### Human: How to plan the PF400 drives to MODBUS networks and Remote HIMS? I have a question for PF400 drives applications. 4 pieces of PF400 drives is set to MODBUS networks and evey drive has a remote HIM on cabinet. But PF400 drive has one RJ45 port. And I know we have a spiliter cable(master/Slave) to connect the RJ45, and the spilitter ports ,one for Master and the other for Slave. Can I use the splitter cable to support my idea( One for Remote HIM and the other for MODBUS network)? ### Assistant: HI BUDDY YOU DON,T NEED TO USE SPLITTER CABLE FOR THIS PURPOSE AS YOU CAN DIRECTLY USE RJ45 CABLE FOR REMOTE HIM AND FOR MODBUS COMMUNICATION (22-COMM-H) YOU CAN USE DPI PORT 5.DPI PORT 5 IS LOCATED ON THE DRIVE YOU CAN REFER USER MANUAL FOR THAT. HOPE THIS ANSWERS YOUR QUESTION.BBYE \n


### Human: 1756-M02AS Axis Feedback Problems We have a control logix system, using version 13.04. We have a MTS temposonic linear probe that we have connected to a 1756-M02AS card and using feedback only for a display of the position. This works great until the power is removed from the control logix rack for whatever reason, whether it be power outage or turning the power off. When the power is removed and then turned back on we have to cycle the power that goes to the MTS temposonic probe, after we do this it works great again. The part number on this MTS probe is RPM0420UD701S1B6102. We have other MTS probes in use on other machines and don't have this problem. I have contact AB with this problem and they tell me it is a problem with the MTS probe and I need to contact MTS. So I contacted MTS and they tell me that the problem is with the device that we are using to read the feedback. Has anyone ever had this problem? Is there something we could do in the logic to simulate the same thing, like at the first scan or something? Thanks for any help. ### Assistant: Do you have any error Status on the Axis when the Fault occurs? Have you tried using the MAFR (Motion Axis Fault Reset) in Direct Mode? Possible Workaround is to use the MDO function and the Enable for that Axis to Power the MTS \n


### Human: Speed Regulation Mode Summary: Speed Regulation Mode in laymans termCan some explain in laymans term on this explanation by A-B. I can't get a good grasp on this. Speed Regulation Mode In a speed regulated application, the torque reference is generated by the speed regulator output. Note that under steady state conditions the speed feedback is steady while the torque reference is a constantly adjusting signal. This is required to maintain the desired speed. At transient state, the torque reference will change dramatically to compensate for a speed change. A short duration change in speed is the result of increasing or decreasing the load very rapidly. TY.. ### Assistant: Selecting speed regulation mode means you want to maintain whatever speed you set. In order to maintain speed, torque will fluctuate as necessary to hold your set speed. The opposite is true if you select torque regulation mode. To maintain a constant torque, the speed will fluctuate as necessary to hold your set torque. \n


### Human: 1336F-b050 Drive Summary: stop drive after 20 minutesWe would like to stop drive after 20 minutes. But this drive is in a stand alone system connected to the pump itself. It has a HIM display, but no TB3 board. What I was going to do is add a timing relay inside and remove the enable after 20 minutes. So here is my question, can the drive have both an HIM (start command and speed control) and a TB3 board? Use start button on the HIM, it would stop 20 minutes later when I removed the enable. Cat ### Assistant: I would set up the TB3 as a '3-wire' configuration and hold the STOP input true, then interrupt it when you need to stop. You could do the same with the Enable input too. As long as the TB3 doesn't have any exclusive control features programmed (like 2-wire mode, or Local Control) then you can use it to assert a STOP only. STOP is asserted when it is provided by any interface to the drive and cannot be masked out. The -L6 on the end of the part number indicates that there was (when it was delivered from the factory) a 115V AC version of the TB3 discrete input board installed. \n

### Human: PF700S I am looking for example programs for the PF700s drive. This application is speed matching two machine sections using two PF 700s 7.5 hp drives with synchlink. The application is a bottling machine with a filler section and a sealer (capper) section, the two sections are not physically connected and they have separate motors and encoder feedback. I want to use one drive (filler) as the master with two encoder boards installed one feedback from each section motor encoder and slave the sealer thru synchlink. ### Assistant: Hello, An application engineer has provided this DOC file that might help \n


### Human: Baud rate for 20-750-CNETC connected to PF753 Hi, In some manuals, I see the communication specification attached below. So,if a 20-750-CNETC option connected to PF753 DPI port is selected for ControlNet communication, I can only get the maxium baud rate is 500K, but not 5M max.? Is it right? ### Assistant: On the Network side, the protocol is ControlNet, which only runs at 5 Mb/s. On the Drive side, the protocol is DPI and the data rate is 500 kb/s. Don't think of every bit on the Network corresponding with every bit on the Drive; ControlNet supports 99 nodes and hundreds of meters of cable and a wide variety of devices, while DPI is a tiny network that runs a few inches of ribbon cable between the drive, the HIM module, and the 20-Comm-X. In general I estimate a 10 millisecond delay between a packet arriving at the 20-COMMx and the drive taking action on the command in that packet. I know the 750 series are faster than the 700 series and you can ask RA for specifics, but that rule of thumb has always proved good enough for me. \n


### Human: Powerflex 700 fault 121 I am experienceing this fault and did a search of the forum and found this, but it was left unresolved. http://forums.rockwellautomation.com/t5/forums/forumtopicpage/board-id/Drives/message-id/2212 . I was wanting to see if anyone has found a resolution to this fault. I have replaced all components in the VFD, then replaced the VFD. I am still getting the fault occasionally. Any ideas on what to check next? ### Assistant: We went into the VFD bucket, MCC and also the motor and tightened all of the ground connections. This seems to have fixed it. \n


### Human: PowerFlex40 Regenerative Load Summary: What (if any) is the regenerative load passed to the incoming AC LineMy application is powered using a generator. The end user is concerned that the drive will pass the regenerative load back to the generator causing problems with the generator's voltage regulator. The equipment is Powerflex40 with line reactor and external dynamic brake. (There are three motors which are all set up the same (motors are 1.5 HP (2) and 1.0 HP (1)). What is the regenerative load that could be passed back to the generator and (if present) how can it be limited? ### Assistant: The front end of the PF40 drive is diode so there is no way to get the regen back onto the line. The bigger problem with running a drive on a generator is the non-linear load. The drive does not draw current from the source through the entire sinewave of the incoming voltage. This causes voltage and current distortion. Basically it comes down to the generator needs to be oversized for the load. What is the load that it will have regen? This drive will handle some regen, but it is not the best drive for a lot of regen. It can have problems with bus regulation. \n


### Human: PF 400 tripping in Undervoltage Fault Summary: Fault Code 4In our Plant Cooler section we have 13 nos. PF 400 Drives ( Cat No. 22C-D260A103 132 KW MFD 2007 JUL 30 China). Out of them 3 Drives are often (After 2-3 day’s) tripping in UNDER VOLTAGE FAULT F4. After every fault i have checked Advance Display Parameter d326 Fault Bus Voltage which was 560-580 VDC (Normal) I have enabled Flying Start & Bus regulation parameter but problem not rectified. Any Suggestion PLZ ? ### Assistant: Are there any line reactors installed with the drives? With this many large drives together there's a good chance the harmonics cresated could be causing DC bus ripple, which the drive could interpret as an undervoltage condition. Cheers \n


### Human: How to Programm kinetix 300 with RSLogix 5000 How do I have du Programm a Kinetix 300 Drive with RSLogix 5000? I use a MPL-A310 Servo and want to use my Kinetix with a Logix5561. How do I have to configure the axis in RSLogix for Ethernet/IP? I am new to Rockwell and Allen-Bradley I only used Siemens SIMATIC device for projects.

### Human: 20 COMM D FW VERSION Summary: ERRORS WHEN CHANGING 20 COMM D MODULE WITH DIFFERENT FIRMWARE ### Assistant: I'm getting some faults related to PORT 5 adapter on a PF70 with device net adapter 20 COMM D, so after troubleshooting it I decided to change 20 COMM D comms adapter, the one that is installed is a 20 COMM D FW VER 1.007 Ser B and I have a new one FW VER 2.001 Ser B, after installing the new one and downloading the config to it a new fault rise and I wasn't able to clear it, the fault was related to config parameters. When I downloaded the config to this new adapter the HIM asked me for confirmation telling that this was a different version to that I hited the enter button accepting the warning. Then after a cuple os seconds of resetting everything the fault appeared. I put again the old module with no faults. Do I need to have the same FW version to replace the 20 COMM D module? Any help will be must welcome. \n


### Human: Kinetix 300 Standalone Summary: Using Kinetix 300 with two Anorad linear actuators.Hi I'm quite new to this kind of automation components and is therefore seeking a little help. I'm working on a project where I'm supposed to control numerous actuating parts, where one is a Kinetix 300 servo drive controlling two Anorad linear actuators. The actuators are two function as a XY-table in robot cell. I've not received any components yet, so all I have to go on are the datasheets available online. The entire system will be controlled from LabVIEW, which brings me to my problem. I want to control the Kinetix 300 drive with TCP/IP, but I can't find out what I'm supposed to send to it. The examples I've seen require me to have a MicroLogix 1400 controller and some other components, but I am only to receive a Kinetix 300 and two Anorads linears actuators built into a XY-table. As far as I can work out I need to run the preinstalled software for the servo drive to recognize the actuators and their current load. Once it is set up I want to control the XY-table by sending simple commands to the Kinetix 300 drive. Does anybody have any experience with this? In essence what I want to do is to control both position and speed of the XY-table, by simple commands depending on the rest of the system. Best Regards Kristoffer M.Sc. ### Assistant: Kristoffer, I may be missing something, but I think you have a problem with a single K300 and two actuators. Do you plan to use a contactor to switch from one actuator to the other? The K300 typically controls a single servo motor. In the configuration you describe (xy table), you would need a K300 for each actuator. Yes, you would initially run the software built into the K300 (a java app that downloads to your computer automatically when you access the drive with a web browser of proper vintage). The drive communicates using Ethernet/IP, which is not the same thing as TCP/IP. You're correct, it is geared towards communicating via Ethernet/IP with a Contrologix or Micrologix platform. It CAN stand alone if you wish to issue descrete move commands through its digital IO (binary coding the inputs to select various indexes). That does not sound like it will work if you wish an XY table though. \n

