalinks of your plc program as well as in the drive itself? Is the drive properly configured to take its speed reference from the network? \n


### Human: CCW PF700. Which one? I am runnig CCW ver8.00. I tried to connect to one of our pf 700 drives. However, in the ccw drives catalog there are 7 different pf700s. None of them seem to match up with the cat no. on my pf 700 drive. Which one do I choose? ### Assistant: Let's start with how you're connecting to your PF700. Ethernet? 1203-USB? or something else? All you should have to do is pick the drive from the connection tree when you press the DISCOVER button. \n


### Human: gearing Summary: Servo MAG to local encoderhave a machine with several Kinetix 350's connected to a CompactLogix L33-ERM processor. Have no problem gearing them together, or to an Ether/IP encoder. Can't seem to find method to gear to an encoder connected to a local HSC module. Any suggestions? Thanks, Bob ### Assistant: In short - YOU CAN'T. The master encoder has to come into the logix system either as a CIP-Motion encoder, or in one of several drives which take auxiliary encoders (the K2K, K6K drives do). CIP-Motion encoders are expensive enough that it's cheaper to purchase the least-expensive K350 drive and bring the encoder into the system there. Don't bother with a servo motor, just connect your encoder to this drive. \n

### Human: Vector Control for Powerflex 70EC Summary: What is FVC Vector mode?Can I run a powerflex 70 EC in FVC vector mode without an encoder? ### Assistant: No you can not. The Flux Vector Control algorithm uses the encoder speed feedback and compares it to the speed reference.

### Human: Powerflex 753 lower voltage question Summary: Will my VFD run on 220V single phase?Hello All, I have a unique short term situation. I have a Powerflex 753 drive Cat ### Assistant: Sorry, that you cannot do. The 750 series is 400V and above. Single phase will work, but the voltage has to be there, and you can't change that. Single phasing means you will have to derate the drive as well. \n


### Human: PF 700 F5 Fault - Summary: Is this a bad cap problem or do I replace the drive2009 PF700 throwing an F5 Fault the instant the motor is called to run. Troubleshooting guide says that if this happens when the drive is accelerating its most likely incoming voltage. . . Incoming voltage is fine, Input Waveform gets distorted when drive attempts to start the motor (as the pic below shows). Motor tests fine. Buss voltage is around 750VDC when not being called to run Is there a capacitor issue at play here or does the drive just need to be replaced ### Assistant: Sounds like your AC line is high. The DC bus on a 480V drive should be around 680V when stopped (480 * sqrt(2) = 678.8). From the screen shot of your power quality meter the AB voltage is almost 500V. Verify the taps on the incoming transformer are set correctly. \n


### Human: Module DEVICENET - SOFTLOGIX 5860 Summary: i don't have module devicenet in chassis Softlogix 5860 21.0 Anyone could tell me how to get the module DEVICENET oR CONTROLNET in the chassis of Softlogix, I can't simulate my network devicenet...please if you give me a solution i can give you a pressent of licence from rockwell ### Assistant: I'm pretty sure Softlogix only uses Ethernet for communications to the real world. I think you'd need a ControlLogix rack with a 1756-ENxT module and an 1756-DNB to act as the bridge between the two networks. Is there any chance of simply eliminating the Devicenet and going with Ethernet/IP? You will be much, much, much happier if you go that route. \n


### Human: PowerFlex 525 Encoder module Positioning of the Encoder Summary: Encoder location PowerFlex 525 PostioningI have been testing the 25-ENC-1 Encoder module with the PowerFlex 525 Drives on the test bench. Setting up the Drive as an indexing drive to binary select the setpoint when Position Mode (P558) is set to Preset Input. The trouble I'm having is placement of the encoder. When I couple the Encoder to the Motor Fan shaft I get desirable speed and positioning of the Output shaft on a 60:1 gear box. But if I couple the encoder to the output of the gear box and change the Counts Per Unit (P559) my motor speed is extremely slow but positioning is correct. The system eventually get to the preset position only it takes a few minutes to get there. I have tried to adjust the gains as the user manual suggested even as far as to the extremes. Lowered the Pos Reg Filter (P565) to 1 and raised the Pos Reg Gain (P566) to Max 200 but still no response to very little. I understand that this is not to replace a high end servo system but there are a few places on our plant floor that the cost of Servo system outweighs the benefit. I would like to find a solution to mounting the encoder to the tool vs the motor. In many application this is more practical and easily done. ### Assistant: You should set the parameter A536=Encoder PPR/60 when you couple the encoder to output shaft of the reduction gear box . \n

### Human: PowerFlex 252 Drive Summary: Drive Trips just powered upI have a PowerFlex 525 VFD that is tripping just setting in the enclosure powered up waiting to run with no other conditions, we have n inline reactor and the phase voltage is 585 phase to phase, anyone have a suggestion ? ### Assistant: What is the fault? If it is a 480V drive then 585V phase to phase is REALLY high. That would mean your DC bus is 827V and the drive will fault at 800V. Check the taps on the incoming transformer. \n


### Human: PowerFlex 700 VC Ground Fault Issue Summary: VFD goes to ground fault and issue is only resolved by replacing the driveWe have an application where a 132 kW motor is installed and PowerFlex 700 VC 400V 260A Series B is being used to control it. We are facing a recurring issue on this application where the drive goes to Ground Fault and after going through the troubleshooting steps we have found nothing so far. We have used the troubleshooting steps described in the following link https://rockwellautomation.custhelp.com/app/answers/detail/a_id/60178 We eventually replace the drives and after the drive is replaced there is such no fault on the drive. This makes us believe that the issue is somehow at the drive end. Could you guys provide us with help regarding some of the extra troubleshooting steps we might look for? I can provide other details as well if you require it. Thanking you all in anticipation. ### Assistant: Are you saying that after replacing the drive, the problem goes away for some time, but the new drive eventually reports the same fault? You have meggered the motor and the motor leads at 1000V? What was the resistance reading from this test? You have run the drive with the motor leads disconnected from the drive? The drive runs without reporting the fault? What is the motor lead length from drive to motor? Is there any sort of drive output conditioning (load reactor, active filter, etc.)? \n


### Human: Kinetix 6000 E36 and E72 Faults Summary: What temperatures do you see these faults?Approximately what internal temperature in a Kinetix 6000 would indicate an E36, drive converter overtemperature or an E72, drive inverter overtemperature? ### Assistant: Per the manual, the environmental operating range is 0-50C. If you're experiencing these faults at an ambient much less than 50C, check the fan & airflow through the drive. If you're close to the upper limit of ambient temperature, you may be exceeding the continuous current rating of the drive. The E36 is specifically for the converter, which may indicate that it is undersized for the inverters in the system. \n


### Human: Migrating from PFLEX 700 to 753 on PLC 5 Summary: Wanting to change from Powerflex 700 to Powerflex 753 using Remote I/OWhat would be the steps needed to take to control a Powerflex 753 on Remote IO on a a PLC 5/60? ### Assistant: Double check the logic command word that is defined for the PF700 and make sure it matches the logic command for the PF753. Technote 576280 and 65712 shows examples. Last time I did this I didn't have to make any changes in the PLC5, but I wasn't using any of the dataliniks, only stop/start/jog. Install the 20-comm-R in the 753 using a 20-comm carrier card. \n


