### Human: Powerflex70 0-10Vdc input funky I have a powerflex70 on a chiller controlling condenser fan motors. I measured the 10Vdc signal on my input terminal. But when I read what the VFD is reading with parameter 17, it's flickering between -5Vdc to 4Vdc. Installed new shielded wire between my controller output and the VFD but with the same results. See the video here: https://imgur.com/gallery/hT2VvS5 ### Assistant: Is the shield on your new cable grounded at the VFD end? Is this new cable run near AC cables (such as VFD line in or motor cables)? When you say you've measured the analog signal at your input terminals, could you be more specific? Are you saying you measured the signal at the VFD analog input terminals and the signal did not flicker on your multimeter? Using a multimeter to read the signal: have you lifted both conductors from the VFD terminals and measured it? What provides the analog input signal? A potentiometer? An analog output from a PLC? \n

### Human: Configuring PF755 IP through HIM, Checking, comparing New Firmware of Main Board with Drive... Dear Sir, One of my Power Flex Drive PF755 Main Board has failed while power was made ON after Shutdown.Indication on HIM were sufficient to understand this apart from the fact that none of the Keys on HIM were operative that time. I was having the Backup of the Drive which is used for Uncoiler applicatio. I am in need of small Manual/ Lesson for Configuring New IP using HIM after replacing Main Board in such a way that even after power recycle the Parametered IP of the Drive through HIM does not changes. Once the IP is configured , 1)How to check the Firmware of the Drive New Main Board and match it with the Firmware of my Old Main Board with respect to the available backup of the Drive. Once this is established Drive backup in my PC can be downloaded. Please send the available Lessons from your Data Bank of Problem solutions for Learning, adapting and solving similar problem that may come in future. ### Assistant: https://literature.rockwellautomation.com/idc/groups/literature/documents/pm/750-pm001_-en-p.pdf Refer to page 240 of the PDF above.

### Human: Powerflex 70 Drive Summary: Frequency SelectionPlease, how do I preset different frequency on the drive? I have the drive attached to a pump which required the pump to operate at different frequency due to the requirement of the downstream equipment. ### Assistant: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/20a-um001_-en-p.pdf You haven't given enough information about your system for us to give a definitive answer, but what you need is inside the manual PDF link above. \n


### Human: falha F110 mebrana do teclado Summary: boa tarde estou tendo problema com varios inversores PF525, apresentado esta falha como poderia soluciona-la? ### Assistant: In English: F110 means the drive detected a membrane keypad fault. This probably means one of the membrane keys is deformed such that it is permanently pressed. If the fault does not go away after cycling power, you will have to replace the control module. In Portuguese: F110 significa que o inversor detectou uma falha no teclado da membrana. Isso provavelmente significa que uma das teclas da membrana é deformada de tal forma que é permanentemente pressionada. Se a falha não desaparecer após a energização, você terá que substituir o módulo de controle. \n

### Human: Speed reference on 753 drive Summary: Too much speed on the motorHello everybody, My motor is running at the speed of 55Hz, but my reference speed is set at 50Hz, what could be the problem? Mokhoele Mahao ### Assistant: Mokhoele, it would take very little time to troubleshoot this if you would include the DNO file from DriveExecutive or whatever file format CCW uses for VFDs. You've given precisely zero useful information to help us help you. If you cannot get a DriveExecutive file or a CCW file for this VFD, you will have to tell us all about this application. How is the drive configured (flux vector, sensorless vector, V/Hz), what feedback, command speed source, and on and on. there are dozens of parameters affecting the operation of the VFD. You haven't even told us what the load is. Best chance for us to help you is to give us complete information about the application. \n


### Human: PowerFlex 525 Summary: PowerFlex 525 ,460, 3ph runs single phase without faulting out.I have a situation where a A/B PowerFlex 525 3ph,460vac ,15hp drive a motor with mechanical disc brake. The brake is fed separate from L1and L2 of PowerFlex , respective a contactor that turn on-off the brake, at some point fuse on L1 blown out , but the drive didn't fault but keep running with brake engaged (not released) My question is why the drive was still running single phase without any fault ? Was because feedback from L2 through brake coil to L1 to drive ? ### Assistant: Hi I do not have experience with PF 525 but do have it with PF 70-700, my recommendations for you are: Check if the phase lost detection is on or off, Read the Knowledgebase answer 578273 and Consider installing an external phase loss relay (this is what I have done) Bye \n


### Human: Setting parameter 445 on 753 Summary: Sensitive level in terms of %Good day, I wish to activate the phase loss on the 753 drive and I have a few questions 1. What is the correct setting of output phase loss level ( parameter 445) 2. The default setting is 200, and 200 is equal to what percentage of phase loss? 3. The sensitivity is based on voltage? M. Mahao ### Assistant: https://rockwellautomation.custhelp.com/app/answers/detail/a_id/719367/page/1 According to this knowledgebase article: F21 is Output Phase Loss, which means that the current in one or more phases has been lost or remains below the threshold set in Parameter 445 [Out PhaseLossLvl] for one second. Decreasing the threshold in Parameter 445 [Out PhaseLossLvl] will make the drive less sensitive to tripping. This is usually necessary when the motor is smaller than the drive rating. Check for an open output contactor or any loss of connection between the drive and motor. However, I'm pretty sure that the value in P445 is NOT in units of current; otherwise, why would the default value be 200? I don't think it's percentage either. However, no where I can I find a good definition or method to set this value properly. To activate output phase loss, you need to set parameter 444 to something that is useful to you (either alarm or fault). Default setting is ignore. You should be able to view the knowledgebase article; it is tagged as being for everyone. \n


### Human: Cyclone pump motor Summary: Change of speed, pressure and currentGood day, We have, 550V ac, 220KW motor pushing a cyclone pump. But after changing the propeller the motor misbehaved. At sometime the pressure and current drops and at same time speed slightly increases this happens in the intervals of say 20 minutes . We have checked the settings everything is still the same. Attached is the motor trends 1. Red line is the pressure 2. Blue line is the current 3. Green line in the motor speed M. Mahao ### Assistant: The motor pump is controlled by 755 M . Mahao \n

### Human: Powerflex 755 not reaching speed command We have a Powerflex 755 Drive that will not reach the commanded frequency setpoint. The Logic is telling the drive to run at 60Hz however the HIM is only reading about 6-8Hz. The motor barely, if at all spins at this Frequency and is a jumpy. Any ideas what might be causing this? ### Assistant: It would help if we knew how you had it setup. Direction Mode (Parameter 308) Speed Ref A Sel (Parameter 545) Anything else you can add that would help? \n


### Human: Power flex 527 ip address,Subnet mask & gate way getting default In power flex 527 the ip address and gateway are both same in our plant. (ex- IP address 192.168.2.84 ,subnet mask -255.255.255.0 & gateway 192.168.2.84 ). I set the ip address through dhcp . When after i connected to the network all the ipaddress,subnet mask & gateway getting defauls to 0.0.0.0. ### Assistant: If you are using DHCP (Dynamic Host Configuration Protocol) the settings of the powerflex will be issued from the DHCP server. you don't need to set the IP and subnet and gatweway manually. If you don't use DHCP your gateway adres cannot be the same as the IP adres of the device \n


### Human: Synchronization (motion) between three motors using 3 PowerFlex 525 VFDs and 3 encoders? Summary: 05BH00CB02AF encoders motion synchronizationI am trying to setup the motion tracking of a large platform using three motors controlled by three VFDs. These motors have to move at the same pace and be 100% synchronized otherwise the platform will break or the motors will get damaged. The drives are PowerFlex 525 with one encoder on each motor communicating with the encoder on the VFD. The encoder is 05BH00CB02AF. I am wondering what is the best way to sync the motion of these motors? and how to have safety check in place to stop the motion if one motor goes out of sync? I haven't seen the parameters from the encoders yet, but just wanted to check if Rockwell provides any modules that can handle motion synchronization? ### Assistant: You can't do this with 525 VFDs by themselves, but you could with 755s and some encoder splitters. In this scenario, one of the 3 motors would be the master and you would give speed commands to it. The other two motors will be slaves. The slaves will need two encoder cards (one for its encoder, one for the encoder signal coming from the master. The master encoder signal needs to go to the master drive and the two slaves, so you will need two encoder splitters to get three separate signal paths. Alternatively, you could use the PF755s and a single encoder card each, and also a CompactLogix processor capable of motion control - a 1769L30ERM or a 5069-L310ERM for instance. This eliminates the need for the encoder splitters and gives a lot more capability to the system, but at higher cost. I'm very partial to the compactlogix motion control approach. Going cheap on the application you describe will cost you in the end. 525 drives are not up to the task. \n


### Human: Power Flex 755 encoder card Summary: What might be reasons that causes encoder card failure in powerflex 755 drives. ### Assistant: We've encountered a number of ENC1 incremental encoder input card failures for PF750 drives (one customer's drive has eaten 3 of them, I think). We never found a convincing reason. Sorry, no solution, but you're not alone either. How many cards failed so far? \n