Please take a look to User Manual chapter 1, you will find informations and wiring examples for either internal or external power source. \n


### Human: PowerFlex 750 as CIP drives Summary: Using Powerflex 750 drives as CIP Integrated motion drives Has anyone had any experience using a 755 drive, 20-750-UFB-1 card and a SSI encoder? I cannot get the Logix PLC to configure the drive in a usable way. ### Assistant: I have! I have! Getting the settings right required several calls to Tech Support. We had some weirdness occur with getting the drive to configure, I think having to do with one person trying to configure the drive on the network while another was upgrading the firmware on a bunch of Armorblock IO modules. Bad combination; the drive could not handle the RS-WHO calls (40,000 per second, or some such nonsense), and would CIP-SYNC fault. Rockwell has since released a firmware upgrade to fix that. There was much confusion too because Rockwell documentation talks about Channel A and B in the Logix5000 IO tree, but X & Y for the UFB card. It DOES work, but you'll have to give more details for me to be of useful help. \n


### Human: mitigate electromagnetic noise Summary: electromagnetic noise Do you have experience with VFD installed close to electronic equipment, e.g. inside MCC cell or control board? What are the measures taken to avoid or mitigate electromagnetic noise? Do you know of a specific publication or whitepaper on installation inside control cabinets as with VFD next to DeviceNet controller in MCC? Any information will be appreciated. Regards, Moshe Marlov ### Assistant: One of the best out there is: http://literature.rockwellautomation.com/idc/groups/literature/documents/in/drives-in001_-en-p.pdf Publication DRIVES-IN001K-EN-P It should be the starting point, however, supplementary filtering might be needed.

ABB hardware includes EMI filters within their latest generation ACS800 AC drives. \n


### Human: PM 3000 Modbus TCP Can anyone tell me how to communicate with modbus TCP on 1404-M405? Is it with the -ENT option, or is there another for modbus TCP? ### Assistant: PM3000 -ENT option only support Ethernet/IP protocol, there aren't other options for Modbus TCP (see screenshot)... :smileysad: In order to do this communication, you need a gateway standalone module, like these: http://www.anybus.com/products/products.asp?PID=371&ProdType=Anybus%20X-gatewayhttp://www.prosoft-technology.com/content/view/full/7366 Maybe useful the link to the Encompass site, where you may find out all these solutions and others. http://www.ab.com/db/encompass/bps_ext.search Hope this helps… - fuzzy logic \n


### Human: Self Sensing - Ultra5000 Hello, I have an Ultra5000 drive (2098-IPD-20) and I need it to drive a Moog AC servo motor. The Moog had a resolver so we put a quadrature encoder instead (A+, A-, B+,B-, I+,I-) and wanted to use the self sensing ability of the Ultra500 to automatically determine the commutation. No matter what I define in the drive I keep getting error 39. The motor STARTS rotating and after a couple of seconds it faults out putting error 39. I really don't know what's the problem....? The motor parameters are properly defined and I do see in the Ultraware the encoder counting when I rotate the shaft manually. Any ideas? Thanks,Dan ### Assistant: Anybody? Dan \n

### Human: Kinetix 300 Estop Condition I have a Kinetix 300 and a MPL motor. I am connected to the drive via a Micrologix 1400. My problem is that once I resume from an Estop condition, I want to be able to push a button and have the drive go to a fixed position. However, the drive wants to continue to run the 1st index. After multiple attempts to abort the index via messaging, it still wants to run the 1st index. Even if the servo is running the 2nd index when the Estop is pressed, it wants to return and run the first index. Has anyone been able to find a way around this? I would love to be able to just push a button and have the drive go to a fixed position. ### Assistant: nan \n


### Human: powerflex 700 error code:F902, what is reason? ### Assistant: Fault code 902 = Fatal Motor Overrun Possible communication issue or fault between Power Board and Control Board. This is a development fault code that is not part of the normal fault listing to this drive. The recommended procedure is to replace the Control Cassette if problem persist. I strongly suggest to contact the Technical Support for your region, asking about the error code. - fuzzy logic \n


### Human: 1336 plus II him status display I have several 1336 plus II's, and on one of them the status display on the hmi is not backlit. Call me picky or whatever, but I just want all my drives to look alike. I tore through the user manual twice and still can't find anything to help me. I came here before the knowledgebase so now that's where I'm going.Thanks ### Assistant: Did you try the HIM on another 1336 Plus II? Or another HIM on that drive where the display is dark?Just to better understand where the problem is.... seems to be a faulty HIM, or some other component in the drive, like HIM connector, or board that doesn't give enough power to it. \n


### Human: 230 vac to a PF 40P drive Summary: 230vac 1 phase power into the PF40P or PF40 running a 230vac 3 phase motor.I have an application that there is a need to run a 3 phase 230vac motor with only 230vac 1phase power available. I would like to use the PF 40P but I dont see an opton for it. If it can be done what is the derating for the drive to do it? If it cant be done with a PF 40P can it be done with a PF 40 or anything else? ### Assistant: Powerflex 4x three-phase input drives can be run using single phase input, providing a 65% derate of drive rated current.

### Human: SERIES A Drive Cat No. 22A-DP0N104 Summary: Under VoltageHi, I have a client who currently used this kind of Drive: Cat No. 22A-DP0N104 SERIES A Motor Rating: 1.5Kw/2.0HP Input: 3 Phase, 380-480V, 46-63Hz AC Voltage Range: 342-528V Amps: 5.7A Output: 3phase, 0-240Hz Ac Voltage Range: 0-460 Continuous Amps: 4.0 60 Sec Ovld Amps: 6.0 My question is: 1) If the incoming voltage is 380V, can this type of inverter run in healthy condition? 2) What will be happening if the voltage reaches below 380V? 3) What is the minimum voltages for this inverter? 4) Will the amps (input/output) increase if the voltage decrease(below 400V)? 5) What does it mean by 'AC Voltage Range: 342-528V' ? Regards, Aziz ### Assistant: The specs are fairly straight forward. The inverter will run normally if you are able to maintain the voltage anywhere within 342-528V. The inverter takes that 3-phase input voltage, converts it to DC voltage (approximately 1.4 times the AC voltage). It then chops the DC voltage up to simulate an AC signal out to the motor. To answer your questions: 1) This inverter can easily run on 380V. 2) The data sheet says you will get a bus-undervoltage fault if the DC bus voltage drops to around 390Vdc, equivalent to about 275Vac line input voltage. That's a pretty significant sag if the nominal voltage you expect to give it is 380. I would try to keep the input voltage above the recommended 342Vac, but you do have a good margin. 3) I'd treat 342 as the minimum, but you can go lower without causing a bus-undervoltage fault. 4) You'd likely see a larger current draw, but if you size your overcurrent protective devices according to the specifications given in the datasheet for the drive, you should not see any problems. 5) We've covered the lower end of the voltage range. If you supply this drive with any voltage that is between these two limits, the drive will operate as expected. 480Vac is a common voltage. This AC input will give a DC bus voltage of 672V. This is well within the operating range. The drive will report a bus overvoltage if it reaches 810V (about 575 Vac input). NOTE: The drive uses the DC bus for regeneration when slowing the motor and load down. If a drive is running at the higher end of the ac input range, and slowig a heavy load down, the energy put back into the DC bus could cause it to fault with a bus over-voltage. From the theme of you questions though, I don't think you'll be working at the higher range. TJ McDermott \n


### Human: Powerflex 40 3-wire run command Summary: Does run/forward command have to be maintained?On a pf40 using 3-wire wiring configuration and internal +24vdc, does the run/forward command have to be maintained or just momentary? ### Assistant: In a 3 wire control, the Start command act as a Momentary Input; Stop Input must be maintained to let the motor run. You may clearly understand the wiring inside Chapter 1 of the User Manual (1-20 and 1-21) - fuzzy logic \n


### Human: Harmonic Filter with PowerFlex700 drives Summary: Use one Harmonic Filter with multiple PowerFlex700 drives Hello dears, I am designing a RO system which we are using almost 15 PF700 drives (11KW=10 and 5.5KW=5) in same MCC room. I want to use single Harmonic filter (Low Pass) with all VFDs. My two questions as below 1- Harmonic filter for the PF700 required or not required to meet the IEEE-519 standard (according to the IEEE-519 it should be 5-8%)? 2- One Harmonic filter with 15 VFDs is workable or not? Please advice accordingly. ### Assistant: You need to use an Active harmonic filter for multiple drives, remember to also use a input choke on each drive. This will reduce the active filter size. A complete harmonic analysis is required to size the unit. You need the KVA / fault rating and impedance of the supply transformer, cable lengths and the amount of linear load on the same feeder. Here is a link to a calculator tool http://webdc.transim.com/rockwell/ If all the drives are operating at the same time then just add the kw's as one large drive \n


### Human: 4160 VFD Summary: Synchronous Transfer ProblemsWe have a 4160 synchronous transfer bypass system for two motors that will not synchronize with the fixed frequency buss to allow the transfer. ANy thaught on where to start looking? Could it be the isolation transformer? ### Assistant: Wow !! I guess this is with Powerflex7000 drives, best to leave it to the experts and get a Rockwell field support engineer involved \n