### Human: Power Flex 755 Fault Codes 16 #204 , #926 Summary: Recommend to upgrade 755 firmware from 9.001 to 11.001. For a Network issue????Fault ### Assistant: Haven't a clue what the difference is; you could look at the firmware release notes: http://literature.rockwellautomation.com/idc/groups/literature/documents/rn/750-rn037_-en-p.pdf http://literature.rockwellautomation.com/idc/groups/literature/documents/rn/750-rn033_-en-p.pdf It very well could be they discovered a problem in 9 with memory management and fixed it in 11. I have personal experience with the early firmware releases for 755 drives running CIP motion. In version 1, the Ethernet port could only handle about 10,000 packets per second, while a simple discover query using RS-Linx could send over 30,000 packets per second. There were about 4 firmware releases in 2011 as Rockwell frantically patched serious flaws in the 755 product line. \n


### Human: Powerflex 753 Startup Issue Summary: Drive will not reach setpoint and appears to over-ampI'm having an issue with a Powerflex 753 drive that we recently installed which replaced a starter motor. The drive is 480V and 40A while the motor is 35.5A and 22kW. The motor is having problems starting when it is under a heavy load. When we try to start the motor while under load, the speed will only reach about 5 hz, the amp output is 40A, and the motor will not turn. If you decrease the load on the motor, it will run fine. The motor was able to handle the same heavy loads before we installed the VFD. Are there any parameters I can adjust to fix this? Also, the VFD never generated a fault when it was running at 5 hz even though it was commanded to 30 hz. Shouldn't I have seen an overload fault or something? ### Assistant: Was the motor nameplate data put into the proper parameters of the drive? Did you run a start-up wizard either on the drive HIM or using DriveExecutive or Connected Components Workbench software? Do you have the proper motor pole count set? Is the drive configured to be V/Hz, Sensorless vector, or Vector / open feedback? \n


### Human: Looking for a good example of speed/position stand alone master/slave for PF755 Hello, I have a customer that has an application with a dual shaft mixer where he is looking to keep the two shafts 180 degrees out of sync with one another using PF755 and absolute encoders as a stand alone application. Is there any supporting documentation for this or do you have any ideas on what would be the recommended way of approaching this. ### Assistant: The PF755 drives can do this - and technically you only need one PF755 - the other drive could be dumb as long as the master motor has encoder feedback. The slave drive would receive both the master feedback and slave feedback and do electronic gearing. However, it sounds like the 180-deg out of sync is required because the two shafts have the potential for physically interfering with each other? If this is true, you're getting into dangerous territory where it would be better to have a PLC and do CIP motion with both PF755 axes. While it's technically possible to do everything you need using devicelogix within the drive, doing all of the logic in a 1769-L18ERM CompactLogix processor is much, much, MUCH easier. So much so that the time you save easily pays for the cost of the L18ERM processor. \n


### Human: Axis Event Logging Summary: Capturing events on K6500 amplifiersA while back, I was able to download some sample code from Rockwell that captured events on K6000 (SERCOS) amplifiers. This was handy when debugging events or faults that occurred on back shifts or weekend events. Does anybody know if there is sample code like this for K6500 amplifiers? ### Assistant: I haven't seen an error logging AOI for the K6500 like the one for the K6000. The built in fault log in the axis properties should provide similar functionality though, just make sure you only execute an MAFR or MASR when a fault or shutdown condition exist. Otherwise your log will get filled up with every time you executed one of those instructions. You can also see all the faults that have occurred on a particular drive through the drive webpage. \n


### Human: PowerFlex 700 In Precharge Summary: PF 700 staying in Precharge under certain conditions.Hi all, I have a PF700 (20BD156FDAYNANCO) Frame 6 Series B that works fine most of the time. When the power gets cycled to it, it will stay in pre-charge and any residual DC bus voltage will eventually bleed off. I can't find much on the actually power structure of the drive, but from the documents I have gathered in the knowledge base it would seem that the pre-charge board needs replacing. Whenever the pre-charge board is not working, all of the LEDs are off on the board, but when the drive is functioning normally the green LED stays steady like it should. If we let the drive sit for a period of time (varys, but usually 10+ minutes), it will power up like normal. It is going to take a little time to get a board here. So in the mean time, is there anything else I can check? Thanks, DLR. ### Assistant: Just for clarification, there is an external power supply for the control voltage so the HIM is displaying the In Precharge. Someone here (the plant) thought it was a good idea for the external power supply so we would know what the drive was doing during the times it would not precharge (although, I have repeatedly asked for a precharge board to at least eliminate that component, even if it did not fix the problem). So, it has had this problem for a while now, but just hasn't received the attention it has needed due to the drive eventually working. Also, whenever I said let it sit, I mean with the power off, then turning the power on to it after a certain amount of time (doesn't matter if the external power supply is on or off during this period). Thanks, DLR \n


### Human: PF525 auto tune failure Summary: Fail to auto tune Powerflex 525Twice in the last year I have been unable to auto tune a power flex 525 in fvc mode. Encoder is A quad B differential 12vdc. Motors have been SEW and Nord inverter duty . Encoder coupled to back of motor. Oscilloscope shows good amplitude, 90 degree phase shift, and minimal ringing. Changed A and A not signals to eliminate quad check error. Even went as far as swapping A and B channels. Auto tune feature always runs motor to 44.999 hz. and will never finish. When aborting auto tune, you get the abort error. Clear it and try to run. Error codes F13 ground fault or F7 motor overload occurs. Removed motor leads from drive, metered motor with no shorts or breakdowns. Using ACVF Lapp shielded cable for motor. Shield connected at both ends. Lowered F1 kp to F3 kp from 100% to 20%. No change in outcome. Tried static tune and motor runs at high speed. After aborting static tune, and place motor in run mode, motor accelerates to extremely high speed ( much higher than 60hz). Motor nameplate data matches P31 through P37. Replaced encoder card and also replaced drive. Eventually updated the drive firmware from 4.001 to 5.001. No change in results. I have never had this problem on any other power flex drives. Spent many days trying to resolve this issue and have given up. Any thoughts would be appreciated. ### Assistant: I've had similar issues with the 525. Im guessing that the motor will run fine in SVC mode, but as soon as you put it in FVC it either faults or fails to control speed. For FVC with an encoder to work correctly a successful rotate tune must be completed. Make sure your feedback type is set to Quad Check. Also, the forward direction of the motor must match the forward direction of the encoder. Double check the directions are the same and switch A and A- if they don't match. \n

### Human: PF753 drive with safe stop hi I am using a PF753 drive for on of my projects.(20F11GD034AA0NNNNN).The control panel has a E-stop circuit present with a potential free contact. Can i program the TB1-Di2 pin as a Safe stop.Is the safe stop option module 20-750-S1 is necessary for the safe stop to work? ### Assistant: http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/750-rm001_-en-p.pdf You should read this manual carefully. The short answer is yes, you do need the card if you want a safety function. The digital input you reference can be used as a STOP, but it is not a safety stop. \n


### Human: powerflex 755 cip motion drive Summary: absolute encoderUsing Studio 5000 rev 28, Powerflex755 Cip motion drive rev.12.002 with a 20-750-UFB-1 card . I'm working on an application that uses a screw jack to raise a roller in position for a lathe. I need a recommendation for an absolute encoder to use for this application. The roll will only have to go to 2 positions. Not much resolution is needed. I have tried a fully digital SSI output encoder but Studio 5000 does not support this encoder. I would appreciate any recommendation you may have ### Assistant: The UFB module should support SSI feedback, see page 281 in Rockwell publication 750-IN001O-EN-P - October 2014. Studio shouldn't care what kind of feedback the drive uses as long at the drive supports it. You will probably need to confirm the SSI device you have is supported by the UFB. \n