### Human: Save/Record Fault Code of PowerFlex 700s By Ethernet/DeviceNet or ControlNet, is there any solution to record the fault code in RSLogix 5000? thanks lots ### Assistant: I'm looking at old code we used on a standard system. We used Ethernet and issued a MSG command after the Drive:I.Faulted bit goes true. The MSG command was CIP Generic, service type Get Attribute Single, Service Code e, Class 97, Instance 1, Attribute 0. Destination is a UDT; construction shown here: \n


### Human: 753 Drive trips on 5028 SI Comm fault when stopping Summary: Powerflex 753 trips a 5028 SI comm fault, when drive is stopped, have DB brakesDrive setup-Powerflex 753 with Ethernet card, communicating with a Micrologix1400, running through drive wizard startup, and at the point where you check the direction of rotation, drive starts runs at entered speed, and when you hit stop icon on wizard, the drive trips a SI comm fault 5028, had wizard set for rapid stop and coast to stop, same results, have 4 drives in this setup and tried another drive and it also did same thing. any ideas? ### Assistant: George, have you seen this? https://rockwellautomation.custhelp.com/app/answers/detail/a_id/580277/page/1 \n


### Human: Getting Fault code 9 followed by Fault code 5 Summary: Can a blip current spike cause a drive to get Over Volt fault ?We have 150 HP motor that keeps getting a fault code 9 (Transistor Over temp) then followed up with a fault code 5 ( Over Volt). We put a Fluke metering on the drive while it was running and took samples of Current , Voltage on each phases. We saw we would get a blip of a current spike then the drive would follow up with a voltage spike and fault with a fault code 5. This would happen when the drive was running but not under load (cant bottom profiler knives not processing product at the time) and moving into position for the next cant set. So we are trying to figure out if we have a drive going bad or a motor torque issue. By the way when it faults it's set fault to coast and free spins for about 7 minutes. Any thoughts Drive or motor..... ### Assistant: What drive is this? How is the drive configured? Vector with feedback? Do you have a dynamic braking resistor? What speeds does the code 9 fault happen? \n


### Human: Powerflex 525 VFD Summary: Powerflex 525: Not showing ADC optionI have 10 powerflex 525 module in my program and all of them have ADC option except for one VFD. I compared all setting with the one which has this option and everything looks same, Anyone can tell me what am I doing wrong here? ### Assistant: In the image you shared, we can see two different drive tabs. The one labeled VFD80205 shows firmware 5.002. The one labeled VFD80305 shows firmware version 5.001. Since you can't see the ADC branch for that drive, the first thing I'd try is flashing VFD80305 up to firmware 5.002 to see if that fixes the problem. \n


### Human: Drive Program Does anyone know if I can transfer the program settings from a PowerFlex 700 to a 753 so that i don't have to completely redo the setup. I'm not sure if the setups are the same and when the replacement comes in production is going to want it ASAP. Any help would be greatly appreciated. ### Assistant: Refer to 20him-um001 document if you want to copy data from a PF700 to 753. Read page 50, Using the CopyCat Function. All you do, just upload data to PF700's HIM and use the PF700's HIM to download data to PF753. \n


### Human: Electronic Gear with PowerFlex 753 Hi, I have an Electronic Gearing Application in which a motor has to follow a segmented conveyor. The conveyor will have an incremental encoder coupled to it and so will the motor. I have done Electronic Gearing before utilizing a PowerFlex 700S and an induction motor. For that case I only needed to vary the Ratio which I did with a PanelView connected via DNet. In this case the Ratio will be fixed but once the motor and the conveyor be geared I will have to put the motor in phase with the conveyor which I would like to do by means of two buttons (advance - retard) I still haven't put much thinking on this. I would like to know if this can be done with a PF 753. I would like a simple application without using PF 755, PLC, PanelView. Thank you ### Assistant: It's doable. There are several knowledgebase articles which discuss what you're trying to do. https://rockwellautomation.custhelp.com/app/answers/detail/a_id/69877/page/1 https://rockwellautomation.custhelp.com/app/answers/detail/a_id/69750/page/1 \n


### Human: Power Flex 525 trips on F072 Summary: Power Flex 525 trips on F072I have around 11 nos of PF525 connected to the control logix system with L71 ( version 20) and 1756-en2tr ( supervisor enabled ) and a remote rack with 1756-en2tr ( supervisor not enabled) . The drives are connected in DLR . Under normal situations the system is fine , but once drives start one by one , a random drive trips on F072 , once i reset the drive it again works Ok for some time , but after some time any other random drive trips on F072. However if i make the network linear then the drives are running fine and there is no trip at all . but once i make network in ring the issues start appearing . I also replaced one of ethernet cable ( the one , when i removed the network becomes stable in linear ) with rockwell ethernet cable but still issues remain same. The drives do have ferrite core at the input and output Any suggestion to remove this unwanted noise ?? ### Assistant: The drive is reporting fault F072 on its display. Does your control network monitor network status for each Ethernet device? Is the Logix processor seeing the same dropout for whatever drive drops out? How long is each Ethernet cable connecting each node of the ring? Things to try: Change the ring supervisor over to the remote rack's EN2TR. Disable the supervisor in the primary rack. Change out the primary rack EN2TR. What would be wrong with leaving the network as linear? \n

### Human: Commutation lost cip motion with drive 755 Summary: After a power shut down or network lost, the cip motion goes to fault . I need to do a commutation to fix itGood morning I face to an issue on a conveyor driven in cip motion as Speedregulation. In fact, i have 4 consecutives conveyors with Same Brussless, same Drive. After a power shut down, one of the Conveyor is running in opposite direction shot time and goes to fault. We compare the prameter with other CIP motion, but all setting are similar. We switch the motor between conveyor, same issue. We swith drive between conveyor, same issue. we run out of idea about what to do. We found a rockwell blocs MRHD that can do the commutation by program. but it is a weird situation. And we still don't know how to collect the information commutation lost. Is someone have an idea for it? ### Assistant: You cannot change motor forward direction by setting it via DriveExecutive, CCW, or the HIM keypad. You must set forward direction using the hookup tests within the axis properties in Logix. Logix overwrites the entire drive parameter set with its own values. \n


### Human: MAS that does not work anymore Summary: MAS that does not work anymoreHello, I have 2 machines the same, 1 l306erm automaton in each machine and 2 kinetix 5500 drives in each I develop the program on the first machine, no worries. I import the same program on the second machine it works no worries, Except ... if I turn off the machine. when I restart, the shutdown commands MAS of the 2 dimmers work more. everything else works fine. MSO MAM .. etc .. only MAS stop engine orders that no longer work. If I get the program back into the machine and put it back into the (same) machine, it works again until the machine is turned off. Thanks for your help excuse my english this is an automatic translation. Bonjour, J'ai 2 machines les même, 1 automate l306erm dans chaque machine et 2 variateurs kinetix 5500 dans chaque j'ai développer le programme sur la première machine, pas de soucis. j'importe le même programme sur la deuxième machine cela fonctionne pas de soucis, Sauf ...si j'eteint la machine. lorsque je redémarre , les ordres d’arrêt MAS des 2 variateurs de fonctionne plus. tout le reste fonctionne correctement.

### Human: Powerflex 755 loses Motion parameters Summary: PF-755 loses motion parameters during communication faultWe have a Powerflex 755 with Motion control , connected to clx to en2tr having L85 as processor Software is studio 5000 with version 32 Normally we have the drive working fine with motion control , however some times when there is communication failure , the drives motion parameters get lost and we need to reprogram it again . I tried checking for ADC but cant see in the drive properties where the ADC option is present , i guess for 755 with CIP motion , the ADC configuration is not present . Any suggestions on this ### Assistant: When using a PF755 in CIP motion, ALL parameters come from the processor. You cannot program the drive directly (such as with CCW or DriveExecutive). Are you saying the PLC is losing the parameters defined in the axis properties page of the ControlLogix triee? You do not need ADC for such an application; in fact it can be a real hassle sometimes. When a Logix processor connects to a PF755 in a CIP motion environment, it downloads ALL parameters necessary. If you are setting parameters in the drive, then starting the processor, all the work you did setting the parameters gets wiped out by the PLC. This is a feature of Logix, not a bug. In this way, all programming happens within the logix environment. Call it one-stop programming. You do not have to set up logix programming, then motion programming in a different environment, then drive parameters in a third environment. \n


### Human: PF-753 Motor High current Summary: Motor takes high current during No load startupWe have PF-753 connected to 1.5Kw motor (for conveyor ) use . during some time startup on no load the current goes above 8A and the drive trips on overcurrnet. However under normal circumstances current starts at 7 and drops to 3 A which is normal . I checked the motor parameters entered and they are OK . The Accel time was 1 sec which we changed to 3 sec , but still same result The VFD is controlled through Ethernet . Any ideas ### Assistant: Hello again Raulvaze. What mode is the 753 operating? V/Hz, Sensorless Vector, Vector Open Feedback, or full Vector mode with feedback? Had this drive been previously configured for a different motor? We've encountered some instances where, even though you've gone through an autotune, not all parameters were set for the new motor. The fix for that situation is to perform a drive reset-to-defaults using the HIM; do not use CCW software reset-to-defaults (we know for a fact this does not work). Then go through a drive autotune. Resetting the drive back to factory defaults and re-autotuning may sound like a hassle, but it has fixed problems such as you have described numerous times for us. \n