### Human: Frequent Motor Starting I have a case conveyor application that requires frequent starting/stopping of a 1/2 HP squirrel cage motor at 10 times per minute. (3 seconds on - 3 seconds off). I am concerned that if I use a NEMA starter for this application that it will beat itself to death within a year or so. Would a SMC soft starter be able to handle this frequent start/stop application? ### Assistant: I have used a freq drive for similar applications. I would consider using a fan cooled inverter duty motor. Have an application where we are starting and stopping a 2hp motor 30 to 40 times a minute, been running 6 years. \n


### Human: Screen saver on HMI of Powerflex 70 / 700 Summary: Can we setup Screen saver on HMI of Powerflex 70 / 700? The HMI of Powerflex 70 / 700 happens to be in the MCC room & the display is continuously ON, for months together. HMI is seldom used once the setup is done & the respective machines are running normally. The backlit display goes off at times or display screen becomes dim, may be due to continuously powered ON. Can we setup Screen saver on HMI of Powerflex 70 / 700 like on our PC so that the display will be OFF if the HMI is not used for set time & comes ON when we start using it.? ### Assistant: nan \n


### Human: Powerflex 755 Speed Synch I have an application in which two motor speeds need to be synchronized under varying loads. One motor is a 30HP and the other is 10HP. The 30HP is the master and carries the bulk of the load. The 10HP should run at the same speed as the master to assist with load. Each motor has a 1024ppr encoder on the shaft. The application could be described as a conveyor with a motor on the head and tail pullys. If the speed is not sych'ed the belt either bunches up or stretches. I think gearing would be the best solution in this case? If I wire each encoder to it's drive for closed loop vector control, do I need a splitter to send the master signal to the slave? Can the master signal be wired to two drives without splitter device? It would be really neat if that connection (feedback) could be done over EIP? ### Assistant: If you do Ethernet/IP connections from PLC to drives, and your PLC is a controllogix, and your ethernet adapter for controllogix is an EN2TR or EN3TR, then you can do CIP motion and easily do what you're looking for (right, lots of ifs there). I have CIP motion in one application, but have been struggling with unexplained faults that reqiure drive-power cycling to clear. I'm not totally prepared to endorse CIP motion, but it's close. \n


### Human: Powerflex70-Enter RPM on display Summary: type in RPM on the HMI to make the motor run that RPMHi All, I am currently using a Powerflex70 equipped with a HMI full numeric keypad. What I am looking to do is be able to type in 1500RPM on the HMI keypad and then hit start which will run the motor at 1500RPM. Any idea if this is possible ? Thanks for any input ! ### Assistant: The instructions to do this are available on the rockwell Knowledge base Doc 21005 - Change the Powerflex70 Display to show RPM \n


### Human: Multi Motor application with Powerflex 755 In our standard application we normaly use a 45kW drive for 6 or 7 5.5kW Motors. Now we have a application with 18 1.8kW Motors (--> 32.4kW)We want to use also a 45kW Drive and standard 5% Output Line reactor (1321-3Rxx)Cable length per Motor is maximum 10 Meters. You think it could cause a problem to connect so many motors on one drive? ### Assistant: As long as your motors are all the same, you shouldn't have any problems provided they don't exceed the rating of the drive. In a textile plant that made nylon fibers, we had plug panels that were fed from different inverters. Each plug panel served 32 motors. If a particular recipe called for a certain speed on the winders, we would just plug the winders into the appropriate plug panel from the inverter running that specific frequency and turned it on. We only had 4 frequencies the motor ran at anyway which made it possible to run multiple products from one spinning application. \n


### Human: CIP Motion and PF755 Summary: How many here have encountered problems with CIP Motion and PF755I've a persistant, sporadic, irritating problem with two PF755 drives running under CIP motion. Tech Support is working the problem but have not yet found a conclusive problem. I've already contacted Vong and dwalserams about their problem posted here: http://forums.rockwellautomation.com/posts/8242c929e2 I am VERY interested in talking with anyone else who encounters problems with PF755 drives running under CIP Motion. Please feel free to respond here, or call if you wish. Sincerely, TJ McDermott Systems Interface 425-750-1629 (Pacific Time Zone) ### Assistant: Update: Rockwell sent a specialist to collect data on this problem. Luckily, the anomaly manifested while he was on site. Testing required a special, temporary firmware be installed in the two drives. This firmware provided access to additional parameters, one of which was the number of communication buffers in use in the drive. This buffer count is supposed to be zero, occasionally rising as low priority communication is deferred until the drive can handle them. We discovered that the buffer count will sometimes not go back to zero. Hitting the drive with web page accesses can really spike the count, but it eventually drops back down. Some sort of message from the network gets stuck in the buffer and doesn't get out. The count increases, until it gets close to 50. Upon reaching 50, the drive stops communicating via Linx. Cycling power to the drive resets the buffer count. So, we now know WHAT is happening, but not WHY. Regardless, the PF755 in CIP motion has a firmware problem that must be fixed; some message is getting stuck in the buffer and prevents anything that went in previous to it from getting back out of the buffer. Or, the buffer index is being messed up. Whatever, the drive doesn't handle all messages properly. The brute-force fix we're going to implement in the mean time is to add an additional 1756-EN2TR module to communicate directly to the two drives in this system. I know there are other PF755 CIP motion problems; it does feel like the 755 is a bit fragile compared to the Kinetix 6500 in CIP motion. Has anyone else had problems with PF755 in CIP motion? Any problem at all? \n


### Human: CIP Module Fault - 755/53 & EN3TR Getting random module sync faults that can only be reset by completely powering down the drive. Only thing on the EN3TR network is drives and an HMI. Anyone else have this problem? Don't seem to have the issue with the Kinetix 6500 drives on the same network, just the PowerFlex. ### Assistant: We are having the same issues. We are very interested in speaking with you about it. You can reach me at 360-281-3263. Thanks, Dan \n


### Human: ultra 3000 sercos loosing enable Summary: loosing enable signal and no faultsI have a client with 4 drives on Sercos. all 4 drives have same hard wired enable signal. Drive ### Assistant: Are you running this via ControlLogix and RS5000? You could use the trending tool (a software scope) to track a number of tags associated with the drive to see what might be dropping it out. \n


### Human: PowerFlex 70 Drive Parameters Is there a way to extract the drive parameters from a powerflex drive that is connect to a PLC5 processor by RIO? I know Drive Executive is not an option but wanted to see if there was another way other than manually recording them. ### Assistant: Unfortunately, no way.... :smileysad: You need to connect to the drive via DPI port.... - fuzzy logic \n


### Human: Ultra 100 I replaced a Ultra 100 drive (firmware 1.36) with another Ultra 100 drive (firmware 1.37) and keep getting a e-stop condition on the Sercos motion control card in the slc500. Put the old drive back in and the fault went away. Question...do the firmware versions have to be the same? I downloaded all the parameters from the old drive to the new drive with no problem. Or is something wrong harware wise with the new drive (the new drive is used but was checked out for good condition. ### Assistant: First off this is not a SERCOs system. Neither the SLC nor the Ultra100 support SERCOs. I am guessing that this is a HSRV servo control card for the SLC. The E-Stop condition you are getting is coming from the hardwire E-Stop input on the HSRV card. This sometimes has a drive fault contact in series with other E-Stop devices. If you did not get any warnings when downloading, then it should be fine to go from 1.36 to 1.37 so I would check the relay output of the drive. You could also check the settings for the IO between the two drives to make sure they match after the download was completed. \n


### Human: Powerflex 4/40 RFI Filter I am installing a PowerFlex 4 5 horsepower drive at 480v, I also have a 22-RF012-BL filter for it and I am curious if I can use this filter on the load side of the drive. I wanted a load filter and thought that is what myself and my rep had picked out but the sheet that came with the filter says that it is an input filter. Any thoughts? ### Assistant: Hi, That filter is only for the input side, do not connect it to the output. you may be able to exchange it for a 1321-RWR device which is a reflected wave reduction filter (if that is what you are looking for). Here is a link to a PDF about reactors and output filters (RWR): http://literature.rockwellautomation.com/idc/groups/literature/documents/td/1321-td001_-en-p.pdf \n


### Human: STEP Files Does RA provide .stp files of their components. I would like to use 4983-DC120-03.If I had the solid model, it would be very easy to incorporate the part into my (PRO-E) design. The dwg, dxf, & pdf options under the drawings tab don't help me. ### Assistant: As far as I know, the .stp files are only available for Motors... anyway, you may want to try to ask RAISE support team and see if they may help... Technote 40706 contains phone and e-mail address. Hope this helps, - fuzzy logic \n


### Human: Powerflex700VC Output Current Summary: Powerflex700VC Output Current still present after stoppingIs this a normal phenomenon that the time I give a stop command to my VFD I can see that the “Output Frequency” is Zero, but I still get an ‘Output Current” and at the same time the VFD is also showing “At Speed” displays on the HIM. It will take for about 3 to 4secs before ‘Output Current” goes to “Zero” and the “At Speed” change to “Stopped”. VFD deceleration time is set 5secs. I am having a PowerFlex700VC drive, 400V, 56A with a 20-CommD adapter. What I understand (maybe I’m wrong) is that when you give a stop command to the VFD after the deceleration time set elapse the VFD will shut down it circuits immediately and goes OFF. Thanks, hope someone could enlighten me. ### Assistant: I don't thinl it's normal. Perhaps it is only a display problem. You can measure the current with an clamp and see if the indication on HIM is real. \n


### Human: PF 400 Fan & Pump Ratings Summary: Trying to understand the different drive ratingsGreetings all, I recently sold a 10hp and 2 x 15hp 208V PF400 Fan & Pump drives only to have my customer come back and tell me that I have undersized the drives. The motor FLA's are 32.7A and 47.8A respectively. Their case is that even though the part numbers on the drive indicate that they drives are 33A and 49A output capable, however in the technical data guide, in the F&P section it states the drives have a 30.8A and 46.2A output. My question is, how is this possible? See clips of the two ratings below. Please help. Standard Drive Rating F & P Drive Rating ### Assistant: I believe the numbers you're looking at are on page 37, which are for configured drives. Did you sell these as configured or just open type stand-alone drives? \n