### Human: 1305 replaced by Powerflex 525 Summary: Main RCD Tripping after drive replaced.Hi We have recently replaced a 1305-BA09 with a Powerflex 25B-D010N114 in an 18 year old panel, since doing this we have started to get random tripping of the main RCD in the panel. Has anyone any experience of this happening and reasons for it. Thanks Graham ### Assistant: Tell us about the motor leads. Are you using VFD cable? Is the shield landed directly on the VFD (as it should be)? Is the motor end of the shield also landed on the motor (as it should be)? Is the ground wire running back from the motor landed directly on the VFD (as it should be)? \n


### Human: Solar Water Pump Drive Summary: Solar Water Pump DriveCan I use PowerFlex drive to work as MPPT drive for solar water pumps? ### Assistant: What voltage are you planning to supply the Powerflex, and what is the voltage of your motor? Some powerflex drives will take 120V 1-phase input to run a 208V 3-phase motor. \n


### Human: Axis Status bit or data tag Summary: Motion group axis status informationHi everyone, I have configured some powerflex 755 drives in the ControlLogix program motion group. I can see that there is Status category under the Axis properties. Double click the status category and in the open window, it shows Motion status, Axis status, and Digital I/O. There are some items under Axis status, such as DC Bus up, Position Lock, standstill, etc. I try to bring the Axis Status to the HMI display. Where can I find the bit or data tag related to these status in the PLC program or manual? ### Assistant: It is <NAME OF AXIS>.DCBusUpStatus, .PositionLockStatus, .VelocityLockStatus, etc. In your case the name of the axis would be MA_TFR01. \n


### Human: Powerflex 400P Pressure application Summary: run drive at pressure setpointHello, I have been searching for some time but not finding exactly what I am looking for.

That said, a 545-amp, 450-HP drive is not the place to begin learning. I strongly suggest you acquire the services of a competent integrator or specialist. Such an integrator can help you and provide training while maintaining safety and avoiding risk of damage to your drive. \n

### Human: Kinetix 6000 drive fault Summary: Drive faulted not sure on what the bits mean in PLCWe had an MDF-SB1304F-QK82B-S motor fail on us. We replaced it and all is good. What I was wondering is that we had a drive fault and in the PLC software (RSLogix 5000 V.20) it showed a Physical Axis Fault. We found but 14 and 31 on in the AxisServo.DriveFault. Is there a table that shows what all these bits mean. I believe I found one in the help file but it shows 28-31 as reserved. Is there a table which shows which each bit means Thanks in advance ### Assistant: Rockwell publication MOTION-UM001F-EN-P, pg 212 http://literature.rockwellautomation.com/idc/groups/literature/documents/um/motion-um001_-en-p.pdf Its easier to troubleshoot the K6000 using the 7 segment display on the front of the drive, what was the error code that showed there? \n

### Human: SEW AS7W with PF755 and CIP Motion Summary: Is the AS7W compatible with PF755 and CIP Motion?I have been supplied several SEW motor gearboxes fitted with AS7W encoders instead of the expected AS7Y, they are to be used with PF755 / UFB-1 and CIP Motion. SEW has told me that the AS7W is a Hyperface encoder. I have had no luck getting it to work when Hyperface-SC is selected. Has anyone got any suggestions?

### Human: PF525 with HTL encoder Hi everbody, I want to share my story about this:PF525 with HTL encoder.We created an easy position control application with gearbox,chain and asynchronous motor with HTL type of encoder. The encoder power supply was 24VDC and the output of the A and B channel also.We wired the encoder output channel to the PF525 encoder card.The power supply comes from the cabinet control power supply.The connection of the encoder is single ended because the type of the encoder is HTL. After we wired the all components in the application,we want to test the equipment.Didnt work properly,after every move we were in bad position,compared to where it should be.We checked everything,mechanical and electrical things.We cretaed trend about Encoder speed(378) and Units Traveled H(388).We checked what happen,why were we in bad position.We have seen on the trend,we dont go with same speed and traveled units with forward and backward,even if we dont set position control,speed feedback,(simple settings)only check what happen.First of all we checked the power supply,that the supply has correctly (24VDC and common also), but it was perfect.After we checked channel A and B with oscilloscope.The signs of the encoder were perfect,without level problem.It wasnt missing signal. Fortunately the encoder can work with 9-30VDC,therefore we wired the encoder power supply to the encoder card power supply and we had set 12VDC.Because of this level also changed to 12VDC.And what a surprise the system works fine. In summary the encoder card count badly the encoder signal with 24VDC encoder power supply.This problem exists only when the drive has controlled.If we didnt control the drive the count was good.But unfortunately is not realizable:) I think the card is very sensitive of the DC level,therefore the card dropped the signal if the level is higher than maybe 26VDC.(The RA wrote this value to the card,and also wrote down,the card can handle HTL encoder) Please check your product limit before sell it!!! Regards and sorry my english knowledge ### Assistant: Hi Tom, I try to use the position control mode with Pf525 and TTL encoder connected to enocoder card. But the problem is that my drive wouldn't start. The drive has been set for position mode with step logic. I want to move the converyor belt to defined position but nothing is happening after start. The drive is in the run with 0Hz. When I run the drive with velocity mode, I can read the Encoder Speed but the Units Traveled is always very high and doesn't change while drive is running. Do you have any manual or sample code, which halps me discove how to use the position mode with pf525 with CompactLogix? I will be grateful for any advice. Cheers, Przemek \n


### Human: When drive is told to decel it stops Summary: when we tell the drive to decel it coast to a stop.I have a power flex 753 drive on a 250hp motor. The machine has been in service for 10 years, but we had a drive go bad a few weeks ago. We installed the new drive loaded the original parameter's back in, and it went back into production. We have a problem now that when you tell the drive to decel it goes to stopped. This started yesterday in the middle of production. The drive has a 110v adapter card that we send an analog input to for a speed reference. The drive shows that it is still enabled, and it is still being told to run. I am also trending the command speed with drive observer, and it is not dropping out either. I even put latch bits in the PLC to make sure that the drive commands are not blinking. The other thing I noticed is that the last stop source, and the last start source bot say pwr removed. I have looked all over for more clarification on what this means, but cant seem to find any. We are going to change the adapter card this morning, and see if that makes a difference. I am also going to hook a process meter up to the drive, and send it an analog signal just to verify the wiring. I am able to start the drive and ramp it up I can start and 30hz and ramp it up incrementally no problem. The problem only occurs when trying to slow it down. I have a breaking resistor installed as well, but the dc buss doesn't even go up. If we want to start the drive back up, then we have to cut off the start signal and turn it back on again. There is no faults or warnings on the drive, and it still shows enabled. I have included a screen shots for reference as well. I guess my question is has anyone ever had a drive do this? I have looked in knowledge base, and forums but cant seem to find anything. ### Assistant: Can you upload the drive DNO file for us to look at? \n

### Human: Ultra3K driving a LDC-C100 series Linear motor (460VAC) Summary: Motor moves only over short distance and reaches peak currentHi All, So we have this custom motor from Rockwell-LDC-C100series which is being controlled by the Ultra3K drive. The encoder we use has a 20um optical pitch with 1um resolution. The motor is mounted vertical ( we do have brakes, latches, and straps to avoid a free fall incase motor loses power etc) The total moving mass is about 50kg.The issue we are seeing is that, we are unable to travel more than 25mm ( even with low speeds of 5mm/sec) where in the current reaches its peak value (68A) and servo faults. We have checked and verified the following-U, V, W phase wiring ( using commutation test available in ultraware as well as manually trying all 6 combinations of U, V, W phases;) Hall effect sensor -S1,S2,S3 wiring ( when moving up-S1 leads S2 leads S3 and conversely lags when moving down, confirmed with physical scope as well as scope option in ultraware), encoder is reading correctly in the full length of travel. There are no mechanical parts in its path that may be causing this. Can anyone think of anything we may be missing here ? Thanks in advance. ### Assistant: Is this a brand new application you're trying to commission, or an existing installation that suddenly stopped working properly? \n