### Human: FactoryTalk Network Manager Hi Guys, who knows about the new Software FactoryTalk Network Manager? I am trying to get the connection with a stratix 5700 but no success. I think i do not know how to really configure the network Manager so that it sees the switch. Now just for the test i have a LAN cable from switch (any port) to the host PC where Network Manager is installed; the IP of the PC is in the same range like the switch. i can not find where to add a new topic/post, that is why i posted this in here, sorry. Any ideas? thank you ### Assistant: Yes, the .alarm and .faulted bits come from the PF40. You are correct; from this logic, ANY alarm or ANY fault will turn on bit 31. The PF40 does not offer a lot of diagnostics. The parameter list offers parameters 7, 8, and 9 as Fault Code 1, 2 and 3, the three most recent faults. You could use MSG instructions to get the code stored in those three parameters. You would then need to create a look-up table based on data you can find here: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/22b-um001_-en-e.pdf Refer to section 4-3, page 95 of the PDF above. There's nothing wrong with the code. The drive is a simple drive. If you want a lot of useful diagnostics, a PF750 will give much more (at higher cost). This code tells you the drive faulted. You'd have to go to the drive, look at the fault code displayed on the LED display, and then look it up in the user manual. \n


### Human: Powerflex 525 Summary: My drive is putting out 24v on my safe inputsMy drive is putting out 24v on my safe inputs, I'm trying to input the 24v from a relay. Is there a parameter that I can change in the drive that will stop the drive from outputting and take an input? ### Assistant: Page 239 of the user manual: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/520-um001_-en-e.pdf Shows removal of the factory-installed jumper on the safety terminals in order to use Safe Torque Off. Did you remove the jumper? With the jumper installed, you would see voltage on the S1 and S2 terminals when measured to DC Common. Otherwise, there is no way for the S1 and S2 terminals to be sourcing voltage. They are only input terminals. \n


### Human: Multiple Drives Similar Failure- Grenading resistors. Summary: All 3 have blown the same resistor.In the last two weeks we've had 3 drives literally explode the R14 resistor on the main board of the drive. All three drives are catalog no 20G11G D 014 AA0NNNNN Frame 1 Series A 755 I doubt the problem is dirt, because we have the same model drive in dirtier areas that have been running for several years. If someone could point me in the right direction to find a solution to the probelm or explain what the resistor does, it will help me diagnose the problem. ### Assistant: What has changed in / around the application where these drives reside? The image you've shared is of a drive manufactured in November 2011. These are not new drives. If they've been running for years, and then suddenly failed, what changed in the area? Did something change in the utility power? Recent maintenance on the motors? New installation of equipment on the same utility feed? Something is different than the way things were three weeks ago. \n


### Human: PowerFlex 755 Dual Encoder AqB Feedback. Summary: PowerFlex 755 CIP Motion With Dual Encoder AqB Feedback. Manuals are contradicting themselves.Hello all, Can you have a Universal Feedback Card in a PowerFlex 755 Drive and use Dual AqB Feedback on Both Channels with two A B Z encoders? I'm working on a project which involves dual encoder feedback and CIP motion (I've listed the hardware and software which I'm using at the bottom of the post). I've found that there is some contradictory information in the PowerFlex 750-Series AC Drives Programming Manual (750-pm001) and the PowerFlex 750-Series AC Drives Technical Data (750-td001). The PowerFlex 750-Series AC Drives Programming Manual Appendix F (Page 522) shows that in Table 30 Universal Feedback Type and Connections that Digital AqB can be used. The wiring for the terminals are shown in the table. The PowerFlex 750-Series AC Drives Technical Data Encoder Combinations Compatible with Universal Feedback Boards(Page 153) shows that two incremental A B Z encoders can't be used. I've attached Images of both tables to this post. (One is the image attached to the post, the other is the file. There seems no way for linking multiple images). Can anyone provide some more detail on AqB? Which encoders use this feedback type other than A B Z? Hardware: Guard Logix 5580 Controller (1756-L82ES).

### Human: 1339 PLUSII Summary: Erratic frequency response on start-up accel rampWe're having a problem with an older drive starting a pump in auto when commanded to do so from the plc. On start-up it will trip and give us an alarm code 06 Motor Stall Fault. The description for the fault states that the current stayed above the [Current Limit} setting for more than 4 seconds. So I did some investigating with a 1730 Fluke Energy Logger because it can measure all three phases for volts, amps, hertz, KKw Kvar, etc... I also did some digging around through the settings. The Accel time was set for 17 seconds. The Motor NP fla is 285 Motor np volts is 460 RPM 1785 HP 250 I recorded the motor running from start up for 22 hours and the results surprised me. During the start-up acceleration to speed the frequency was very jumpy. There is a huge spike in frequency when the motor starts and it doesn't settle down until well after the accel time is over. Every time the frequency adjusts there are several spikes in the direction of the change. and the average volts/hertz ratio is 8.1343 (average of 6 measurements taken during acceleration). So my question is which is the most likely culprit, the main control board, the gate driver board, or the isolation board? Which should I check second? Which should I check last? Regards ### Assistant: Can you use DriveExecutive to trend commanded speed speed and feedback speed (if available)? Comparing the drive's commanded speed to the chart you have now from the fluke meter would provide some insight. Your chart makes it look like your set speed is 55Hz. The 17 second ramp gets you to 52.75hz, and then the drive takes another two minutes to get to 55 hz. The spikes you refer to are about .75hz in amplitude, and it looks like they last for about 5-10 seconds each. Can you describe the load this motor turns? Is it high inertia? How does the drive control the motor: V/hz, sensorless vector, closed loop vector? \n

### Human: DriveExecutive, PowerFlex 753 and 20-750-DENC-1 Summary: Can't configure a PF 753 with a DENC card in DriveExecutive 5.02Hi, I'm trying to create a Powerflex 753 with a Dual Encoder board 20-750-DENC-1 using DriveExecutive 5.02 but DriveExecutive doesn't allows me. I created one using CCW software V 11.00 from a friend's computer My question: Is there any version of DriveExecutive that allows me to create a PF753 with a DENC? it's just that CCW and I don't get along well together Thank you ### Assistant: I think your problem is the DriveExecutive version. You should upgrade to 5.06.03 (the last supported version of DriveExecutive). In addition, there may be some drives database file upgrades necessary to make this work. Go to Rockwell's PCDC site, pick the downloads section, type in DRIVES in the search box. The first one that comes back is drives database files for CCW. The second one is drives database files for DriveTools (DriveExecutive). \n

### Human: Drive Executive and 1395 Drives I have Drive Executive 4.05 and I am trying to connect to a 1395 drive but I can't get any response from the A/B adapter box connected between my laptop serial port and drive. How do I configure the software to detect the adapter box and talk to the 1395 drive. I had a technician in who was using an old version of drive explorer and he could get that to work. I could use some help from anyone who has had success with drive executive and 1395 drives. Someone told me that RSlinx should not be running but when I start drive executive it starts up rslinx. ### Assistant: hi.at first you need to configure driver for your serial port in rslinx.configure the driver as rs232 df1 devices and select the device as scanport.then try to connect your pc to 1395 drive using drive executive.hope this helps. \n


### Human: PowerFlex 40-E AC Drive via 22 COMM-E Summary: Fault F081Hello Guys, i have an issue with my powerFlex40; it's getting the F081 sometimes after a start. I have 4 pf40 and they are almost configured the same way and this working like this for years. the 4 pf are wired in the same way that when an emergency stop is pushed they are all powered off(400V); after acknowledging the e-stop they all start normally but that one brings sometimes(not always) the F081: Comm Loss. I can even not reproduce the issue because it is not happening every time. Any Ideas what it could be? the network cable of the pf goes to a switch (all the 4 pf are connected on that switch) and from the switch to a 1794-AENT Ethernet adapter. ### Assistant: What sort of logic processor controls the VFDs? \n


### Human: Using a 842-CM-MIP3BA Encoder to perform a follow Summary: Sample code req to create follow with encoder.Hello All Hopefully somebody out there has already performed this and may have some sample code. I am using a 842E-CM-MIP3BA Encoder to Follow a press. The encoder drives a motor that is installed in an off line m/c(( the motor is controlled from a 2198-H040ERS2 Drive)& the motion is controlled from a 1769-L18ERM-BB1B CONTROLLER)). I have Studio 5000 ver32.(I,m new to this so still learning) All I simply want to do is drive the motor from the encoder and if required change the motor direction and follow ratio. Any help would be appreciated guys. ### Assistant: Congratulations - you correctly selected a CIP motion Ethernet/IP encoder. It's very easy to NOT get it and you would not be able to take advantage of it in CIP motion. The encoder will be a CIP motion axis and you can issue a few commands to it, such as MAH and MRP. MAH only works if the homing tab of the axis is configured to be immediate. The axis can then be used as a master axis for camming or electronic gearing. In your case, it looks like MAG (motion axis gear) would work well. While it's a somewhat simple application, CIP motion is not all that simple. There's a lot to motion, more than can really be answered in a few forum posts. If you have a good local Rockwell representative or good Rockwell distributor, they should be able to spend an hour to help get you started. \n