### Human: Powerflex 4 two drives one external pot Summary: Controlling two Powerflex 4 drives with one external pot Hello, We are replacing two Danfoss drives that are using one external pot to control the speed of both. They are on conveyors and one feeds the other. Is this possible with two Powerflex 4 drives? If so, what would be the wiring arrangement. Thank you for your time. ### Assistant: Yes, This is possible see attached picture \n


### Human: can multiple 753 safe torque-off modules be connected and maintain the safety function Has anyone cascaded multiple 753 drives thru the 20-750-s safe torque off module. Can this be done ? I have a customer who would like to use 1 safety output to control 16- 753 drives ,he wants to maintain a cat3 rating. Thanks John ### Assistant: You should be able to parallel the signal from a safety relay output to the 20-750-S modules. The returns would also then be tied together as well. TJ McDermott \n


### Human: Changing GML Turbo communication Hi all, I've here a GML Turbo whichhas a communication by RIO with the PLC-5 processor.We gone change the PLC-5 for a L35 compact-logix, and need to change the communication to DH-485. I've readed the 900 page manual of GML, but can't find any instruction to setup a DH-485 communication.Can anyone help with a step by step instruction, or a template GML program that is already running with a DH-485 communication? Thanks in advance! Jack ### Assistant: Never done personally....I suggest to review the 1394 User Manual page 4-13 and Appendix A-13 and the GML Commander Reference Manual starting from page 56. Hope this helps… - fuzzy logic \n


### Human: Motion Arm Watch (MAW) I have a piece of equipment that is currently using a MAW instruction to time time a dispensing valve to axis motion. The instruction suggests that the arm is useful for syncing operations to a specified axis position. The position is watched at the servo update rate (very fast) but the the problem is that the logic scan time that is waiting for the WatchEventStatus to be true could be very slow. Is this instruction any better than comparing the .ActualPosition to a certain value. I mean after all, the coarse update rate is the fastest you can expect anything to be read in logic anyways. So why is this instructin even used. The ActualPosition is coming in at the coarse update rate anyways and this is the same time you will see the WatchEventStatus change state as well. I wanted to make sure I understand this instruction and why the original programmer may have used it this way. Thanks in advance for any feedback or advice. ### Assistant: The MAW would be used to trigger an Event Task. The event task interrupts regular scanning when the MAW triggers and executes the Event task. \n


### Human: What's the function of IAM and AM. Summary: Thay both are axis module,so what is the difference?Could you expalain what of their function.It seems to be difficult to find some detailed doc. to focus on it. ### Assistant: The AM Axis Module has connections on the front for motor, encoder, and auxilliary IO. It draws its power from the power rail. The IAM Integrated Axis Module, in addition to the connections noted above, has connections for input power and control power. The IAM has the converter which takes input AC and turns it into the common bus DC used by all the modules. There must always be an IAM on the left side of the power rail. And before you say it, I agree with you, Rockwell could have picked a more descriptive, intuitive name for the IAM. TJ McDermott \n


### Human: Could you explain to me what of fuction is about registration swith? Summary: I want to know why we need registration swith? Could you pls expalin to me ? thank you very much ### Assistant: I mean I don't know what is registration switch for? anybody can help expalain to me? Thanks \n


### Human: Usage of Single VFD (Power flex 750) for two Different Motor Applications Summary: Usage of Single VFD (Power flex 750) for two Different Motor ApplicationsIn One of My Project, I have two different Motors Applications. I want to control both the Motors with the Single VFD (Power Flex 750), since both the application are having same expected Performance Characteristics and both are operating at different Timings without any time overlap. I do have one contractor panel to switch between one motor Circuit to another motor circuit How feasible to use this technique? Please let me know is there anything need to be taken care while designing this concept ? Thanks, Mani ### Assistant: I believe this scenario could be implemented only if the two motors are identical and the VFD Load side switching contactors are mechanically interlocked and operated while the VFD is passive. The VFD running application needs to know the motor's nameplate data first and then the field application's requirements. \n


### Human: coping parameter from a powerflex to be stored on a pc Summary: I need to be able to store drive parameters on my pc networkWe have over 400 differant powerflex drives from 4 to 700s We need to be able to back up the parameters so we can use the copycat function to reinstall the parameters when a drive fails and settings can not be recovered. ### Assistant: http://ab.rockwellautomation.com/Drives/Software/9303-DriveTools-SP \n


### Human: PowerFlex 750 Series VFD, DriveLogix, and PanelView Plus Summary: Looking to see if the PowerFlex 750 series VFD can directly communicate with any type of PanelView Plus HMI.We are investigating the use of DriveLogix in a PowerFlex 750 series VFD. We will be using both Discrete and Analog I/O boards. We want to have a PanelView Plus HMI (Component, Standard, or PV+ 6) interface with the VFD and DriveLogix probably over Ethernet/IP, but that’s still up in the air. Does anyone know if this possible and if so where can I find documentation or maybe some examples? ### Assistant: I don't believe you will be able to develop and run a FTV application without a CPU controller such as DriveLogix. And DriveLogix is not offered but an option for the PF700S Phase II VFD series only; PF753(750) offers the DeviceLogix option which is a configurable, embedded I/O interface. If a 5730DriveLogix EtherNet/IP option is chosen with a PF700S Phase II VFD, then you could develop and run your FTV(ME/SE) application on the subnet bridged by the DriveLogix EtherNet/IP interface. http://literature.rockwellautomation.com/idc/groups/literature/documents/um/20d-um003_-en-p.pdf For the HMI application: http://literature.rockwellautomation.com/idc/groups/literature/documents/um/viewme-um004_-en-e.pdf \n


### Human: E91 Watchdog Timer Error on Kinetix 300 I have a couple of MPL motors setup (using Modified code from the Rockwell Sample code SMC_ENETIP_ML1400_K300_2AXIS_V1_0.rss) It works great, Micrologix 1400 1766-L32AWAA Kinetix 300 2097-V34PR3 >>>> MPL-B310P-MJ72AA Kinetix 300 2097-V34PR6 >>>> MPL-B4560F-MJ72AA Now I want to setup another machine, but I want to use different IP address. I changed String: ST199:0 From 192.168.1.5 to 192.168.3.229 ST199:1 From 192.168.1.6 to 192.168.3.230 ST199:2 From 192.168.1.7 to 192.168.3.231 Once I do this the RIX201 Tables seem to populate with all of the correct IP addresses. I think that I have changed everything correctly, but I keep getting an Error on the Kinetix drive: The Error that I get is: E91 user watchdog has timed out. I get the error on both drives, and when I log onto the drives using the MotionView software, I can't clear the Error Any suggestions on where to look? ### Assistant: I think that the problem was in my PLC File. We found out that N197:11 had a value of 408 , and N197:23 also had a 408 value. Those integer files are supposed to toggle on and off from 0 to 1 so that the controller knows that it has communication. I manually entered in a value of 1 and then they started going back and forth from 1 to 0 and the E91 error went away. \n


### Human: PF753 APPLICATION CAN WINDER APPLICATION IS POSSIBLE USING DEVICELOGIX IN PF750 SERIES ? WITHOUT PLC.................. ### Assistant: It Depends on the application. Need much more information. So my answer would be a great big MAYBE? \n


### Human: ArmorStart 284D Summary: Wiring Diagram I am working with the 284D armorstart and am wondering where to find a internal wiriing diagram for the unit. I specifically I want to know where the control power wires go inside the ArmorStart. The OEM that did the hardware layout did not follow the pin outs for this cable. In the 284D manual it says + - 24 vdc are on pins 1 & 2. The OEM connected it to 5 and 2. thanks ### Assistant: The OEM was right. Pins 5 and 2 connect to A1 and A2 inside the drive, you need 24VDC between them in order to run the drive. The attached diagram might clear things up. \n


### Human: 755 in gearing application Summary: Parameters necessary for electronic gearing, has anyone used a 755 for electronic gearing the information that i have found at this point is conflicting. ### Assistant: Yeah, it is, isn't it? Is the electronic gearing occurring in the drive, or is the drive connected to a Logix platform and is being controlled via CIP motion? TJ McDermott \n


### Human: PowerFlex drives over ControlNet? I know PowerFlex runs over Ethernet. What about ControlNet? (And if it does, any problems to watch for?) I've got a customer that has a nearly religious conviction against ehternet as a control protocol... ;) ### Assistant: Yes, the powerflex dives have an adapter 20-comm-c and 22-comm-c depending on what drive you have to operate on controlnet. In my opinion it is just as easy as ethernet to setup. Just have to schedule the network once configured. \n


### Human: Battery for Powerflex 753 755 real time clock Summary: Information about the battery for this function of the drive The Powerflex 753 and 755 have a clock on board that can be set to current time, but does not maintain it through a power cycle. There is provision to install a CR1220 battery on the main control board of each drive, but other than that, there is not much more about this feature. Some details I learned today from an on-line chat with Tech Support: The battery can be expected to last about 10 years. It is used only when the drive is not powered. If the real time clock is set, and then power is cycled, one of two things will happen: If the battery is installed, the clock will maintain its setting through the power cycle. If the battery is flat or not installed, event 206 will be logged. Tech support thinks this is an alarm (not a fault). https://rockwellautomation.custhelp.com/app/answers/detail/a_id/110309 The link above is a knowledgebase article about how to install the battery.