### Human: POWERFLEX 700S FAN Summary: SHOULDN'T FAN STOP WHEN VSD IS ON IDLE?Hello experts, I have got 13 (thirteen) 355kW VSDs and when they are in idle mode the cooling fans remaining running all the time. I have before worked with SIEMENS MASTERDRIVES and MICROMASTERS SIEMENS MASTERDRIVES the fan will only start when the VSD receives a start signal and stop when the VSD receives a stop from any source. SIEMENS MICROMASTER the fan will start when the VSD receives a start signal,the fan stop is user defined via parameter. Does the POWERFLEX 700S frame 10 have that option? Any parameter or hard wiring ? Please see the attached name plate. ### Assistant: Take a look at the technote below https://rockwellautomation.custhelp.com/app/answers/detail/a_id/28186/page/2 tech note:28186 Question When do the heatsink cooling fans turn on or run in PowerFlex 700/700H and 700S AC drives? Environment 20B PowerFlex 700 / Reliance SP600 20C PowerFlex 700H 20D PowerFlex 700S Answer The heatsink cooling fans turn on or run in PowerFlex 700/700H and 700S AC drives as described in the list of frame sizes and cooling fan operations for each below: PowerFlex 700 / SP600 Frames 0-4 On newer firmware (approximately mid '07) the heatsink cooling fan will be running only when the drive is modulating PWM (running). So when the drive is powered up and in a stopped state the heatsink cooling fans are off. In firmware before mid '07, the heatsink cooling fan will be running when the drive is powered up. So when the drive is powered up and in a stopped state the heatsink cooling fans are running. PowerFlex 700 / SP600 Frame 5-6, 8 The heatsink cooling fans are powered from the line or utility power. This makes the heatsink cooling fan on as long as power is applied to the drive. This is why you must use input terminals R and S in single-phase applications for these frame drives. For DC input drives you must supply 120VAC or 240VAC to power the fans. The frame 5 requires 100VA. Frame 6 requires 138VA. PowerFlex 700S Frames 9-14 The cooling fans come on after precharge and remain on until power is removed. They are AC motors powered by small inverters that are powered by the DC Bus. The ASIC board sends a signal to the inverters to start after precharge. PowerFlex 700H Firmware Revision 4.001 or Less All fans will run once the drive exits precharge PowerFlex 700H firmware version 5.001 or greater The heatsink fan will run when the drive is modulating (running). The fan will turn off when the drive is stopped and the heatsink temperature is below 55C for 60 sec's. Fan Control Option Added The ability to turn off the main cooling fans under certain conditions has been added. For 480V AC / 650V DC drives, when the drive is stopped and the heatsink temperature has dropped below the limit of 55° C for 60 seconds the cooling fans will turn off. Also, for 690V AC / 932V DC drives, when the DC bus voltage drops below 1000V, the cooling fans will turn off after a four minute delay. If this functionality is not enabled, the fans run whenever the drive is energized. The following parameter has been added to support this new feature. Parameter 465 [Fan Control] The ASIC card fan will run when the drive exits precharge. \n


### Human: PowerFlex 525 with a SEW CMP71M servo drive Summary: Need parameter for PowerFlex 525I would like to operate a PF 525 with a servo drive from SEW(CMP71M) Has anyone ever done this? What parameters do I need to enter? Möchte am PF 525 einen Servomotor von SEW (CMP71M) betreiben. Hat das schon mal jemand gemacht? Welche Parameter muss ich da eingeben? ### Assistant: I do not think this will work. The CMP71M motor has either resolver feedback or HIPERFACE feedback; you did not give us a complete part number to determine which. The 525 only takes incremental encoder feedback by adding an option card. If you are fixed on using the CMP71M motor, you would have to go with a Powerflex 750 drive with the 20-750-UFB universal feedback board. That feedback board will take HIPERFACE feedback. \n


### Human: Single Isolation Transformer Multiple VFDs Summary: Has anyone ever use one big isolation tranformer to feed a panel with multiple VFDs?I have a panel with 11 1HP, 2 3HP, and 1 15HP PF525 drives and I want to use one isolation transformer to protect the power grid from the harmonics generated by the VFDs. I don't have room for individual line reactors and I'm not worried about protecting the drives from noise on the grid. Has anyone ever tried this? Would I just add up the KW ratings of all the drives? ### Assistant: i have done it with large drives and I did add up the KVA of each drive. you may also want to consider whether or not all drives are on at the same time etc. so that you may be able to get away with a smaller xfmr. keep in mind that even with an isolation xfmr the harmonics will still be quite high for six pulse diode front end drives. MTE and Arteche make some passive as well as active harmonic filters that should get you down to the 5% THD range. \n

### Human: Servos and kinetix 6500 Summary: Problems with motion of servos and kinetix 6500Good morning, I have 4 kinetix 6500 and 4 servos MPM-B1653C-MJ74AA. I have them all on stopped status, and i am using Motion Direct Commands to move them, but i'm having several problems with them. The MDC that I use when in stopped status are: MSO->Goes to Running Status->MAM->Starts moving with an incredible intense noise (like if its stopped by the breaks at least partially)->MAS->It stops the motion, but the noise stills and even more intense->MSF (the noise dissapears and goes to Stopped) That is the same for the 4, but each has particular problems: servo1: This one can move, stop, and change speed(fast and slow), even though the intense noise is there (and varies depending on speed and accel/decel) but with less than 5 min of use, it was super hot and finally an overtemp error appear. servo2: with the same speed the first one did well, this one does not. with very little speed it can moves a little bit, but eventually an S55 error appears (excessive velocity error) servo3: when it starts moving, in about 10 seconds maximum, it appears the FLT S13 and FLT S14 (inverter thermal overload factory limit / inverter thermal overload user limit), and also appeared the S55 error servo4: much like servo3 Any tips would be greatly appreciated Andres ### Assistant: Have you performed a polarity check and an autotune on each of the axes? You must do these two things before you can use an axis. It also sounds like you have polarity problems with wiring for both power and feedback cables. Before performing the polarity test and autotune, THOROUGHLY examine the power wiring connections and feedback connections. Are these Rockwell cables, or cables made by a third party such as Igus or Lapp? I have encountered one instance where a third-party cable was incorrectly made and caused us several days of down-time while we traced it. You must check each termination that you made. A crossed wire on the motor power cable can cause the results you've described. A crossed wire on the feedback terminations at the drive could also do this. \n


### Human: Memory module in Kinetix 300 and Kinetix 350 Hello, I read in the manuals the following: ### Assistant: Hello, I have a doubt about the following issues: 1-The parameters loaded automatically to Kinetix 350 from RS Logix 5000, What is the function of the memory module in Kinetix 350 in this case? 2-Is the function of the memory module in Kinetix 300 is to save the parameters only? 3-Can we Run Kinetix 300 or Kinetix 350 without memory module? 4-If we replace the damaged Kinetix 300 or Kinetix 350 with a new one with the same type and put the old memory modules in them, To run the normal operation need to perform any thing in the new drives? Please explain Thank you in advance. \n