### Human: PF 753 safety torque card fault Summary: Drive faults on safety toque faultWhen safety of the drive is triggered, the drive goes into safety torque fault and cannot be resetted remotely, the fault can only be cleared either clearing the fault on the drive or reset the drive, When changed the safety torque card, the problem does not occur for a few time when safety is triggered, is there any permenant solution other just replacing the card all the time? ### Assistant: What exactly is your STO fault? What exactly is the safety board you are using? How are you trying to reset the drive fault remotely? Via discrete inputs, or over network connection? How is the safe torque card wired (what opens the safe torque circuits)? The cards work well, if you wire them correctly and use them correctly. Look at page 20 of the link below: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/750-um002_-en-p.pdf Rockwell did a poor job labeling the two pairs of terminals. SP+ / SP- are labeled safety power, and SE+ / SE- are labeled safety enable. However, page 25 shows a typical wiring installation, where the two pairs are used as a dual channel control signal. To me, this is not very intuitive, but you can learn from the diagram on page 25. BOTH channels must be enabled / disabled at the same time. If you open only one, you will get a safe torque fault. Opening both simultaneously does not generate a safe torque FAULT; it simply shuts down the power stage. Closing them simultaneously allows the power stage to be used again without needed a fault reset; the drive is simply ready again. Look at page 332 of the programming manual at the link below: https://literature.rockwellautomation.com/idc/groups/literature/documents/pm/750-pm001_-en-p.pdf Are you getting fault 211? Is there a problem with the voltage you are feeding the safe torque board? \n


### Human: powerflex 40 firmware questions I have a powerflex 40 drive, 22B-D010N104BD. It has a non standard firmware and the OEM is no longer selling this drive. Is there anyway to get and flash the firmware to another drive of the same model? ### Assistant: I did not know custom firmware was an option, but your post made me look in the knowledgebase. I found the article pasted at the bottom of my post. Please note the spelling errors are Rockwell's. That said, do you HAVE to have the custom firmware? If the OEM is leaving you high and dry, what is the custom firmware give you? PowerFlex AC Drives with Custom, Specialty, or Proprietary Firmware 640821 | Date Created: 01/26/2015 | Last Updated: 01/12/2018 Access Level: Everyone Email this page Print Subscribe to Updates Question How do I know if my drive has custom, specialty or proprietary firmware? Answer The last two digits in the catalog stirng will give more infomation about these drives 22B-D010N104xx. A customer with a drive with custom, specialtiy or proprietary firmware can obtain the firmware or cassetee only through an authorized distributor. When flashing firmware or replacing the control cassette you have to the order the cassete with with the proper firmware. Standard firmware versions may not have the proper header files to allow it to be flashed to a custom firmware. \n


### Human: Pf40 port and mod cycling red When powering up drive. There is no comms enabled. The comms is via devicenet. Replaced comms card and drive but problem is still there, Any ideas on the solution for this ? ### Assistant: You'll need to connect to the drive using Connected Components Workbench or DriveExecutive to get more information. https://literature.rockwellautomation.com/idc/groups/literature/documents/um/22comm-um003_-en-p.pdf According to the 22-COMM-D manual, page 8-2 (96 of the PDF) a flashing red PORT light means: The adapter is not receiving communication from the drive, connected drive is faulted, or a drive is missing in Multi-Drive mode. Fixes for this include: Clear any drive faults. Verify that cables are securely connected. Cycle power to the drive. On the next page, a flashing red MOD light means: The adapter has failed the firmware test, connected drive is faulted, or a drive is missing in Multi-Drive mode. Fixes for this include: Clear faults in the drive. Cycle power to the drive. If cycling power does not correct the problem, the parameter settings may have been corrupted. Reset defaults and reconfigure the module. If resetting defaults does not correct the problem, flash the adapter with the latest firmware release. For Multi-Drive mode, determine which drive is missing or faulted. Check cabling and configuration settings (see Configuring the RS-485 Network section in Chapter 7). Since both lights flashing would seem to indicate a multi-drive mode, does this point you in the right direction? Is this a multidrive application? \n


### Human: 1768-L43 to PF753 via 20-750-enetr Summary: Port 6 DPI loss? move module to port 5 as solutionExisting EIP adaptor in port 6. While PLC in remote run is it possible to move EIP adaptor to port 5 without download. Keypad of vfd has option to fix after module moved to port 5 but if I proceed would a download of processor be required for PLC to work with EIP adaptor in port 5? ### Assistant: Yes, you would have to adjust the IO tree entry in the Logix PLC program in order to execute this change. Are you using Device Level Ring (DLR)? Are there other devices on the network? \n


### Human: Line reactors Summary: Motor sizeGood day, 1. What size of the motor do a connect reactors on the input and out of VSD? 2. The line reactors have two ratings e.g A1 & A2 = 80A and B1 & B2; Ith = 120A and what this means? M. Mahao ### Assistant: Hi, if I get your question right, the side depends on your particular installation or application. Basically you utilize a reactor connected to the input of your VFD to help to protect your VFD against disturbances of your power line and also to reduce the total harmonic distortion in the line introduced by the VFD. Basically you utilize a reactor between the VFD output and the motor to protect your VFD against reflected waves in installations where the motor and the VFD are “far” from each other and also to protect some motors from non-sinusoidal wave forms. There can be some other reasons why you want to use a reactor. If you utilize an input reactor connect A1, B1 and C1 to the line and A2, B2 and C2 to the VFD input terminals. If you utilize an output reactor, connect A1, B1 and C1 to the VFD output terminals and A2, B2, C2 to the motor In your case 80A is the rated fundamental amps and Ith = 120A is the max amps Hope this helps Bye \n


### Human: Not Enabled alarm Summary: What cause the alarmWe have not- enabled alarm on 753 drive what could have caused that? the drive cant start/run because of that alarm ### Assistant: Look at parameter 933 - Start Inhibits, to figure out what is preventing you from running. https://literature.rockwellautomation.com/idc/groups/literature/documents/pm/750-pm001_-en-p.pdf Page 162. \n

### Human: VFD Ring Network Issue Summary: Issue with Ring network causing issues when servicing equipment.I have ring network setup with one compact logix PLC and several VFDs, say 30 or so. There are times when one VFD needs to have it's disconnect turned off for service. This shuts down all the equipment on the ring. Because they are on one ring but on different conveyors I need to be able to remove a drive from service without taking the entire system down. Is there anything that can be done to prevent the system from shutting down when one drive is turned off? ### Assistant: What PLC model specifically? What firmware version is the PLC? What device is the ring master? A complete diagram of the ring would help us help you. Are you sure you have the ring configured properly? Are there any devices which are not rated for being in the ring? For instance, Wago Ethernet adapters with 2 ports can technically be in a ring, but are not rated for DLR service and could cause ring problems. \n


### Human: Kinetix 6000 E19 Summary: 2094-BM01-S showing E19we have replaced 2094-BM01-S with new same module. old was working fine but when we install new module, shows error E19 when RUN. Do we need to make some changes in configuration? or it should be plug and play? ### Assistant: E19 is position error fault. It's likely you have not hooked up the encoder cable or the power cable correctly. Go through the terminations on the drive very carefully. \n


### Human: Which motion instructions to use? Hi I have two servo axes (2 conveyors one after the other), master and slave in a linear movement. The slave must follow the master, but at a precise moment it stops to load products, after this it restarts and must catch up with a higher speed the position it should have if it had not had stop (like catching the lost train). The slave continuously repeats this movement and the master never stops and can have variable speed. Which motion instructions to use? ### Assistant: You're asking for a simple answer to a complex scenario. You might use MAG with some MAMs. You might use an MAPC if the stop point is consistent and repeatable. The truth of the matter is, you probably need a systems integrator to develop your application. \n


### Human: cannot get a Powerflex 755 drive to change direction Summary: i cannot get the Power flex drive to switch directions? FRW REV the key pad constantly shows rev ### Assistant: Bruce, if there's any chance you can upload a DNO file from DriveExecutive or whatever file format is used for Connected Components Workbench, that's the easiest, fastest way we could help you. There are several reasons why you might not be able to control direction from the HIM keypad. The drive could be configured for direction control via Ethernet or digital inputs from a PLC. The keypad could be masked from logical control. We'd be guessing at how you have the drive configured and take hours or days for back and forth communications. With the parameter file, any experts here would get you an answer in minutes. You can start looking at parameter 162 - DI Fwd / Reverse, and also at parameters 324, 325, 326 (various masks). If you do not have 750-PM001, get it here: https://literature.rockwellautomation.com/idc/groups/literature/documents/pm/750-pm001_-en-p.pdf You really cannot be in full control of a PF750 drive without this manual. Get us the parameter file one way or another and we'll get you a good answer. \n


### Human: Powerflex 525 Summary: Not receiving Drive Ready StatusWhen I reset my e-stop signal going to drive, I'm getting 'network ok' signal from the VFD but not the drive ready status within a particular amount of time, say 6 sec.