### Human: How many members use CIP motion with Powerflex 755 drives? Summary: Not getting a response to my original question, so maybe there are not may usersI originally asked if anyone had difficulties with Powerflex 755 drives when using CIP motion. So far no one has responded to that question. So, I'll turn it around. How many members are successfully using CIP motion with Powerflex 755 drives? ### Assistant: We do, but what is the purpose of your question? \n


### Human: torque current Gidday. How can i relate the torque current to mechanical torque available at the motor shaft ? Cheers ### Assistant: it is approximate. you should have some parameters torque demand, or actual torque those would be pretty close to the torque at the shaft of the motor.... this would be 0 to 100%, it is proportional to 0 to Full Torque of the motor at base speed... if you are trying to do an application that requires torque control or driving to a specific torque you should reword the question to be more detailed. \n


### Human: CamProfile .status = 3 on loss of power Summary: There was a loss of power during a MAPC instruction in process. The MAPC Cam Profile tag[0] .status was left at 3 instead of 2. What is the meaning of the cam profile . status codes? How are they reset? This status of 3 instead of 2is keeping my MCCP from running. ### Assistant: nan \n


### Human: powerflex 753 and micrologix 1100 messaging Summary: will 500CPU write messages cause EEPROM damage I started messaging a 753 through a 22 com e from a micro 1100 using a 500CPU write message. After doing further research, reading the 22 com e manual, I see all examples show using the CIP Generic write, which writes to NVram, and CIP generic put which writes to rom. Wondering if my method will cause EEPROM damage over time. ### Assistant: The 22-COMM-E is not compatible with the PF753. You need a 20-COMM-E. \n


### Human: Kinetix 350 - 2097-V33-PR1-LM InPosition very slow Summary: Kinetix 350 - 2097-V33-PR1-LM InPosition very slow Kinetix 350 - 2097-V33-PR1-LM InPosition very slow: I am using 1769-L33ERM, linked to Kinetix 350. I have established the communication between the drive and the PLC. I am at the initial stage trying to test the Move commands to the drive. Used the MSO command to ON the servo. Then the MAM command to move the servo in Incremetal type. I am using the Rotary Transmission, High response, point to point type. I move it 360 deg for one full revolution. The speed is 4500 rpm, The acc is 5000 /sec2, The decc is 5000 /sec2. It takes nearly one sec to reach 358+ and another two secs to reach 360. I am not sure why it takes so long to reach the inPosition. Is there any othere important settings to be done. If manual tune can solve it, what are the parameters I need to change to make it InPosition faster. Thanks in advance for your help. ### Assistant: The model of Motor I am using is MPL-A1510V-Hxx2 \n

### Human: PF755 with Stegmann and BiSS encoders Summary: Dual feedback of different types with a PF755 UFB module. We have a PF755 on CIP application that requires a Stegmann SIN/COS encoder as the primary feedback and a BiSS linear encoder as the secondary feedback. Can this combination be configured into a single UFB module? If so, how would it be wired? I can't seem to find any diagrams that show dual feedback wiring for the UFB. ### Assistant: nan \n


### Human: Ultra3000 E20 fault I have three machines with an Ultra3000 drive using sercos interface. All three machines have very similar design and are less than 2 years old. Two of the three machines have E20 faults intermittently. The newest machine is the one that doesnt fault on E20. I have talked to AB and tried all the likely solutions (changed motor, cables, routing, grounding techniques) but nothing seems to help. We may get rid of it for a while, then it appears out of nowhere again. The two machines that are faulting out are fed from the same 575 V sub, but we do have isolation transformers. The machine that isn't faulting is fed from a different 480 V sub. Just wondering if it is a power/harmonics issue? Has anyone had this issue? ### Assistant: Just out of curiosity, have you matched the firmware of the newer Ultra 3000 to the older ones? \n

### Human: 755 Motion Feed Back fault Summary: Feedback Data Loss FL Fault Hi I have an application where I am using a 755 drive as a motion drive over ethernet controlled by a L73 cpu rev 20. I managed to commission before the hardware got delivered to site and all functioned well. At site I am getting a FeedbackDataLossFLFault and the 20-750-UFB-1 indicates that it has a fault by flashing red. According to the Fault this is what it describes: The number of consecutive missed or corrupted serial data packets over the serial data channel from a feedback device has exceeded the feedback data loss Factory Limit. The offending feedbackfchannel is encoded in the associated Faultt/Alarm Sub Code. I have checked the feedback cable, wiring to the drive and even swapped servo motors and new UFB, but mo luck.

### Human: SMC-3 delta Summary: 230v - 400v hi all, I have a motor: 22 kw - 230v. delta / 400v. star . Can I use a SMC-3 delta soft starter to run the motor with different voltage 230v and 400v, using contactors to make the delta or star configuration? and if I can do it, which is the better switch configuration to have a very soft start? thank you. ### Assistant: nan \n


### Human: NEW CIP Motion Operands- What do they do? Summary: Differences between Motion MCLM and MCCM commands in Sercos and CIP, or V17 and V21 if it's the version which caused changes. There are several new operands added onto the end of motion commands MCLM and MCCM (and maybe others) : Lock Position, Lock Direction, Event Distance and Calculated Data. In all of the examples I can find these values are zero for all of these commands. Lock Position and Lock Direction sound like the MCLM and MCCM command have a MAG like function. With Event Distance and Calculated Data, I don't even have a guess at what they are used for. In what set ups or situations are these operands used? ### Assistant: ET, I think it's worth contacting Tech Support to get answers for these questions. If you do, please publish what you get from them here. \n


### Human: PF755 in Torque Mode Unwind App Does anyone have experience with an ac drive running in torque mode? What will drive do when it is used in torque-mode running an unwind application? I have an application that is applying constant tension in forward mode but occasionally the product unwinds and the drive will be forced in reverse. The tension is operator's selectable and the drive is running in Min Speed/Torque SLAT-3. The maximum speed is clamped thru SLAT-3. What do I expect from the drive when I force it in reverse like un-winding applications? Although I am using PF755 Ethernet, the PF700 should behave the same. Any feedback will be appreciated. ### Assistant: Noor Shah, did you get any support from your local Rockwell distributor on this? \n


### Human: MATC vs MAPC Summary: What is the main difference?I have an applications where cutting blade has to match speed of a material for certain time, then let material move certain distance and cut again... I tried to use MATC and it works, the complexity is that if I change material cut distance (requirement), speed does not adjust, it just scales up or down. I am trying to figure out how MATC is used, can someone explain in simple words how this instruction works and how do you relate position to the master? Thanks! ### Assistant: Can we assume the master encoder runs on the material? I would think an MAPC (position cam) is a better choice. You would use MCCP in conjunction with MAPC in order to define the region at which the blade runs at web speed, and then can be faster as needed to recover. I wouldn't touch a time cam at all for the exact reason you've encountered. \n


### Human: MDAC or Other? Summary: Flying Knife Control I am working on a flying rotary knife control where we are removing a mechanical clutch and replacing it wil a servo drive. I am relatively green to using the more complex servo motions outside of MAM, MAS, MAJ ect. I've been reading through all of the different functions in the Motion Instructions manual and other manuals and the MDAC seems like what I need. Here's a breif summary of the application. A web of film is feed through a set of rollers and is actuated to run and feed out a specific length of film. As the film is being fed a cut position is calculated to actuate the knife servo. The knife servo needs to ramp up to match the surface speed of the film and make 1 revolution cutting the film and returning to the start positon. I currently have the master servo units setup as inches and the knife as revolutions. I have the unit working now using two MAM's and calculating the speed of the knife based on a snapshot of the feed speed when the knife is signaled to cut. It is working like this but is not optimal as the feed is decelerating and the knife is at a constant speed so there is a mismatch at the end of the cut because of this. Depending on cut length and feed speed the deceleration could occur at different points so I feel the two axis speeds need to be tied together somehow. I played around with the MDAC some but was unable to get it to work. The knife MAM would fault on a 95 which from what I could find is a error with the speed units not being set to Units per master which they are. I'm not having much luck getting this to work so I'm looking for some direction or insight as to the best way to accomplish this task. I am by no means stuck on using the MDAC and am open to any ideas or suggestions. ### Assistant: I think I've figured it out. After 2 hours of reading I found the necessary information on setting up the MDAC. What I had missed was setting up the Lock Position / Lock Direction in the MAM correctly. I set the Lock Direction as Position forward only and the Lock Position as the Calculated cut position based on the master position. The Speed units are all set to units per master unit and I calculated out the MAM speed based on Slave Rev / Master Inch. The MDAC also needs to be cycled off and on for every MAM cycle. Now I just need to work on tuning the spikes out. For Reference the majority of the usefull information I found was in Chapter 6 - MDSC Functionality of the Motion Instructions Reference Manual. \n

### Human: Circular Interpolation with L30ERM? Summary: Is it possible to create a circular motion with an L30ERM (or less?) CPU and a Kinetics? ### Assistant: Yes. There are some native instructions inside Logix5000 to do this. Take a look at the Motion Coordinated instructions: MCS MCLM MCCM MCCD MCSD etc. Look in the logix5000 help file for multi-axis coordinated motion instructions. \n


### Human: 9/440 Series Summary: Revision Number I need help. I have a module: CAT 8520-3APA1 SER. C PART 176406 REV 03 DATE 060299 damaged! I get a model CAT 8520-3APA1 SER. C PART 176406 REV 01 The only difference is the series 01 instead 03, can I use it without problem? ### Assistant: nan \n


### Human: 115V 3 - Phase; 400Hz Summary: Curious if someone has had success with this. I've been approached about using a VFD for a 115V 3 - phase, 400Hz application. This is being used for some sort of test equipment (clear description was not provided). I know that the drive will output the voltage from 0 - to rated, however, I'm more curious if anyone has done an application such as this, if they ran into any kind of peak voltage troubles (where the DC bus is can be around 180 - 280Vdc, depending on the AC in)? I believe conseptually this is possible, but I don't want to sell an incorrect solution to a customer. Thank you. ### Assistant: nan \n