### Human: PF750 drive keep decelerating status not stopped when stop command issues A PF750 drive with 20F11NC085JA0NNNNN. When stop command issues, drive ramp to zero ,but drive continue to keep decelerating status but not stopped. When restart command issue, the drive cannot start. The drive is connected with digital input for start and stop, no communication. When power off and on , the status indicator cleared. ### Assistant: What motor control mode (parameter 35) are you using? Did you enter the motor nameplate data correctly (parameters 25, 26, 27, 28, 29, 30, and 31)? Did you perform an autotune? Static or rotating? What is the current value for Autotune (parameter 70)? What is the value for Slip RPM (parameter 621)? \n


### Human: PF 753 No HIM Response We have a PF 753 that has over heated several times the past few weeks becasue the cabinet a/c unit quit working. I have not been able to power up the drive after the last incident. When power is cycled, the HIM starts to boot up but never makes it past the screen that says Allen Bradley when first turned on. Any ideas? ### Assistant: If you look at the status LED next to the HIM, it is most likely flashing orange, maybe in a repetitive code (x number of flashes, pause, repeat). I cannot find any documentation what the blink codes mean, but ANY orange blinking is not good. You can try removing and properly reseating the HIM, but most likely the main control board is dead and must be replaced. If you have multiple PF753 drives, you can try swapping in a known good one to be sure it is just the main control board. The part number for a replacement PF753 main control board is: SK-R1-MCB1-PF753 \n


### Human: PowerFlex 523 Seria A x Serie B Analog Input An OEM was building air compressors using Powerflex 523 Serie A with a Pressure Transducer 4-20mA (2 wire) as a PID feedback connected to pins 11 (+24VDC) and 15 (4-20mA input). Now with Series B is connecting to 11 (24VDC) and 13 (Analog Input) but it is not working. It seems like Common from 24VDC power supply is not connected to the analog circuit. Any suggestion? Regards, Daniel ### Assistant: Not sure if you have solved this, but if you ground term 14 to term 4 (digital common) it seems to work. \n


### Human: CONVEYOR BELT DRIVE GEARBOXES JERKING Summary: CONVEYOR BELT DRIVE GEARBOXES JERKINGHello, I have a set of 4x250kW flange motors coupled to gearboxes (two motors are sharing a shaft to turn a pulley) which will drive a 1.5km conveyor belt that carries 3000t/h of coal. Now my problem is that the gearboxes has just developed a jerking up and down movement should we run at +45Hz but all along it has been stable. What could be the problems,encoder or parameters on the POWERFLEX 700S? Note; I used LEINE LINDE XHI 861108956 Part number 750729-12 on a POWERFLEX 700s 355kW ### Assistant: Why do you think the problem lies with the encoder or the drive parameters if the system has been stable until now? If the system WAS stable at 45 Hz but is not now, that sounds like the load has changed and is causing a resonance at that frequency. I would look for a mechanical problem, something that has increased friction along the conveyor length. If NOTHING else has changed, there should be no reason to look at drive parameters. It's possible the encoder could be giving problems, but you would encounter it at more than just one specific frequency. \n


### Human: Cannot connect to 1756-L71 We have a setup which consist of 11 drives on DLR connected to EN2TR controlled by L71(V20) . Everything works fine but as soon as all the drives are switched OFF i am not able to connect to the controller and the controller basically hangs up .. i can see the chassis in rslinx but when i browse the chassis and try to connect to processor it does not connect and wait a very long time .. Also changing key switch from run to program also doesnt help . The programming device is also connected in the same DLR .. basically the setup is EN2TR to ETAP .. ETAP to drive 1.. drive11 -- EN2TR in DLR and i am connected to device port of ETAP .. As mentioned above i can see the chassis in rslinx but when i browse and try to connect it in logix i cant Any suggestion on what could be cause ??? ### Assistant: Which device is the DLR supervisor, the PLC or the ETAP? Have you tried opening the ring between the EN2TR and drive 11 so that the setup is a line, and then shutting down the drives? \n


### Human: servo drive 2198 H025-ERS Summary: servo drive AOPHi I have some issues on the AOP installation. I have a drive 2198 H025-ERS. I tired to installed AOP and eds file. But after that, I found I need Major Version 7. I only have version 1-5 I am using Studio5000 V29.01 Where can I found a correct one AOP Did I miss anything ? Please help me on that. Thanks ### Assistant: Go to the Product Compatibility / Download Center (PCDC) http://compatibility.rockwellautomation.com/Pages/home.aspx Click on FIND DOWNLOADS Put AOP in the search box You can also put Kinetix 5500 in the search term. Then click the DOWNLOADS button \n


### Human: Power Flex 753 - Change output relay configuration of Fault Summary: In the parameters of RO0 output from port 4, I want to set fault state of parameter 935, but it does not give me the option.How can the relay output of a PowerFlex 753 I/O module in port 4 be programmed to change state based the fault status of the drive? What status parameter would you link to monitor the relay output to change. In the parameters of RO0 output from port 4, I want to set fault state of parameter 935, but it does not give me the option. ### Assistant: If you go to slot 4, parameter 10, that is the place you configure the R0 output. The first thing you have to set is what port will provide the information. You need to set port 0, the drive itself, to get drive fault. Then you select which parameter of port 0. For your situation, you pick 935, Drive Status. Finally, you pick bit 7 - Drive Faulted. I think you missed setting port 0. If you set the port to 4 (the IO card itself, you don't get the configuration you want. Setting it to port 0 does. Let us know if this worked. \n


### Human: power flex 525 Summary: skip frequency I set parameter a449 to 30hz and a449 to 3hz, and yet my drive does not skip but accelerates right through my skip frequency. I tried a450 and a452 but no difference, ideas? ### Assistant: In your post, your first A449 you actually mean A448, correct? Skip frequency means the drive will not run at that frequency. If you've set A448 to be 30 hz, A449 to be 3 hz, then the drive will not run in the window between 27 hz and 33 hz. If you were to try to set the run frequency to 30, the drive would go to 26 or 34 hz. Look at page 120 of the user's manual: http://literature.rockwellautomation.com/idc/groups/literature/documents/um/520-um001_-en-e.pdf From your initial post, the drive is doing exactly what you are telling it to do: don't operate at 30hz. What are you trying to achieve? \n


### Human: 1394 turbo system losing program I have a 1394 drive controller that has lost its parameters a couple of times when the power was off for a couple of weeks. This had never happened before a month ago, but now looks like it is going to get to be a regular issue. I looked over the controller and didn't see an obvious battery. Can I correctly assume that these drives use a capacitor for memory retention? ### Assistant: What parameters in particular are lost - all of them or just some? Could it be that these are being written to by an external device and the 1394 not losing the data? If its the battery, then the data must be stored in a different type of memory from the application program, otherwise you would lose that as well. The following is from the KB on the subject (Ans ID 27691). The following isn't what you want to read - so need to be sure its the battery thats causing your issues. BATRAM KEY FEATURES 10 years minimum data retention in the absence of external power Data is automatically protected during power loss Unlimited write cycles Low-power CMOS Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time Summary: The battery back up RAM (batram) for the 1394 GMC & 1394 GMC Turbo is NOT field replaceable, the unit MUST be sent in for repair. The batram is a self-contained lithium energy source and control circuitry. Catalog Number: 1394 GMC;1394 GMC Turbo DocFullNum: G73448994 \n