### Human: convert PowerFlex 40 PROFIBUS to ETHERNET-IP Hi, Do you know if it is possible to convert (or add a new comms card) an existing VFD PowerFlex 40 that is PROFIBUS to ETHERNET-IP? Thanks Erik ### Assistant: Hi Erik, Have a look at the ProSoft EtherNet/IP to PROFIBUS DPV1 Master gateway. https://www.prosoft-technology.com/Products/Gateways/PLX5x/PROFIBUS-DP-Master-Slave-to-EtherNet-IP-Gateway CH \n


### Human: Powerflex 755 Register Addresses I am looking for register addresses for the monitoring values like voltage, current, power etc. I am going to pull these values through modbus. In the programming manual, there is only the addresses which can be used in Rslogix, Devicelogix or Studio5000 through some port numbers. I need the actual registers addresses where these value has been stored. ### Assistant: Rockwell has this technote about communicating Modbus RTU to a PF750: https://rockwellautomation.custhelp.com/app/answers/detail/a_id/493213 To do so requires a 20-750-20COMM card carrier and a 20-COMM-H communications card. I'm guessing though that you meant Modbus TCP (Ethernet)? \n


### Human: power flex drive 753 failure after power recycle We have using approx fifty power flex drives in our plant and have had little trouble until the other day. We had a scheduled power outage with the power company they disconnected all phases at on time and repowered us after one hour. after that we noticed we had one drive 55 kw rating that did not power back up and are fed from the same line as ones that did. we checked voltage at the drive line input and is fine. we are at a loss as what and why this has happened. ### Assistant: Do you get absolutely nothing? No cooling fans, no HIM light, nothing at all? Have you inspected the interior of the drive? Has a capacitor failed catastrophically or vented (look for goo where no goo should be)? Do you have a spare control board? Install that and see if the drive powers up. \n


### Human: Easiest way after replacing a VFD to add the parameters via a .DNO file Summary: Can this be done thru Studio 5000 without going thru Drive ExecutiveWe have .DNO file saved in Drive Exc. I've seen a couple way of doing this, and each time there has been minor hiccups. So is it easiest to download the .dno file through drive executive then connect through the PLC and do the match drive. We have Studio 5000 V30. Or can you go through 5000 and do the right click on the drive tab of the drive in question and use the import drive data ? If so do you have to be offline/ online with the drive when doing this ?? ### Assistant: Any suggestions or procedures that works best with Allen Bradley VFD's , Studio 5000 and Drive Executive as the platforms being used........Thanks \n

### Human: Use Independent encoder for position Summary: Encoder input to motion controlMy machine has a servo to control vertical motion, but the vertical load is on a belt that winds up on a wheel. The position of the vertical part is not very precise using the drive servo due to belt stretch pending the amount of load. The machine manufacture added an sick string encoder to help with position. I thought about using a MAPC, but the belt stretch from weight and distance spooled out is too much varibility. My question - how do I use this independent encoder to control position? I would like to send the servo to a setpoint and the servo slow down and stop at said setpoint, I assume, using one of the Studio motion functions. The encoder input is a 4-20mA analog input. Programming in Studio V32 Thanks. ### Assistant: Is there any chance of getting the machine manufacturer to change the string encoder from 4-20 analog output to an actual encoder output? I know Sick makes an SSI string encoder. What is the servo you are using? If it is one that has an auxiliary encoder input, this problem becomes very easy. \n


### Human: Servo compatibility Is the servo 1326AB-B720E-M2 compatible with Ultra 3000 and Kinetix 6000? ### Assistant: If the motor catalog number ended in -M2L then it would have a Stegmann Multi-turn absolute feedback encoder. It would be compatible on a 460V drive. The motor is rated at 6.8 kW. \n


### Human: back up from 1394 Digital AC Multi-Axis Motion Control Summary: back up from 1394 Digital AC Multi-Axis Motion ControlHi. I want to back up program ,setting and configuration from 1394 Digital AC Multi-Axis Motion Control. I can communicate with using serial port. but download and upload icon aren't active. How can I active UPLOAD icon? ### Assistant: It might be that you need a license for this software. Alternatively, you may have to SAVE before you can do either. It's been a very long time since I've touched GML. \n

### Human: VPC Control With Powerflex 755 Summary: Can a Powerflex 755 control a VPC servo motor in an electronic gear configuration?I'm looking for a solution to synchronize a servo motor to a master encoder. The servo motor is fairly large (22kW) and an MPL motor did not match all the needed specifications. I know a 5700 drive is ideal for a VPC servo, but this needs to be a standalone configuration. In the past I've done this with an AC motor and two encoder cards in the Powerflex 755. Is there any reason why I should not do this with a Poweflex 755? ### Assistant: nan \n


### Human: 843ES Safety Encoders - Position Error Summary: 843Es Encoders give position Error between two EncodersWe are testing the new 843ES Safety Encoders. We are finding that there is a significant error in position count value between two encoders, even though they are bolded to the same shaft. And no, one is not slipping, these are being turned slowly by hand. The 2nd unit is configured anti-clockwise to the first as clockwise. We did an extra test where both are clockwise, and there seems to be minimal error, however when the 2nd one is set to anti-clockwise, then error is introduced. Can Rockwell please advise the issue? And the release of updated firmware for the 843ES Encoder? Mike. ### Assistant: Michael, this is not Rockwell Tech Support. If you're expecting an official answer from Rockwell, you may not get it here. This is Rockwell's user forum, users helping other users. You should contact Rockwell Tech Support directly. \n


### Human: Powerflex 525 Forward / Reverse Summary: Control Powerflex 525 in forward / reverse directionCan i control powerflex 525 in forward/reverse direction just start command ( Hardwired DI) and speed reference ( 4-20ma only ) that shall corresponding to -50Hz to +50Hz such that when i give speed reference 4mA and start command drive shall rotate in reverse at full speed and when i give 20mA it will rotate in forward direction or i need separate forward / reverse command Drive is not communicating to PLC over ethernet or any other protocol ### Assistant: The only way you can get what you want is to use the analog voltage input. It will not work with the 4-20ma current input. If you can change to analog voltage, then you would set parameter t093 to value 1 (Bi-Polar In). According to 520-UM001: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/520-um001_-en-e.pdf, page 97, if you set t093 in this manner, then P043 (min freq) and t091 (anlg in 0-10V lo) get ignored. Presumably, with t093 set to bipolar, the 525 drive assumes your speed control is going to be symmetric (whatever you put in for max frequency and analog 0-10V hi) will be the same in the negative direction. \n


### Human: F004 Fault on Powerflex 4M Summary: Inverters faulting on F004 during ramp-upHi all We have 4 inverters fitted in this particular panel are all failing on F004 as the individual motors are running up (only two motors run up at a time). They are reading 400V-405V at the inverter input terminals. I believe the fault level is based on the based on the drive rating (480V) and is a non-settable threshold. We lowered P001 to 380 and switched the display to D005 (DC Bus Voltage) and the display started at 575V and, when it fell over in F004, it read 555V. This seems some way off the 390V stated in the Supplementary Drive Information you forwarded me. Do you know and could you suggest anything else that could contribute to this? Thanks Stuart ### Assistant: 555V bus voltage would correspond to a theoretical line voltage of 392V. I think you should look harder at your line in voltage. If you can put a power monitor on it, you might find the voltage is sagging far more than you can read with just a multimeter. Also, what is P001? That is not a valid parameter for PF4M. Did you mean P101 motor name plate voltage? Are you measuring voltage as the motors run up? It sounds to me like your voltage source is very soft and not up to the load. \n


### Human: ultra 3000i E022 fault Summary: drive trips after running awhile.I have an Ultra 3000i indexer drive, will run quite a few cycles then trips E022. this just started on an existing system thats run fine for years. Motor is cold to the touch. no brake in motor. N-3412-2-H00AA. Mechanical gearing seems fine. no drag. Online with ultraware v 1.8 wont let me shut off software protection, as i figure its the default parameters for that motor. any ideas to prove drive,motor or mechanical is the issue??? or how to disable the software protection? ### Assistant: E022 is Motor Thermal Protection Fault, and it is apparently calculated. It is different than E04, which is motor overtemperature. E04 comes from the motor thermostat on pins R and S of the encoder cable. I do not think you can disable this fault. Are you sure the motion parameters have not changed recently? Did someone change the accel rate without your knowledge, or decrease the time of the move? You do say that it takes quite a few cycles before it trips. After the first fault, does the fault reoccur with increasing frequency? I would check power lead connections from drive to motor for tightness or thermal discoloring. \n


### Human: Powerflex 525 No Jog Reverse Summary: Jog Reverse not workingHi all, I have a Powerflex 525 hardwired for jog forward on Dig in 3 and Jog reverse on Dig in 5 , Jog forward works fine ,Jog reverse does not work. There is no frequency output and Dig in status shows there is an input at input 5 , If i switch the jog functions to Dig in 5 Forward and Dig in 3 to Reverse the forward works fine on Dig in 5 and the reverse does not work on Dig in 3. It seems jog reverse does not work at all on any input.Thanks ### Assistant: What is parameter 544 (reverse disable) set to? What is parameter 93 set to (10V bipolar enabl)? \n


### Human: 8720MC F1 fuse blown Summary: 8720MC Regen Power supply keeps blowing F1 fuseWhat do I need to look at for possible causes for the F1 fuse blowing? Is it something inside the Power Supply, or wiring on the outside? We have a master unit and a slave unit and it blows both of them. ### Assistant: nan \n