### Human: Controlling a PowerFlex 755 with serial MODBUS over RS485? Summary: Controlling a PowerFlex 755 with serial MODBUS over RS485? Can I controll a PowerFlex 755 with serial MODBUS over RS485, using the built in DPI port? ### Assistant: You will most likely have to use the 20-COMM-M Modbus/TCP communication adapter option. http://literature.rockwellautomation.com/idc/groups/literature/documents/um/20comm-um014_-en-p.pdf \n


### Human: Upgrade 1336 Plus II to PowerFlex 70 Summary: Looking for information for converting prameters from 1336 Plus II to PFlex70 I am Upgrading a 1336 Plus II to PowerFlex 70. The 1336 Plus II uses the 1336-GM1 Remote IO adapter and the PowerFlex will be using the 20-COMM-R. I have the user manuals for both drives. Does anyone know of any information such as a cross reference for the Parameters. I thought I would ask before I spend a lot of time figuring it out for myself. Thanks for any help. ### Assistant: You might try the following link: http://www.ab.com/support/abdrives/conversion/index.html It looks like the one at the top is exactly what you're asking for. \n


### Human: Torque vs.speed curve on MPL servo motor Summary: Why I can't find the curve about torque and speed. Where I can find curve between torque vs. speed about MPL motor just for my selection based on caculated result data on mechanical part? ### Assistant: You can use Rockwell's free tool Motion Analyzer to do this: http://ab.rockwellautomation.com/Motion-Control/Motion-Analyzer-Software It's not a small download, but it IS a very good tool for sizing Rockwell servos. \n


### Human: PowerFlex 700 cannot rotate tune Summary: PowerFlex 700 cannot rotate tune Hi, I have three PowerFlex 700 Drives (20B-C-3P5-A-0-A-Y-N-A-N-C-0) that I am using to drive blowers with 2HP 380 VAC Vector Drive Motors. I am using these drives in FVC Vector Mode. According to the user manual, I believe that in FVC Vector Mode, I should be able to do a rotate tune (by setting parameter ### Assistant: Isn't there a parameter involved with autotunes for setting maximum permissable torque during the tuning process? If this is too low, then the drive would not reach its autotune speed and thus give you the fault you're encountering. This has been my experience with PF750s at least. You need to have that autotune torque value high enough. \n


### Human: Motion group overlap fault Summary: Which will cause the motion group overlap fault and Could you give the discription for that ### Assistant: Your coarse update time is set too short. https://rockwellautomation.custhelp.com/app/answers/detail/a_id/39085 https://rockwellautomation.custhelp.com/app/answers/detail/a_id/39084 Take a look at page 44 of motion-um003_-en-p \n


### Human: Kinetix 300 Vertical Brake Summary: Need information on wiring of control and timing for vertical application with holding brake We have a vertical application. The servo motor has a holding brake. An emergency turn off requires the following sequence (this is easy to achieve in other servos) 1. Press emergency stop 2. Signal (which one ?) to the Kinetix 300 is dropped (logic power and 3 phase is kept) 3. Kinetix brings any motion to a halt but holding torque is still on. 4. The Kinetix brake release output turns off to set the holding brake, holding power is maintained 5. A set time later (to allow the holding brake to fully engage) the holding power is released and the drive is disabled. External safety relay timed contacts will - after this action - remove power from the holding brake circuit and turn off the safety inputs to the Kinetix. (This wiring is already in place) We are confused as to the wiring/settings to achieve the numbered steps. This has been fairly easy and actually spelled out in manuals on other servo systems. ### Assistant: The place to start is here: http://literature.rockwellautomation.com/idc/groups/literature/documents/um/2097-um001_-en-p.pdf Page 93 shows the two parameters you would need to set (651 and 652) for time delays regarding the brake output of the K300 drive. You will need to coordinate the two parameters with your external safety relay timed contacts to make this work. It's not a control scheme I would be very happy with - the K300 is a very simplistic servo. I would take complete control of the brake via external logic (sounds like you already have it), and not do any brake control within the K300 at all. \n


### Human: Linx 3.0. comes with connected components workbench, does not work. HELP Summary: Linx 3.0 installed from CCW crashes when I open it or who active in RSL500 Hey all. I got a copy of the new Connected Components workbench from a contact at Graybar. I installed it and all associated files. Included in the install is Linx V.3.0. This is an upgrade from my current V2.59. After the install my CCW works just fine as well as RSL5000. However, when I open Linx and click on any processor to look at it crashes Linx and shuts down. As well when I go to who active on RSL500 and click on a processor the program crashes and shuts down. I got the advice from tech support to uninstall my CCW. After the un-install the issue remained. Only after un-installing Linx 3.0. and re-installing my previous 2.59 version is everthing back to rights. I am wondering if anybody else has had similar issues and can I install CCW and run it with Linx 2.59. I should mention I am using WIN7(64bit). Thanks ### Assistant: I've encountered a problem with Linx 3.x in that it didn't activate correctly (came through as lite when I had activation for OEM Toolkit). The fix was to upgrade FactoryTalk Activation Manager. \n


### Human: Motion Instructions I'm working on a project in which I trigger motion commands based on the encoder value of a master encoder. I've successfully done this using K6000 drives and ver 18 of RSL5k. I used a MAW to catch the encoder value and trigger motion. Now i'm using ver. 20 and K6500 drives. The new axis setup saves some math scaling encoder counts, etc, but now the MAW instruction doesn't catch the scaled value and trigger. Is there a way to access the raw encoder counts of a encoder (aux input) and use the scaled values? Or should I use something other than a MAW watch to trigger motion? Any help or direction is appreciated. ### Assistant: I'd been taught MAW is used when you don't know exactly when the trigger input will occur, such as a registration mark on a web used to make registration position corrections. Since you're basing your operation off the master encoder, and it comes in as a motion axis, the MAOC instruction might make much more sense. The output from this instruction can be set for whatever position you desire on the master encoder, and you can cause outputs for a number of positions. Another name for this function is Programmable Limit Switch (PLS in the vernacular). MAOC is nice because once you issue the command, you do not have to keep on re-arming it the way MAW must be. It's fire-and-forget. You can adjust the position that causes the output to fire without having to reissue the command as well. I've used both commands, both can be tricky and finicky. Are you sure your MAW arming logic is sound? I've run into problems with my initiating logic in the past trying to arm an MAW that was already armed. \n


### Human: IS there a way to remove the torque and redefine position without disabling the servo? This is what I need to do: I have a MAM. I make a move, when the move is complete I need to remove the torque redefine the position, reenable the torque and be prepared to make another move. Currently the previous programmer uses a Motion Axis Stop, redefines and Motion axis on. and it takes 3ms. Is there a better faster way that would take only 1ms? The toque can not be removed without disabling it. Is there a way to remove the torque and redifine position without disabling the servo? ### Assistant: I don't think disable the drive to issue MRP. Can you eliminate those steps and just issue MRP when the axis has stopped moving? However, MRP does take some time (more than just one scan). Having it work in 3ms in the current configuration is impressive all on its own. \n


### Human: Correct way to change a PF drive (ENET) Summary: I need to know which is the best way to make the new drive recognized by PLC when I replace a new one When I have a drive that need to be replace, what i usually did is either these 2 ways : 1. Put the new drive in, config the new IP add, reset the ENET switch (if needed some time) and let the PLC connect to this drive. After that i use RSLogix to access the parameter and config them as my perference 2. Copy the parameter from the existing drive to HIM, replace the drive and transfer it to the new drive. Reset the switch These ways always work for me until one day I can not make the PLC regconize the new drive (Yellow triangle mark) . On the drive, NET A & NET B lamp blinking . I can still ping the drive from the network and see it by RSLinx. After all the efforts (to reset PLC, reset switch, try another drive, redownload the PLC program), i come to the last way : delete the drive out of the IO configuration and add it in again - match drive - redownload the program. Then it work. Could anyone tell me what wrong i am doing to change the drive and what is the best way to do in this case. I really dont want to redownload the program because it make me lost some tag value . Thanks in advance ### Assistant: This sounds like a firmware mismatch. The plc program is looking for a specific firmware version but your new drive has something different. That you match the drive after deleting it pulls the correct firmware number in. You should flash the drive to the firmware version expected by the plc program to have a more seamless replacement. Alternatively you can disable hardware keying, but i think that will cause you different problems. \n


### Human: Powerflex 4 drive with 1203-USB issues. Summary: Cannot connect to drive! Hello everyone. So here is my problem. I have a Powerflex 4 drive that I am using to control a 3 phase motor. To start with, I will let everyone know what I have, and what I'm trying to do, then my problem. 1: Windows XP pro SP3 on a Dell Latitude D610 2: RSLinx Classic 2.59 3: 1203-USB Flashed with the 1.004 firmware 4: Connected Comnponents workbench 2.0 So here is what I've done already. I installed the connected components workbench 2.0 which gave me all of the above. Then I plugged the 1203 into my USB port, and installed the drivers that I downloaded from AB. After that, I setup the driver in RSLinx exactly to the instructions listed in the manual. When I go to RS Who, I get nothing for a drive. So I looked around and see there was a firmware update. So I updated to the 1.004 firmware using the hyperterminal method. That worked perfect. No errors. Tried again, and it still didn't work. I know I'm on Com 4, because when I go to control panel, it tells me so. I used hyper terminal to change the drive to a master instead of AUTO, and did a reset, and that didn't work. I have even went to the extreme of reinstalling windows, and trying different options in the OS... No firewall, etc... Nothing. IT did connect one time, and now I cannot figure out what it did to duplicate that. When I upgraded the firmware, I ran the controlflash install program which put a bunch of folders under 0001. Then in hyperterminal I selected 0001/0078/2500 and the boot one first, then the combo one second. I'm not sure what all the other folders are for. Is this correct? Any ideas? Thanks in advance Pat ### Assistant: If I understand correctly, you can communicate via Hyper terminal, but not RSLinx. Is the main diamond shaped light on the 1203-USB blinking green? Does the drive have any other comm modules (e.g. 22-comm-E)? Is it part of a Multi-Drive setup? What are the settings you used with RSLinx? (Please list all items, or provide a screen shot) Generally, it should be: - RS-232 DF1 Devices - Device: 1770-KF2/1785-KE/SCANport - Baud Rate: 115200 - Error Checking: CRC Other options: - Is Hyper terminal closed? (RSLinx must be able to access the comm port) - In the RSWho window, right click on the driver and get what the properties are. - Is RSLinx browsing? (animated icon on driver; “Autobrowse” checked) \n