### Human: PF 400 output frequency problem Summary: drive is not running on commanded frequencyCustomer have power flex 400 Ac Drive, 125Hp. They are using it for Agitator application. For first 12 hour they run drive on 25 Hz its working ok, After that they run it at 50Hz but in this condition drive output frequency automatically reduce from 50 hz to 43 Hz. observed commanded frequency is 50 Hz, output current decreses when output freq decreases. I have already told them to increase the current limit 1 and 2 and disable, drive OL mode parameter. WHAT ELSE CAN BE DONE TO OVERCOME THIS ISSUE ? NEED YOUR SUGGESTIONS. Thanks ### Assistant: What value is set in parameter A175 (Slip Frequency)? Try setting this to value 0. Is there a non-zero value set in parameter A188, A190, A192 (skip frequencies)? Set them back to zero if so. \n


### Human: Power flex70 fault code F511 Summary: Fault code F511I would like to know about power flex 70 Fault code F511? For the system we use controlnet communication (20ComC) and config this port is ( 5 ). Cat no.of power flex is 20A5P0A0AYNANC0 For this code we can't reset ### Assistant: According to the 20-COMM-C manual, page 199 http://literature.rockwellautomation.com/idc/groups/literature/documents/um/20comm-um003_-en-p.pdf event 11 means Another peripheral with the same port number is already in use. Do you have another option card installed? \n


### Human: PF527 MAG Instruction without Encoders? Summary: Wonder if a PF527 without encoders can still use a MAG instructionAs the Title and Summary state. I'm looking to doing a velocity synchronization application between a Main Conveyor Motor and Take-up Conveyor Motor. I know the PF527 supports the MAG instruction, but does the drive need to have an encoder connected? I'm familiar with the use of servo instructions and Kinetix Drives, but this would be my first use of a PF527. I've looked for examples but couldn't find any. any help/direction is appreciated. Regards Vin ### Assistant: I've done simple MAJ instructions on a PF755 set up for vector control, open feedback. MAG, almost by definition, wants encoder feedback to synchronise the slave to the master. I think the results without it would be rather poor at best, if not flat out impossible to do. Are both motors on the same conveyor, one supporting the other? Or are they two different conveyors? If it's two motors on one conveyor belt, you could set the slave drive to be a torque-follower and not need feedback on it. \n


### Human: PowerFlex 40P Downgrade Summary: downgrade from 3.01 to 2.01Hello, we want to downgrade a drive PowerFlex 40P from Firmware 3.01 to 2.01. Our machines are using drives with 2.01. Last Time a 40P was defect we installed a drive with 3.01. After that we had massive problems in cause of the mismatch from firmware. We tried to disable Keying-> didn't work. We are using ControlFlash. Is it possible to downgrade? ### Assistant: According to this knowledgebase article: https://rockwellautomation.custhelp.com/app/answers/detail/a_id/42454/page/1 Users like us cannot change the firmware of Powerflex 40P drives. You have to send the drive back to Rockwell to have it changed, or hire Rockwell to come on site to do it for you. Sorry, you're out of luck there. You're going to have to figure out ways around the changes caused by the firmware. What processor is choking on the changed firmware? \n


### Human: kinetix 5500 - Demo box 120 VAC Hi, Can a kinetix 5500 be wired to 120 VAC for demo testing? Thanks, Thomas ### Assistant: The smallest K5500 drive shows a standard input of 195-264 VAC, single phase. It MIGHT work on 120, but I suggest you put a single-phase 120-240 step-up transformer into your demo box. The 2198-H003-ERS draws a nominal .7A with single-phase input, 2.1A peak. A 750VA transformer would suit this application. A Sola E750E weighs 31 lbs. If you're careful with your demo and stay away from peak loads, you could get away with a 500VA transformer; the Sola E500E weighs 19 lbs. \n


### Human: Variable frequency drive energy saving calculator Summary: Variable frequency drive energy saving calculatorcan anyone please provide me the excel sheet in which I can calculate the energy saved by adopting the variable frequency drive for the Blower in sewage treatment plant for 120HP motor. ### Assistant: Contact your Rockwell distributor - this is something that sales group should be jumping all over in order to sell you VFDs. \n


### Human: PF 400 output current fluctuations Summary: pf400 output current is fluctuation too muchhoping all you are doing great. here is new the problem, PF 400 3-phase 25Hp drive is having issue. in telephonic discussion with site person he told me that there are total 7 drives out of which 2 drives is having issues. these drives are connected with motor and motor is coupled with load via Belt system. Load is FAN and application is blower. drives are working fine when load is uncoupled with motor. Issue is that during operation current fluctuations can be observed from 15 amps to 45 amps and motor is producing too much noise. I already told them to set basic motor parameters and to increase PWM frequency from 4khz to 6khz but it wasn't making much difference. also compensation mode to set at both(electrical and mechanical) sometimes drive is also faulting at F7. accl dcl time is above 50sec. boost select is at 0.0 no IR, what else can be done to overcome this issue. regards. ### Assistant: Is this a new installation, or have they been running normally for some time and the problem suddenly cropped up? What is the nameplate data for the motor? What is the exact part number for the PF400 drive? All 7 systems are identical, but 2 do not function correctly. What is different about those 2? Are the belts tensioned in the same manner as the other 5, and tensioned to the same amount? Do the fans spin freely by hand (is there something wrong with the bearings)? Many questions, but they all need to be answered to diagnose this problem. \n


### Human: PowerFlex 525 in closed loop control (PID) Summary: basic controls and frequency Hi guys, I need t control an AC with PF525 to rotate clockwise or counterclockwise to maintain a certain position given by an analog sensor (like an auto balanced system) I used a PID to control the speed 0..60Hz depending on analog sensor position. How can I drive the outputs to rotate forward and reverse according to the sensor? PS. if I use the PID to give dpeed output from -60Hz...60Hz, should it rotate according to the frequency sign? ### Assistant: Yes, it should. However, it gets weird if your analog signal is 4-20ma. For you to be at zero-speed, the analog signal has to be 12ma. Not difficult, just not quite intuitive. If your signal is -10v to +10v, 0V is zero-speed. In this instance, an analog voltage signal is more intuitive (and probably safer). \n


### Human: PF755 AOI, issue with Datalinks Summary: PF755, ND 100HP V13.3, connected to L45S v20 over EthernetI am configuring a PF755 on a v20 Compact Logic L45S. The PLC is just doing basic Start/Stop/Speed for a large Fan. I'm using AB's AOI and faceplate for ME. The issue I'm having is the last 3 default input Datalinks from the AOI configuration are not available on the drive that I have (Parameters, 951-LastFaultCode, 11-DCBusVolts and 7-OutputCurrent) are there appropriate substitutes for these parameters. I was looking and nothing popped out at me. See attached image for reference. Regards, Vin ### Assistant: You're saying that when you configure the datalinks IN THE DRIVE, those parameters are not available? Are you sure you're looking at the correct port on the drive? Any chance you're looking at an option port instead of port zero? \n

### Human: 2093-AM02 Summary: Current limitIs it within the capability of this 3KW control amp to set a current limit for the output? Using a 1.8KW motor and 5:1 reducer to power an Exlar FTX125 actuator that has an input torque of 46Nm. Based on the data sheet, the MPL A330 motor will produce 11Nm of peak stall torque resulting in 55Nm torque at the input to the actuator. Can we limit the current to the motor? ### Assistant: Open the AXIS properties (not the drive), and go to the LIMITS tab. There are check boxes to enable hard and soft travel limits, numeric entries for position error, and at the bottom numeric entries to set peak torque limit and continuous torque limit. You can also issue an SSV command to the axis to configure continuous torque limit, as well as TorqueLimitBipolar, TorqueLimitPostive, and TorqueLimitNegative. \n