### Human: PowerFlex 755 and IPM motor with an encoder Summary: Can’t control the speed of a permanent magnet motorHi, I am trying to control Internal Permanent Magnet Motor (not experienced at all) with Powerflex755 drive and I am lost. Today last thing I was successfully able to do was direction test and auto tune for rotational test. But after that once I started commanding the speed, drive couldn’t hold the speed at desired speed. The status would show constantly changing into accelerating, at reference and decelerating (what is the reason for this?)And it would fault as input phase loss. I received other faults too while trying lots of things and it turned into a mess. We are commanding the speed using a 0-10V analog card. The permanent magnet Baldor motor has a continuous rated speed as 1800RPM. And it’s maximum safe speed is rated as 5000RPM on the data plate. I was using CCW wizard to tune and start the drive. My question is: I set the speed reference as: Speed reference: Port5,Param Anlg In0 Value Speed ref A high: 1800rpm Speed ref A low: 0rpm Analog in Hi: 10V Analog in Low: 0V Analog Out 0 as: Select: Port 0, Param Mtr Vel Fdbk Scaling: Value High: 5000, Value low: 0 Range High: 10v, range low: 0v Attached are the screen pictures from ccw. I can add more pictures if needed. Should the scaling be 1800 since it’s the rated rpm? But I will need to run it at maximum safe speed... I tried changing speed reference from 1800 to 5000rpm but it doesn’t accept any value more than 1800rpm. Any thoughts would be highly appreciated. I’m lost... Thanks in advance ### Assistant: What is the value of parameter 35 (motor control mode)? What are the values of parameters 25 through 31 (motor data)? What is the value of parameter 125 (primary velocity feedback select)? \n


### Human: Powerflex 700 Cat. No. 20BD040AYNADC0 Summary: powerflex 700 drive voltage ratingHello, I have a Powerflex 700 Cat. No. 20BD040AYNADC0 series B, that is suppose to be rated for 480V input. I was in process of programming the drive to run a 460V/60Hz 30HP motor. but the drive seems to think it is rated for 400V input. Is there a way to change this, so the drive knows it should be rated to 480V? The drive label is attached. so is an image of LCD on the HIM. The drive was repaired by replacing the 313489-A06 board with a new one. The motor (nameplate is attached) that I am trying to run was ran by the same powerflex 700 unit . Thanks. ### Assistant: Parameter 202 is Voltage Class; it should be set to HIGH (value 3) for 480V. It's probably set to LOW (value 2) for 400V. If that's not the solution, then what is the value of parameter 54 (maximum voltage)? \n


### Human: Kinetix 5700 single turn encoder Summary: how to retain single turn encoder value after power cycleHow to retain Encoder value of single turn encoders to simulate as Absolute Position Encoder at power cycle event in Kinetix5700 drives? What is the tag for single turn encoder value feedback on kinetix5700 drive? ### Assistant: There is axis.ActualPosition; this element is going to be in user units defined by your scaling in the axis properties page and will be type REAL. In the axis properties page, Drive Parameters branch, Parameters to be read each cycle, there is a PositionFeedback1 entry. If you check that box, it gets added to the axis tag elements. This element is type DINT. This is not what you need though. You have a servo motor with incremental encoder attached to a K5700 drive. You have to set up scaling in the axis properties page. The Logix processor running this axis is going to work in user units, so axis.ActualPosition is all that you need. In the axis properties page, HOMING branch, set homing mode to active and immediate. Position doesn't matter so leave it at 0; you're going to overwrite the position. Motion will not occur when you issue an MAH with this configuration. use a MOV command to store axis.ActualPosition in tag LASTPOSITION, with logic that allows this MOV only after a startup routine has completed. This instruction should scan every PLC scan. On first scan, clear the bit that says startup routine has completed so that you do not lose LASTPOSITION. Have your startup routine issue an MAH. The axis.axishomedstatus bit gets set. When the MAH.PC bit goes true, issue an MRP with position LASTPOSITION. When the MRP.PC bit goes true, you can now set your startup routine complete bit so that the MOV instruction above begins storing the position again in anticipation of the next power cycle. The axis position is what it was at the final scan before the power cycle. \n


### Human: powerflex 525 using parameter A484 Summary: am I using para A 484 correctlyA 7.5 kW 4 pole 400 v centrifugal turbulence fan in an gas oven trips if temperature of the air is too low. It is controlled from a powerflex 525 inverter. Can I use para A 484 to limit current and also output rpm. If not, how can I control the current during low temperature to stop the drive from tripping? ### Assistant: Yes, A484 is intended to limit current lower than the motor overload current of parameter P033 that would otherwise cause a motor overload fault. Because you're using a PF525, you actually have two current limits to work with (A485). You would use a terminal block input to switch between the two current limits. With one parameter T062-T068 set to value 26, when that specific input is turned on Current Limit 2 defined in A485 sets the drive current limit. \n


### Human: Motor starter information Summary: Looking for product specifications and interconnect diagramHello, We have had a particular product that was specified to us for a new system we are building and I cannot find any information on it other than a replacement parts list. The part number that the company gave us is 505V-AOXWD-104 motor starter. Would there be a manual for this product? If so could you give me a link or forward the info? Thank you for any help you can provide. ### Assistant: I suggest starting with these two links. The part number you gave looks a little odd. The 'D' would usually follow the 'AO', meaning a 120v coil. I can't figure out the overload part of the number. I'm not real familiar with the NEMA components. http://ab.rockwellautomation.com/Motor-Control/LV-Starters/NEMA http://literature.rockwellautomation.com/idc/groups/literature/documents/ca/a117-ca902_-en-p.pdf \n


### Human: Motor is stuck during runtime Summary: Motor is stuck during runtimeMotor is drove by PF755. But during runtime motor isn't smooth, got stuck. Autotuning is done. Also change PF mode to VF control. ### Assistant: Gene, we need a LOT more information. What is the basic application (what is the load you're trying to move)? What is the motor nameplate data? Does it have encoder feedback? Did you enter the correct number of poles? When did it get stuck? At low speed? High speed? Did it follow speed commands at all? If you have a DNO file from DriveExecutive or whatever file format CCW uses, you should upload it. Uploading a DNO file for us to view along with correct motor nameplate information will get you the best support from your fellow users. \n


### Human: PF755 master/follower application - recommended encoder Summary: single channel / single ended or dual channel / differentialHi, I have an application in which I am hoping to use two PowerFlex 755 AC drives in a Master / Slave relationship in a roll-to-roll web handling application. My plan is to equip the master drive with a 20-750-ENC-1 single incremental encoder module and to equip my slave drive with a 20-750-DENC-1 dual incremental encoder module. I will have an encoder mounted on both the master motor and on the slave motor. I plan to wire the master encoder to both the master drive (as feedback for the controlled master motor) and to the slave drive (as an external reference). I will wire the slave encoder to the slave drive (as feedback for the controlled slave motor). I am hoping to use the electronic gearing feature to ensure that I can run the slave motor at a fixed ratio of the master motor. Ideally, I am hoping that I can achieve good performance (in terms of accurate speed control without motor cogging) within a 100:1 speed range (motor RPM ranging from 18 - 1800 rpm). With this in mind, I am planning to use a high quality vector duty motor. My application is basically a constant speed application, where the master roll and the slave roll are used to convey a continuous web material through a machine. The speed ratio is nominally always 1:1 because if the rolls do not turn at the same speed, it would either create slack between the two rolls or break the web. This being said, I do need the flexibility to adjust this ratio between approximately 0.998:1 and 1.002:1 to compensate for stretching or shrinking of the web material in a dryer that it passes through. I *think* there is a good chance I would be able to get the performance I want with independent drives (not using electronic gearing) by just entering set points in the desired ratio, using the same acceleration/deceleration settings for both drives, and making sure I issue start and stop commands for both drives at the same time. The reason I'd like to try the electronic gearing feature is because I think it might help me do a better job of coordinating the speeds of the drives during acceleration and deceleration. I figure if it turns out not to be unnecessary, I will only have wasted the extra cost of one dual-encoder module and hopefully I will have learned something about the electronic gearing feature that might help in future, more challenging applications. My question for today is, will single-ended, single-channel encoders of appropriate resolution be sufficient for achieving good speed control? Or will there be some advantage to be gained if I consider using dual-channel, differential encoders? Any advice or suggestions will be greatly appreciated. Thanks and best regards, Paul ### Assistant: Consider using an encoder splitter on the master encoder signal - master encoder goes into the splitter; output1 goes to the master drive, output 2 goes to the follower drive. https://www.motrona.com/en/products/signal-converters/level-converters-signal-splitters/gv210-pulse-switch-distributor-and-splitter-for-incremental-encoder-signals.html I think I'd go with differential encoders myself. In all other respects, you've got it wrapped up pretty well. \n


### Human: MAPC with Rotary axes Summary: following axis will not continue in a forward directionI am attempting to have a servo motor follow a CIP encoder in essentially a 4:1 ratio, but with two dips in the profile. I have the CIP encoder set up in degrees and to rollover at 1440 ( 4 x 360 degrees ), I have the servo set up in degrees and rollover at 360. Using the MAPC camming, I have the first column in the profile going from 0 to 1440 and the second column is the follower positions in the range of 0 to 360. The MAPC is set up for Continuous, & Forward. The MAPC locks into position, but the following servo motor rotates around, then quickly rotates in reverse and begins again. ? Any way to have the following servo continue around rather than reversing.? ### Assistant: I think your problem is because of cam element #3 and #4. Take a look at this image, which uses the data you shared. Look at the weird blue spike that goes below zero on the horizontal master axis at master position 460. \n