### Human: Powerflex 755 bus voltage HIM display does not match measured voltage Summary: Drive has failed, but HIM is not helpful in diagnosing the problem Over the span of a day, A 480VAC PF755 drive configured for CIP motion initially was reporting DECEL INHIBIT faults. Then it began reporting BUS OVERVOLTAGE faults. The end user noted that the bus voltage shown on the drive HIM reported 680V dc bus voltage. At the time of measurement, the line-in voltage showed 470VAC. The end user measured 240-300V bus voltage. That surprised me so much, I had him measure a second drive in the system. It measured 680V (or close enough to the HIM display of that drive not to question it). Remeasuring the bus voltage on the suspect drive, the user got 300V bus voltage, with voltage fluctuations as low as 0V. Replacing the drive got the system operational again. My concern is that the process values on the HIM are worthless. The HIM reported 680V bus voltage the whole time the user measured much lower. Any suggested explanations for this? ### Assistant: most likely the voltage feedback board is faulty therefore the HIM cannot display the correct value. \n


### Human: Where can I FIND OUT axis tag stucture definition? Summary: Where can I FIND OUT axis tag stucture definition? Such as axis. actual position is very distinct. But I want know the others detailed meaning. ### Assistant: http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/motion-rm003_-en-p.pdf http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/motion-rm002_-en-p.pdf Both of these reference manuals are very good places to start. \n


### Human: What is the position frame of axes after homing? Summary: After homing sequence occurence,we will get our desired position frame of axes,so what about is that? in the homing tab,we appoint homing mode=active switch ,position=X,velocity =X,direction =bidirection........ In one word, home switch is our desired actual phisical position,but what is the reason for home position setting in the tab. After homing completing, now there will be a actual position figure from feedback encoder, if the difference between the value and home position parameter in tab, what the relationship of these two values? In motion control we should build up the coordinate system for the position.Would you please give the example to explain? Look forward to hear from you! ### Assistant: Anybody can give the answer for me? I appreciate your help! \n


### Human: downsides of running drive at low frequency for long periods? Summary: What are the disadvantages of running a VFD at a low frequency for an extended amount of time? ### Assistant: The VFD doesn't care what output frequency, it will run anywhere in it's range all day. The problem is the motor. A normal general purpose motor TEFC motor will not cool itself at low speed and burn up windings. \n


### Human: Homing sequence Summary: Some points during sequence in the diagram Home mode = active sequence = home to switch forward bidirectional 1.When started,Axis will forword toward home switch direction,clear the sensor and then decelerate. My question is what the sentence underlined in the picture means? ### Assistant: The language is butchered, and the reference point is wrong. What #2 SHOULD say is: 2. If the axis begins the homing sequence with the home limit switch already on (if the axis position is between point 1 and point 2), it will begin homing motion by moving in the reverse direction at the home return speed until the home limit switch clears, and then the axis stops. \n


### Human: Opto outputs on a Flex 40 drive to a PLC input. Can the opto outputs (17 or 18) be wired directly to a PLC input? Since the opto outputs are sinking signals, I assume the PLC input would have to be sourcing? Am I correct in this assumption? ### Assistant: Yes, your assumption is correct. Your PLC should be able to see 0 volt as a true signal. Anyway, there is a possibility to invert the logic signal, to use instead a sinking input, that is a more used module. If you are interested in it, please send me a Private Message here in the forum with your e-mail address and I will send you back some indications. Hope this helps… - fuzzy logic \n


### Human: Kinetix 6200 Driver Safety Fault FLT03 Summary: What is the means of FLT 03, without extend error code? How can we avoid this kind of issue? Does any detail information of this fault?

Does any detail information of this fault? What is the better solution to resolve this safety circuit fault? Thanks ### Assistant: This maybe caused by the connection condiction of the control module and the power module. \n


### Human: 1336 plus and 1336 Plus 2 serial fault Hi, I have got a couple of drives (1336 plus and 1336 Plus 2) I want to connect (via scanport - 1203-module) to a logix controller. However, some of them give F10-serial fault when the scanport cable is unplugged. This network is only for reading parameters (logging). I've changed parameter 92 (logic mask) so the scanport adapter (2) shouldn't be able to fault, but still it does. Any thoughts? Thanks ### Assistant: nan \n


### Human: PF750 Fibers Functions Summary: Looking for a white paper or write-up on the Fibers Functions in the PowerFlex 750 family I'm looking for something more descriptive than is in the 750-PM001 on the fibers functions. Anyone know of any manuals, write-ups, or have an example they would care to share on this? Thanks, Bryan ### Assistant: nan \n


### Human: Powerflex 4M Summary: Motor creeping at min frequency Hi, i have a 4M 22FD2P5N113 Drive controlled by a 4-20 mA signal. P104 is set at 0 Hz and P105 at 100 Hz, when the machine puts out 4mA or less when it has faulted 3.67 mA the motor is still creeping and not coming to a complete stop.What can i set to stop this. Thanks in advance Geoff ### Assistant: Geoff, this is a problem when you work with an analog speed signal rather than one that might come through a network connection. If one were sending the speed reference via Ethernet-IP, you can be sure that your zero speed truly is zero. The analog inputs can't give a true zero. To stop the motor, you'll need to use the digital start/stop inputs of the drive. \n


### Human: Following 842E-M Encoder with Kinetix 350 Summary: Question on setting up 842E-M as a Virtual Master I am using a 842E-M on a piece of equipment. I have a machine that follows this position. Best case scenario I would use the CIP Ethernet encoder, but there is about a four to six week lead time right now for those. I would just set that as the Master axis is my MAPC and go from there. So for now I am using a regular Absolute Ethernet Encoder. I recieve all my values with no issue. I am guessing I need to use a Virtual Master to imitate the encoder position. I am using the example from the TechNotes on how the setup a Virtual Master using two MAM's for a HSC card with an encoder. Should I do the same here? I am trying it, but the error on it is pretty large. I am open for all suggestions, because I have been beat down by this problem for a few days now. ### Assistant: Generally, one connects a master encoder through the auxiliary encoder input of a servo axis. At this point in time, it must be a SERVO axis; while PF755 drives support a number of simultaneous encoder inputs, none of them can be used as an auxiliary to be master. The K350 does not have an auxiliary encoder input, so you're stuck using the HSC card as you described. Can you give some more detail about the error? There should be no error on the virtual axis at all? Or do you mean the difference between your encoder input, and the virtual axis? Did you set the values identical to the example in the tech note? I see that (in the V16 example) the check box for master delay compensation is set. Getting the Ethernet/IP encoder is the best route for what you desire; either that or switch the K350 to a K6500; though I'm guessing that isn't going to fly because you probably used the K350 for reasons of cost. \n


### Human: Kinetix 6000 contactor enable keep dropping out Summary: Kinetix contactor enable on main drive turns on and off over 1000 time in a day. I am having an intermittent Kinetix 6000 drive fault. Contactor enable on first drive on the rack is dropping out. This cause main three phase contactor to drop. Monitored it overnight and it had over 1000 on and offs. Replaced the drive thinking that drive is bad, it still had same issue. Checked whole rack for spare cap issue. My next step is to replace back-plane. Do any body had same issue? ### Assistant: The signal controlling the enable comes from where? If this is controlled by software logic, might need to check that there's not something strange there. If the control for the enable is hardware based, you might check all of the terminals comprising the circuit. It sounds like a loose wire. \n


### Human: PF700S Torque mode Hi, When you used to control a winder using Min Spd/Torque mode P110. Which parameter is your torque reference and your min. speed reference? Can you share how you did it? Thank you, ### Assistant: The torque reference will be P427 (Torque Ref A Sel) or P431 (Torque Ref B Sel) and the [Minimum Speed] will be P038. Refer to : http://literature.rockwellautomation.com/idc/groups/literature/documents/um/20b-um002_-en-p.pdf Page 26. and http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/pflex-rm001_-en-e.pdf for detailed VFD operation. \n


### Human: SMC Dialog plus Summary: Updating firmware IS there a procedure for updating the firmware on a SMC Dialog plus drive? We have a couple of units that give a Line Fault 15, which can be masked out in a newer revision. Havee never tried to upadte firmware on a drive. Any help would be appreciated. ### Assistant: Flashing a drive (or SMC) usually means first downloading the desired firmware install package from Rockwell, running it so it installs (or updates) ControlFlash. You then need to connect to the drive in some manner. You've not stated anything about networks; you can connect to the drive via RSLinx using a 1203-USB adapter, Ethernet/IP, etc. Next, you'd actually RUN ControlFlash, selecting what type of device you're going to flash, pick the firmware version you wish to install, pick the actual device from Linx, and execute. The two hardest parts are getting good communications (making Linx work), and figuring out which type of device you're going to flash. The descriptions in ControlFlash sometimes are cryptic or do not match what you think the drive is. ControlFlash is used to flash ControlLogix and CompactLogix hardware as well. \n


### Human: Studio5000 and MPL motor with resolver Hi, I start to configure PLC for new project which required to use one servo (MPL -B320P-R). I'm using Studio5000 softwer to configure L18 controller with Kinetix 6500 modul. But there some fail was occured, because there is no option to choose this MPL motor with resolver (only H, M, S option are available). Is somebody knows what is going on, and how can I solve this problem. The stuff is ordered, so I don't want to change hardware configuration. Thank you in advance for any idea. Cheers ### Assistant: I found the same results through Studio 5000, but using Motion Analyser, tells me I can have a 2-pole Resolver. You'll need to place a call to tech support, I think. You could try updating the AOPs for Studio 5000, but I'm not sure there are any yet. \n


### Human: 400v Powerfelx 700A AC drives with 480V input and 460V motors Summary: Hi, We built a machine for 380V usage, now we have to use it in US with 480V. Hi All, We built a machine for 380V usage. Now we are forced to use it in states 480V. I know that there is a voltage setting in powerflex drives (High / Low Voltage). So My question is by selecting the high voltage option is it possible to use the same drive with 480V Input. If, Yes then I don't understand why there is a separate catalog numbers for 400 & 480V drive in powerflex. ### Assistant: Yes, there is a high/low voltage parameter permitting operation at 400V or 480V. There are different catalog numbers so that if you purchase a drive suitable for your geographical location, the drive defaults to the proper voltage. This makes it somewhat more attractive to purchase a Rockwell drive in Europe and other locations with 400V power without having to worry about getting that particular setting correct. If Rockwell defaulted to 480V power, they wouldn't sell as many outside the USA. \n


### Human: PF755 Summary: Drive Parameter Hi, Anyone knows what parameter to change in the drive when using a brake resistor? Any safety precaution about wiring will be much appreciated.