### Human: PowerFlex 523 and external input supply I'm controlling a PF523 with 2-wire control using external power from a PLC output card. Can I still connect terminal 11 to terminal 1 on the drive? (leave the jumper in). Since terminal 11 and the external power supply have the same common, would it still work? ### Assistant: Yes. As long as the drive's terminal 4 common is connected to the external supply's common, you are good to go. Connection examples can be found in the 520 user's manual: http://literature.rockwellautomation.com/idc/groups/literature/documents/um/520-um001_-en-e.pdf \n


### Human: PF 400 Faults Summary: PowerFlex 400 Overcurrent and Ground Fault on Start CommandI have around 60 PowerFlex 400 drives running and most run perfect. On about 20 of the drives, I regularly get either an overcurrent fault, a ground fault, or both as soon as I send a start command. I clear the fault and the drive starts and runs fine. Sometimes the drive will start without faulting. I'm using a 30 second ramp start. Any ideas? ### Assistant: http://literature.rockwellautomation.com/idc/groups/literature/documents/um/22c-um001_-en-e.pdf Take a look at page 18 of the user's manual link above. It discusses the phase-to-ground jumper for ungrounded systems. You haven't told us what frame sizes you're using or if your system is solidly grounded or not. This might be one source of the problem. It also might be the distance of the motors from the drives - how long are the T-leads from drive to motor? \n


### Human: Converting from Hyperface to standard encoder. Summary: Kinetix 6500I am looking to convert one of our machines from a Hyperface feedback to a standard 1024 Incremental encoder, and wanted to know if I change the interpolation and the counts in the feedback properties would anything thing else needed to be changed also? Thanks, ### Assistant: You're changing from an MPL type motor down to a TL or TLY motor? I think you've covered the places that need to change. \n


### Human: Powerflex 700 Summary: external stop switchGood morning everyone, I am looking to see how I can go about wiring an external stop switch to cut off my powerflex 700 after a set amount of time (2-4 hours). There seems to be no way to do this from the inverter so can you externally wire a stop switch? Any help would be greatly appreciated. Best regards, Shane ### Assistant: http://literature.rockwellautomation.com/idc/groups/literature/documents/td/20b-td001_-en-p.pdf Go to page 44 and 45 of the PDF link above. It shows the control board terminals for the various versions of PF700 drive (you haven't told us what exactly you have). Near the bottom of each of the three tables you will find the digital inputs. If yours have not been repurposed to something else, digital input #1 on all of them is STOP by default. The same information is given at this link: http://literature.rockwellautomation.com/idc/groups/literature/documents/in/20b-in019_-en-p.pdf starting at page 54. Page 57 shows how to wire 3-wire control including a stop button. If you use a time delay-off relay, you should get the function you're looking for. \n


### Human: allen-bradely 1332 vfd 1 to 3ph Summary: can the vfd output 3ph out of 1ph?Hi, I own an allen-brdley 1332 CAN variable frequency drive. The unit is rated 380VAC and 5hp. It is main purpose is to change the frequency of a three phase input. I read in some forums though, that all vfd's can output 3 phases pout of one, with only a drawback of fallen horsepower. I also see in the manual of the 1332, that specifically the 230VAC units can output 3phases out of one. My purpose is, since i do not have access to 3 phase power in my current lab, to create it out of the 230VAC. I understand that the 1332 cannot step up the voltage given in it, so my though would be to use a transformer to output 380VAC. The motor i want to drive is 1,1hp. Are these units known to work at such a level? Would it be safe for the unit to try to input 380VAC one phase to test the output or may i damage the unit? any help appreciated ### Assistant: What manual I could find on line does not reference 1332 drives rated at 380VAC. They reference 230, 460, and 575V drives. The manual I found does say THOSE 1332 drives can take single-phase input. That said, I would not simply presume all 1332 drives can take single-phase input. Contact Rockwell Technical Support and see if they better documentation than I've been able to find on line; this one has a publication date of 1987. \n

When i try to coonect to the unit i keep getting an error code STS 0x2.. Can someone tell me what is the error code is, or what my problem is. ### Assistant: A USB converter can be used, however, you need to assign it to one of these 4 ports: COM 1, 2, 3 or 4 on the machine.

### Human: Suggestion for a servo motor required to connect to rockwell servo Summary: Selection of a suitable servo motorHi, I want to connect a suitable Rockwell servo motor to a Rockwell drive system. The PLC used by my customer is AB PLC L36ERM. I want to connect a suitable Rockwell servo motor to this. The torque requirements are very less. The mechanicals comprise of a linear timing belt and carriage. At present we use a stepper motor with a max holding torque of 101 Ncm. Anything more than this would also be suitable. Could anyone suggest which motor would be suitable? thanks arun ### Assistant: You've given very few facts with which to size a servo system. You've only given us a processor model, so you could use a K350 or a K5500 economically. But you've not said anything about voltage so no one could recommend more than that. You've given only torque, you've said nothing about the necessary speed. You've told us the type of mechanical setup, but nothing at all about reduction ratios, load, inertia, friction, cycle time, etc. You need to give us a LOT more information if you want useful recommendations from us. I suggest you use Rockwell's Motion Analyzer: https://motionanalyzer.rockwellautomation.com/ \n


### Human: MDAC, MAG OR MAPC Summary: Length calculation with External encoderThe issue I have is the external encoder rides on the material that is driven by the servo drive. Another programmer closed the position loop and modified tuning parameters for the kinetix 7000 when using the external encoder and when using the motor encoder he moves a different set of tuning parameters into the drive. My customer doesn't want to have to change the encoder used when the material runs off of the external encoder. Since the encoder is driven by the material, and the material is driven by the servo, I am having a had time figuring out the best solution to use. Can I use a MAG, MAPC, or MDAC since the material isn't driven by a secondary source? Is there a better option than what is currently being done? ### Assistant: JC, I don't think you have a lot of options. Tying the external encoder to you servo axis (by either Load or Dual feedback modes) will have issues when the encoder runs off of the material. How do you detect when the material runs off now? Is it a run-to-length process or just measurement? This is the closest example to your application, however, what it describes can't be done on-the-fly. https://rockwellautomation.custhelp.com/app/answers/detail/a_id/550046 Jeremy \n


### Human: PF 527 no frequency output for forward Summary: powerflex 527problem : motor can running reverse but not forward with command what i did: change a new drive , same problem. use motion command to run motor both direction is running. when i give a command to run reverse , everything is good , voltage , frequency , current. But when given a forward command i can see command and speed was given to AOI for PF527 , but no voltage and frequency output .i replace 2 new drive they all same . somebody can help me ? ### Assistant: You need to give us a lot more information for us to help. The best thing you can do right now is upload your PLC's ACD file for us to look at. It's most likely an axis configuration problem of some sort. It doesn't make sense for us to guess at it; uploading the ACD will get you a good answer rapidly. \n