### Human: Powerflex 753 displays shows no voltage output or speed feedback in rpms or hz in torque mode min... Summary: replaced a PF700 that showed speed and voltage in torque modewe replaced a old PF700 that went bad. upgraded with a PF753. we no longer can see speed feedback in rpms or hz or voltage output in torque mode. this application is used as a nip roll in a paper machine wet end. we see it running, showing 30 amps output. it shows -0.75 hz with the arrow negative on the HIM. it has a pot for torque reference . it has a positive torque reference. machine seems ok but just wondering. the PF700 used to show speed and voltage output. Is it ok or do we still have a problem. we used to run at 78% torque reference but now only at 28%. if we turn up the torque pot to what we ran at before it trips on overload. ### Assistant: here is a drive observer picture what we see, estimated rpm about 1400 \n

### Human: 1395 DC Drive excessive field voltage Summary: field voltage to high, motor overheatingI have a 460v 1395 dc drive, motor field rated at 303v , the drive is giving it 425v causing the motor to over heat. Is the any way to adjust the field voltage? ### Assistant: nan \n


### Human: Powerflex 750 DeviceLogix program error on upload in CCW Summary: Trying to safe drives to a project but keep getting DeviceLogix program error on upload So I am running Multiple 755 Powerflex drives. I am trying to make the switch from Drive Exec to Connected Components Workbench. I can connect to the drives and do a preliminary upload. When I try and save the drive to the project, and do a complete drive upload, it appears that all the parameters are uploading but I get an error for DriveLogix program upload. I have DriveLogix disabled, and no program in the drive. I am connecting thru eithernet IP, via a Stratix 8000 connected to the drive. Has anyone had this problem before, or does anyone have a suggestion on how to fix this? ### Assistant: I apologize for being one of those people who ask questions, but don’t provide answers. However, some more information is needed to be able to help. In order of importance, some useful information would be: - What is the error? (Click on the blue circle next to the progress bar if no error is shown.) Provide a screen shot of the error. - What is the version of the drive? - What is the version of software? - If DriveExecutive works, upload the drive from there and provide the saved file. - A bunch of random information can be gathered by running the “DPI/DSI Tech Support Wizard”. Connect to the drive, run that, and provide the text file. \n


### Human: PowerFlex 525 won't communicate with CCW or Logix 5000 Summary: PowerFlex 525 communicates with controller but not CCW or Drive tab in Logix 5000Hi Guys, I seem to have an issue communicating to my PowerFLex 525's via CCW or the drive tab in Logix 5000. I'm trying to change some parameters. I have 5 drives and all of them do the same thing. The PLC is able to communicate without issue. Can anybody think of a reason why my PC is being blocked? Thanks ### Assistant: What do you see in RS-Linx? Do you see all devices there? Is this the first time this computer has used CCW to communicate with Rockwell devices over Ethernet? It's possible your computer's firewall is blocking CCW. What PLC is working for you? Can you talk with that successfully? What version of CCW do you have? Have you installed the latest drives database for CCW? \n


### Human: Looking for a name of a part Summary: Trying to figure a name and a function of a part in clients el.cabinetHello!

### Human: PF 525 Displaying F099 Fault Code Summary: I have a PF 525 Showing F099 5.001 rev According to the documentation this is not possibleSee the image attached. I cannot find any documentation that references a PF525 showing this fault code anywhere. Please advise.. we use a 25-comm-e2p module with this unit. and S2 and 4 are the only IO. ### Assistant: It's reporting local weather - Fogg. You're going to have to call Rockwell Tech Support for this one - you're right. It's not a documented fault code. I looked hard through the knowledgebase. F099 by itself brings up nothing. The knowledgebase is performing to Rockwell standard, meaning using search terms +Powerflex +525 +Fault +Codes does not bring up useful results. Call Tech Support. When you get an answer back, would you please share it here? You've got my curiosity up and I'd love to know the answer. \n


### Human: SMC-50 Underload Fault Reset Summary: Cannot reset Using PLC tag, but can reset using drive tab or keypadHello. I am having an issue with a SMC-50 Soft start. The drive has been added to the IO tree of an rslogix application and I can communicate to the drive and I can see status information and also set up certain parameters from the PLC. One thing I cannot do however is reset an underload fault using the clearfault output bit (which is automatically created when adding an SMC-50 addon profile) in ladder logic, however I can reset the fault if I either go on to the SMC-50 drive tab in the PLC application and “clear faults” or from the in built key pad on the front of the MCC. I don’t have to set anything up within the SMC-50 using components workbench do i? I was able to set fault enable outputs directly from the PLC, I just cannot clear a fault using the logicCommands_Clearfault tag. What is the difference in the soft starter between using the “logicCommands_Clearfault tag” output tag or selecting “clear faults” on the alarm section of the drive tab in the IO tree of the plc application. Any help would be appreciated. Note: using 20-COMM-ER module on the drive to communicate to the PLC, no set up using components work bench on the drive itself ### Assistant: How long are you setting the P2_046_MCC:O.LogicCommand_ClearFault bit in your PLC code? If you're issuing a 1-shot to do this, that's probably not long enough for the signal to get passed via Ethernet. Can you hold it for 1 second? Share a screen-shot of the OTE that calls this tag. \n


### Human: Powerflex 700s VFD Running but Motor is NOT Summary: VFD shows running but motor not turningWhen the VFD is issued a run command it goes into run mode, the HIM module shows increasing DC bus and Output Current, but the RPM is bouncing in the + and - range, the direction is also bouncing from FWD and REV. It seems that it is trying to start the motor, but the motor stays still, and the VFD does not go into fault. Looking to find out what is causing this. The VFD is 600VAC, 208A and was installed in 2006. ### Assistant: Does this motor have an encoder on it for full flux vector control? Did anyone touch the wiring of this system between the time it did work properly and now? \n


### Human: How to get supplied electrical Power to a motor on Kinetix 5700? Summary: Trying to get the electrical power supplied to an axis.I am trying to measure the supplied instantanious and average electrical power for an axis using Kinetix 5700 parameters. I searched the manuals but didn't find a parameter that would do this. So the question is if there is a way to get the power supplied to the motors from the drives parameters? The used servo motor is a vpl low inertia motor. ### Assistant: You can get the (instantaneous, I think) power for an axis using a GSV command. Look at this document: https://literature.rockwellautomation.com/idc/groups/literature/documents/rm/motion-rm003_-en-p.pdf Go to page 369 of the PDF for power. \n


### Human: Power Flex 755 intermittant comm loss Summary: Drive stops communicating randomlyCurious if anyone else has had this issue with the imbedded Ethernet cards on there 755s. This drive is part of a skid where the 5 drives work together off a master drive. And the drive runs fine but it looses communication intermittently and kicks the operators out of auto and makes them use the machine in manual. Ive tested the Ethernet cable going to the drive, ive changed the main control board, plugged the cable into a different port on the Allen Bradley switch to no avail. Ended up changing the whole drive out which fixed it. I am curious what would cause an intermittent issue like this? Any insight would be appreciated ### Assistant: No good answer. Changing out the main control board should have done the trick. It's possible the drive back-plane was bad. We've seen this once I think, and I think someone else commented on this in the forum. You've got it solved this time. I do not think it is a design defect. You say you tested the cable. Did you flat-out replace it? Was the cable commercial, or did you make up both ends? Was the cable rated for 600V and double-shielded (foil and braided shield)? \n


### Human: Unable to get Ethernet Comms working on Dual Port Ethernet Module - PowerFlex 525 Summary: Dual Port Ethernet Communications Setup ProblemsWe have a problem communicating to our PowerFlex 525 drives using the dual port ethernet interface from the stratix switch. Communication is OK if we use the embedded ethernet port. However, when we connect to the dual port interface we cannot ping the drive. Any thoughts? ### Assistant: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/520com-um003_-en-e.pdf That's the user manual for the dual port Ethernet manual. Did you install it correctly? Did you install the interface connector that connects the card to the drive? It's easy to forget this part; it does not look important. How did you configure the ethernet address of the dual part card? Did you plug your Ethernet cable(s) into the dual port card (not the embedded port)? Sorry, these sound like stupid questions, but I've encountered an instance where each question was someone's solution. What do the card's LED status indicators show? \n


### Human: kinetix 5500's Summary: MAM will finish after an interrupt instead of executing new MAMI have run into an interesting issue. When i break the light curtain while my machine is in motion, safe torque off activates and the program holds that position until a return to home command or continue cycle is initiated. this is normal operation. On this machine though, i have found MAM's still enabled even if the rung isn't true anymore, and the drive will finish the motion that was in progress instead of executing the return to home MAM. is there a way to clear the memory of the drive in this situation so i can be sure it executes the MAM the logic dictates? as of now, the drive is not following the logic of my program. i have looked at scan times, made sure that my routines were being read in the right order, checked for duplicate MAM's and OTE's, made some logic very unique to ensure it wasn't duplicated in other places. i have worked on this issue for two days and not had any luck. processor is 1769-L27ERM-QBFC1B mated to 2198-H070, H008, H003 - ERS. Studio5000 version 30.11 I have 4 identical machines that were just built and all exhibit same behavior, so i'm certain it is in my program, but i cannot find the bug in the code. i have built 30+ machines like this but have never run into this issue before. ### Assistant: Gregory, you're far more likely to get a useful answer if you share your ACD file and point us to the location of the MAM that persists. \n