### Human: VFD Capacitor Life Summary: Curious about average capacitor life of a drive. Greetings all, I was asked by a customer today, what is the expected shelf life of a typical VFD capacitor. So, not knowing that answer, I turn to all you wonderful folks out here in the VFD world to draw on your experience. M customer's primary concern is how long they should feel comfortable with a spare drive on the shelf before worrying about the capacitor dielectric breaking down. I look forward to seeing all the responses. Thank you. ### Assistant: Hi I worked in a plant until the start of the year that was installed in around 1996 with hundreds 1336s, we had a few failures of drive capacitors in the first 3 to 5 years but after that I can not remember drive capacitors going, the controller cards are just starting to fail, spare drives in the store always worked. So from this I would say 10 to 15 years. Hope this helps Ian \n

### Human: PF753 - adjusting accel time Hello, I would like to increase the acceleration time on PF753 to see if this can minimize the overshooting when the machinery swtich over to other damper. The current setting on 753 is 1. Accel time 1 & 2 : 90 & 80 Hz 2. Decel time 1 & 2 : 90 & 80 Hz 3. Jog Acc Dec time : 80 Hz What are the differences between accel 1 & 2? Shoul I adjust varialbes for decel according to accel time? how about jog time? Currently, preset speed are assigned through 1~7 (12~10~20~22~40~50~60). what are these variables? is it something to do with accel time 1 and 2? The accel time switch over to other when it reaches the certain stage of preset speed? Thank you in advance, it will help me a lot ### Assistant: You should have a copy of the 750 programming manual: http://literature.rockwellautomation.com/idc/groups/literature/documents/pm/750-pm001_-en-p.pdf Page 107 gives definitions of parameters 535 through 538. Accel / Decel 1 & 2 are selected using either a digital input or a logic command from a network or devicelogix. Jog 1 and Jog 2 are chosen the same way. If you're not switching between accel / decel 1 & 2, then all you need to vary is Accel 1 and Decel 1. The preset speeds are also selected using digital inputs or logic commands via network. The accel and decel times are in seconds, not Hz. is 90 seconds ramp-up time normal for your application? May I suggest you upload the DNO file for this drive instead of the Excel file with just an image of it? Use the software you used to get the image (DriveExecutive) and upload it here. We'll be able to give you a better idea what's going on. \n


### Human: Can not found the papameter Tab in RSNetWorx for DeviceNet. I had try to configure the PF700S in the RSNetworx for DeviceNet. After I open the properties and try to modify the parameter. But it was missed of parameter Tab. All these step was do offline. Is there have any constrain on PF700S on DeviceNet Application? ### Assistant: I have the exact same problem, I've called Rockwell support and I have been told to:unregister the EDS for that drive (PF700S Phase II 480V 52A)RebootGet online with the network, the drive will appear as unknownRight click on the device and select Register Device (will execute the EDS Wizard)Create an EDS file following the steps suggested. Reboot againOpen RSNetworx and there should be the parameters tab. But also there is a but, the parameter tab I get is kind of corrupted or same of the options in some of the parameters are missing or not shown. So I'm calling Rockwell again to see what is going on. I'll will update this answer later. Sorry for my english. Regards, \n


### Human: 'position' and non position Summary: CIP Motion architecture What is the position and non-position in the IAB software? ### Assistant: There is no difference in part numbers between position and non-position drives. The difference matters to the communication module which will be talking to the drives. The 1756-EN2Xx Ethernet/IP cards can talk to up to 128 non-position drives, and up to 8 position drives (each position drive on the network decreases the number of non-position drives to which it can talk). http://literature.rockwellautomation.com/idc/groups/literature/documents/wp/motion-wp001_-en-p.pdf Look at page 48 of the PDF link above. EN3x Ethernet cards can talk to up to 128 drives of either type. Essentially, if you want position control and are using EN2Xx cards for communication, you can only have 8 per card. You can use the servos for velocity control and have many more. IAB is asking the question so it can help you figure out the network requirements. If you tell it you want 10 servo drives, all in position mode, it's going to come back and say you need 2x of 1756-EN2TR, or a single 1756-EN3TR. \n


### Human: PF755 Converter AC Single Phase Loss Fault Summary: What is this error and why does it only happen when the drive is under load? If i run the motor at 100% for 2-3 minutes, this fault occurs. Im assuming it has something to do with the loading. What do i need to look for? ### Assistant: You should have a copy of the programming manual handy: http://literature.rockwellautomation.com/idc/groups/literature/documents/pm/750-pm001_-en-p.pdf Go to page 305, error 17. The descriptions / actions for this fault are actually pretty straight forward. You say it happens only under load. What is the load/application? Does your load cause any sort of rapid, cyclic regeneration? The third bullet point would seem to be the correct solution for you, but you might want to look at the AC input as well. \n


### Human: Servo motor moves without any order Hi everybody! I introduce me, I'm Camilo from Argentina, and first of all, sorry my english, it's awful, I know! Ok, I'm working in a depalletizer of bottles, what uses 11 servo motors AB, with Kinetix 6000 controllers. The plc is a ControlLogix 5561. The problem is that, after do the homing of a particular servo, it moves without any order at a really high speed. There is no instruction in the program in that moment who ask the servo to move. Well, I changed the homing mode, originally it was in torque mode, and now is in torque-marker mode. After do this (about one month ago), the problem didn't reappear. But yesterday, unexpectedly appears again. It really makes me nuts! Somebody might know what is the problem? Thanks in advance! ### Assistant: Your English is better than many who use it as their first language. No worries. Homing to a torque level - do you have any sort of speed limit set? The motor is going to run at its full speed looking for a load so it can build up to the torque value you set. If your axis is always in torque mode, that may be what's happening. While there is no overt motion command (JOG, or MAM, for instance), if it's on and has a torque command, it will speed up looking for that torque. The fact that your homing mode change fixed the problem temporarily points to two things - either something changed in software timing, or something changed physically on your machine. Can you share the ACD file here so we can take a look? \n


### Human: Rotary camming Summary: need help with cam I am fairly new to motion programming and I am working on a rotary axis project. I need to match position of the gearbox output and I have the cam created to do this and it works fine. I need to advance and retartd the slave in relation to the master and this is where I have a problem. I am calculating the cam on the fly, the cam is calculating correctly but when the pend mapc locks and is running the cam, the slave will run to the unwind and stop and reverse. I have the mapc set to continuous. basicly I am shifting the slave up one segment. I also program this cam table into a mapc and it does the same. can I not offset the cam in a rotary application? any help is appreciated! ### Assistant: It sounds like you have two problems? First, the cam doesn't run continuous in one direction, but oscillates? And second, you cannot offset the cam? The answer to the second is yes, you can offset the cam. Issuing an incremental MAM on the slave axis will offset it. Post your ACD file, let us take a look at it. The answer to the first question could be difficult to to solve without seeing your cams. \n


### Human: Motion analyzer Summary: Why the drive which the software recommended is always the AM module?I think the first slot module sholud be IAM module. ### Assistant: The IAM power size is dependent on the number of drives and how they interact. If you have multiple drives, it is likely you want some of them to be operating at the same time. The default condition for multiple drives is to NOT have them running at the same time which minimizes the size of the IAM. Thus Motion Analyser first has you define all the axes, and if they work together or independently, and only then sizes / replaces the first AM with an IAM. It's not not intuitive, but it does make some sense. It would help if the sizing process were better described up front. \n


### Human: Axis_CIPDrive : what does Axis.StoppingStatus exactly mean? Summary: Axis_CIPDrive : what does Axis.StoppingStatus exactly mean? I'm wondering what the Axis.StoppingSTatus exactlymean? Does it mean that a 'MAS'-instruction is ongoing? I have regularly the error that a new motion instruction gets launched (f.ex. MAPC,...) when a MAS-stopinstruciton got launched just before. This errors the latest motion instruction with errorcode 78. This means a stopping action was ongoing (MAS) while executing a new motion-instruction. If possible i would like to add a condition before the latest motion instruction (MAPC) so that in case a MAS is ongoing, I do not relaunch it. Potentially a 'XIO Axis.StoppingStatus' could help except i don't find an exact description what this status means. REgards, FV ### Assistant: Take a look at Rockwell reference manual document: http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/motion-rm003_-en-p.pdf page 76. You are correct, this bit will be true while an MAS is in process, and you can use it in the manner you describe. \n


### Human: Drives Manufacturing Location Does anyone know where the PowerFlex drives are made from? If possible, are the PF4M, 4, 40 and 40P made from a different location? ### Assistant: I believe the PF70 and PF700 drives are still made in Mequon, Wisconsin. Not sure about PF4, PF40, or PF400. \n