### Human: PowerFlex 700 Size 6, Heatsink OvrTemp Summary: Does this drive have fans?Lately we have been encountering the Heatsink OvrTemp fault on our PowerFlex 700 Size 6 drive. If there are fans they are not visible from the anywhere. It started out happing after around 20 minutes of run time and now it happens around 10 to 12 minutes. The heat sink is getting hot and we can cool it with air and the unit runs fine for longer times. I just don't want to pull it apart and not find any fans and we aren't going to spend $15000 to replace this unit just for a couple of fans. Are there Fans on this unit? If so, where are they located? Has anyone attempted to replace their fans? ### Assistant: Yes, it does have fans. http://literature.rockwellautomation.com/idc/groups/literature/documents/um/20b-um002_-en-p.pdf Fault 8 on page 87 refers to your exact problem. Also look at the technical data document: http://literature.rockwellautomation.com/idc/groups/literature/documents/td/20b-td001_-en-p.pdf There's the installation document: http://literature.rockwellautomation.com/idc/groups/literature/documents/in/20b-in019_-en-p.pdf Unfortunately, Rockwell does not have a service / maintenance manual for PF700, as stated in this article: https://rockwellautomation.custhelp.com/app/answers/detail/a_id/535148 From your description, I would say the fan is no longer spinning. You should check the fan wiring (see the installation document), and verify that it is in fact spinning. They're not quiet; it should be very obvious if the fan is running. \n


### Human: PF525 Control Module Replacement Summary: Need to replace PF525 Control module with a different HP controllerWe have an issue that we did not have any same size drives in stock to replace a drive with an F110 fault. I was trying to take the parameter from a 10HP 460VAC drive and download to a 1HP 460VAC drive controller. Tried using CCW, handheld HIM and USB utility for PF525. Kept getting errors on the downloads and the parameters would not change from the 1HP settings. Was not able to manually enter the parameters for the 10 HP. The drive is also EthernetIP connected. I saw in various places that the Control module of the PF525s were interchangeable. Is there a procedure to do this update using a different control module from a different size drive? ### Assistant: nan \n


### Human: Drive example apps? I'm trying to learn this new powerflex stuff and I learn best when I have example apps. (Manuals put me to sleep! :) ) Anyone have a good link to drive example apps? ### Assistant: Have you looked at the sample code library? There are examples there that show how to do drive control with ControlLogix. You can find it here http://samplecode.rockwellautomation.com Hope that helps! Cal \n


### Human: Elements required to action an specific cylinder electric. Summary: I am going to make a project about position control with a cylinder MPAR- A3800E-M2BGood Morning everyone. This is elementary to know, but I would like to know Which are the elements that I need to activate an MP series Cylinder (MPAR- A3800E-M2B) Including Control, control motion, software, etc. For this type of Cylinder. Thank you. ### Assistant: Julio, this is too sweeping a request for a user-supported forum. You need a drive, Logix Designer (and then pick which firmware version), some form of communications card (Ethernet, SERCOS), cables. This is the sort of question you need to ask your local Rockwell distributor and local Rockwell representative. They should be knocking down your door to assist you in specifying Rockwell products. If they are not, then ask us here; I'd be happy to recommend mine. \n


### Human: PF 700s Phase II unicast/multicast support in RSLogix v18 I replaced a PF 700s Phase II drive and Logix is returning an I/O error that says it doesn't support unicast/multicast data. The old drive was firmware version 4.001 and the new one is version 4.002. Otherwise, everything is the same. I used the 20-COMM-E from the old drive and have kept all the parameters the same. Is there something I missed or something I can change to fix this? ### Assistant: Hi, and welcome to the Forum ! Please, post the EXACT error message, or better a screenshot... it will be easier for Forum users to start a research on it. Also please post some informations about your Ethernet/IP network, configuration, Switches, IP address, modules used, 20-COMM-E firmware.... ...all what you can add to clarify things could help in trying to solve. :smileywink: - fuzzy logic \n


### Human: Mam error code Summary: err 05mam err 05 means what? who meet this and solution, thanks! ### Assistant: with this little infromation you should not expect any reply \n


### Human: Powerflex 755 - Input Module Explosion Summary: Issues involving the performance of the new Powerflex 755- productsGood Morning, I came here to find more information or suggestions regarding the last issue that we had in our plant. We have five Powerflex 75HP drives running pulp pumps. The electrical room has HVAC and optimal temperature and humidity conditions. Last week we had a sudden failure in one of the powerflex 700 drives, it had been in service for more than four years, and we haven't had any events during its normal operation. We began doing an extensive inspection and we found a hotspot in one of the modules, and one of the IGBTs were damaged. So far it was an isolated event but during last week we have two additional explosions of two new powerflex 755 drives. The whole rectifier module was damaged, and we guess it has something to do with the pre-charge circuit. We have lost three drives and we want to make sure that our installation is reliable. The typical installation scheme for our plant includes the input circuit breaker an output contactor and reactance. We did an extensive inspection of the ground scheme with no issues. We only found no PE-B jumper installed on the drives but we don´t think this has something related to the input module failure. What do you suggest?. How do you improve the MTTF of our drives (typical 3- 5 years ). ? Did anyone had a similar experience?. What did you install to reduce the probability of a sudden failure?. Does the new family powerflex 755 demand more from the installation in comparison with the powerflex 700 drives. Thank you for your comments or suggestions, Best Regards, Daniel Riascos. ### Assistant: If your supply is solidly grounded, then both the PE-A and PE-B jumpers should be installed. If it is not solidly grounded, then both jumpers should be removed. Rockwell has NEVER been able to adequately explain why they ship drives in an indeterminate state with one jumper installed and one removed. It's both IN, or both OUT, according to Rockwell's own literature. It just doesn't make sense. The jumper configuration could play a role in your failures. The output contactor is a different problem. Is there any chance the contactor opened while the drive was still running? If the contactor opens before the drive is disabled, you could blow up the drive. You must make sure the drive run command is removed before opening the output contactor. You would do better to move the contactor to the input side of the drive, or better yet use safe-torque-off option card and eliminate the output contactor entirely. \n


### Human: Adding a timer to Powerflex 525 for maintenance intervals Summary: We want to track pump run timeWe want to add a timer to the pump ran by the Power Flex 525 that is controlling a Roots blower, Any ideas? ### Assistant: Parameter B019 in the basic display group is elapsed run time. You don't have to add anything at all; the drive keeps track. If you require an external elapsed time meter, the 525 has two relay outputs. Relay 2 on terminals R5 and R6 is already configured to be a running indicator (parameter T081 is set to value 2). If you need the opposite contact, then program relay 1 on terminals R1 and R2 to be the running indicator by setting parameter T076 to value 2. \n


### Human: Physical axis fault Summary: 1756-HYD02 physical axis faulthaving a physical axis fault. built an automatic fault reset and placed a counter on a oneshot on it. the counter will count as many as 100 resets at a time. happens when the axis is almost fully retracted and not every time. ### Assistant: Sounds like the position tolerance of the axis but could also be related to gains or tuning. Just a few ideas. Shane Welcher \n


### Human: Powerflex 700s Fault 27 ( IOC ) Intermittent trip Morning all! Hope to get some answers on this re-occuring fault that has us baffled. We have a powerflex700s as the lead drive on a front drum of a winder and are currently experiencing intermittent Fault27 ( Instantaneous Overcurrent ) trips. This drive has been on line for several years without issues but, for the last 8 months, it has been faulting on F27. We have done the following to isolate the problem yet it still trips and appears the frequency of trips is more often. 1.)Swapped drive to spare and downloaded running program. 2.) Autotune3.) Changed Motor4.) Temporary motor cable swap5.) Temporary tach cable swap6.) Lowered parameter 402 from 900 to 300 - PWM Bandwidth We have attempted to run an autotune, and believe to have done so successfully but still trips. We suspect tuning may help us but unsure where to go from here. Any suggestions, correct answers and I'll buy coffee? Regards, Thibs ### Assistant: first thing the manual says is reduce mechanical load...how did that affect it? \n