### Human: Configuring 527 for fan motor application I am currently adding a 527 drive to a L71S PLC via ethernet. I am trying to configure the motion group and I need to know what settings I will need in setting up the axis. ### Assistant: If you already have the drive configured in the IO tree, you should also have an axis associated with it. In the motion group folder, create the motion group using right click / create. Name is unimportant. Move the axis from the ungrouped folder to your new motion group. Doubleclick it to open its property page. You've given us little information to go on, so I'm going to make wild assumptions on what you have - like, no feedback. General tab: Axis configuration - pick frequency control Motor tab: Data source - nameplate data sheet motor type - rotary induction Fill out the motor parameters. Do make sure you get pole count correct - Poles = 120 x base frequency / synchronous speed Analyser tab: Run this after you have wired, powered, and communicating. Dynamic test by preference, but static test will work. Hookup test tab: Use that to verify correct rotation Frequency control tab: Go with defaults until you know what you want to adjust. Drive parameters tab: Pick what parameters you want to have access to read and write. You cannot have them all. Pick the monitoring ones that make sense for your application to display on an HMI. \n


### Human: Using a VSD with a Demag conical brake motor Summary: Demag Conical brake motor can be used with an ABB ACS 800 drive, is there a suitable Rockwell productA Demag conical brake motor can be used with an ABB ACS 800 drive. Is there any AB Powerflex Inverters which are suitable for this task? ### Assistant: We've actually done this with PF753 drives, without knowing before hand that the motors were conical rotor. The crane bridge had 6 motors running off one PF753, and it worked surprisingly well. Only at the slowest speeds did the rotors not release. It took some tuning of parameters P60-P63 to get something the operators thought was good. Never mind that it was VERY qualitative and I think they said one test run was better than another despite the fact that we'd not changed anything that time. \n


### Human: PF7x and PF5x analog input filter Hello RA guys! I'm looking forward to energy reduction on one site - consequentially changing motor control mode (P ### Assistant: For the PF525, refer to the user manual: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/520-um001_-en-e.pdf See page 99 for parameter t099 - analog input filter. A similar parameter should be available for the PF7x. \n


### Human: 2HP PF755 Motor Speed Varying with Encoder Feedback Summary: Closed Loop Speed Control is PoorHello. I have been getting beat-up by this drive path over the past few weeks. It is a 2HP/480V/1750rpm application with a PF755/2HP connected to a known well-performing Marathon Blue Max 1024 Quad Encoder-Feedback motor taken from another line during troubleshooting. 150W brake resistor is connected. Control is entirely over Ethernet. This motor goes through a ~20:1 right angle gearbox with an output driveshaft down to a small meltpump. VFD cable is used to the motor with no terminations in-between. Control mode is Induction FV. Speed regulation is poor at +/-3% and load swings of +/-15% degrading to load swings of +/- 100%. Other paths with the same setup are rock-solid with very tight speed control - no deviation from set point is seen on the scada hmi. I have attached a video showing this. Motor/Encoder has been replaced, gearbox has been replaced. The speed control fluctuations persist even when disconnected from the load. The original new drive was just replaced with another new drive today. It has been Calculate, Static & Rotate tuned without successfully eliminating the speed hunting. Once again, the other paths on the machine are absolutely stable. Our process requires tight speed control. Any ideas where to look next? Thanks in advance, -dan ### Assistant: You did not say that you'd done an inertia tune, only the calculate/static/rotate tune that characterizes the motor winding. You need to do an inertia tune, and even after that, I suggest increasing the speed regulator bandwidth (P636). Assuming you use DriveExecutive or CCW, when you do the inertia autotune, after it completes it shows speed reg BW at the bottom. It never, ever changes this; the default I've always seen is 10 rad/s. After autotuning, before moving to the next page, change it. If you have a 20:1 gearbox. Try a value of 30. If that does not work, then go to P636 directly and increase it to 50. Also, be aware that, unless the drive was brand new / broke the box seal to install it, a drive previously used does not completely wipe itself when running the autotune wizard. We've found out the hard way that a drive autotuned for a small motor, then switched to a larger motor keeps some parameters that were appropriate for the small. We've found that you have to do a factory-reset ON THE HIM in order to clear out all parameters. Doing it from DriveExecutive / CCW is not enough. If your new drive was actually a drive new to the application but had been tuned to a different motor, that might explain some of your results. \n


### Human: powerflex 755 defaulting option card after brake slip alarm I had an issue yesterday during commissioning where we were testing the brake slip function and it worked and started lowering then stopping then lowering again. after 3 times of lowering and stopping it started to free fall. I manually set the brake and brought it back down and powered down the drive. when turned power back on the parameters for the I/O card were default and i had to invert relay O and set it up to work the brake again. the drive parameters were still fine. The drive firmware is 14.002 and the I/O card is a 2262C-2R with firmware 1.008 I am also controlling the drive over ethernet via compact logix studio 5000 version 30.11 with ADC turned on ### Assistant: Parameters resetting is not happening after brake slip alarm, it's happening after you cycled power. Because you're using ADC, the PLC is pushing its parameters over to the drive once the drive makes its ethernet presence known to the controller. Verify your i/o card parameter settings in the PLC I/O tree definition. \n


### Human: Kinetix 350 2097-V33PR3-LM Summary: Kinetix 350 2097-V33PR3-LM on single phase 208Will a Kinetix 350 2097-V33PR3-LM on single phase 208 drive a TLY-A2530 motor? Does the drive require all 3 phases? I keep getting a Feedback Loss. ### Assistant: You'll be power-limited but should be able to run the motor. Feedback loss is unrelated - you have a feedback problem. \n


### Human: KNX5100 Contactor Summary: connect a safety contactor on the power section without using STOHello. I am replacing an Old servo drive by a KNX5100 (2198-E1007-ERS).I want to turn on and off the safety contactor without the need of resetting an alarm or taking further action. Would you mind help me if: - connecting the power to a safety contactor - keeping the control module always powered - no breaking the STO wiring is this combination is correct? and will not harm the drive? any issuing of alarms that needs to be reset? many thanks for your help and support ### Assistant: If you're not breaking the STO wiring, you're missing the point of STO. I'm pretty sure there is a specification on the number of power cycles per hour that Kinetix drives should have; the STO circuit is there so you don't bump into that limit. You could potentially harm the drive with too many power cycles in too short a time. Use a safety relay in place of the safety contactor to control the drive STO circuit. As far as alarm/resets go, if the drive cannot be configured to self-reset after an STO event, you may have to add relays / PLC logic to do so. \n


### Human: Kinetix 5700 CONECTING state stuck Summary: The servodrive kinetix 5700 connected to a MPL-B680D-M motor first time setup.Hi I'm doing the first setup of a 2198-S086-ERS3 kinetix 5700 connected to a MPL-B680D-M motor and it has also a 2198-P070 servo power supply. It is stuck at the CONECTING state, the power supply also stop at the same state. I look the Logix Designer modules information and there is no clue of an error. ### Assistant: What else is in your Motion Group? Do you have another axis in the motion group where the drive is not physically present or the motor not connected? In Rockwell's implementation of CIP Motion, all axes must detect their physical drives / motors or you'll get stuck exactly where you are. To get around this, you can inhibit the missing drive in the IO tree. If a drive is inhibited, the Motion Group will ignore it. If the drive is not inhibited and is missing at the type of system power-up, you get the problem you have. \n


### Human: Kinetix 300 backup I've to go on a site where the end user would like me to connect to some Kinetix 300 drives there installed, to save a backup copy of the configurations. Do I need a special software / interface to connect? Thank you. ### Assistant: You need a computer and web browser which supports the JAVA that runs on the K300. Take a look at these two KB articles: https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/621621/loc/en_US https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/67516 They have some other useful article links. Point your browser to the IP address of the drive and MotionView will in theory start. If it does start, then you can use MotionView to archive the K300 program. If it doesn't start, you now must head down the rabbit hole of trying to make that Java work on your browser. #K300 #MotionView #Java \n


### Human: Ultra 3000i Tuning Issue Summary: Servo positions correctly has high pitch whine while holding position.I have an MPL-A430H-M servo on an Ultra 3000i Sercos Drive. Motor functions and positions great and has no instability and accurate positioning. In between cycling as it is holding it's position it has a high pitch whine. I have tried to tune this out by tweaking the gains through RS Logix in the Drive parameters. Despite attempting several manual adjustments to both Proportional and Integral Gains the whine persists with no apparent affect. Any suggestions on correcting this issue? ### Assistant: nan \n


### Human: Powerflex 753 Datalink Summary: Cannot configure datalnk 1 to read amps of driveI have a 20-COMM-PBUS card in port 6 of aPowerfles 753. In the host parameters of the option card I want to modify Par 17 Datalink 1 to read amps Par 3 of port 0. When ever I try to edit this parameter i get a DPI error, Object State Conflict ### Assistant: Isn't parameter 3 of a 753 motor velocity feedback? I see parameter 7 of port 0 as motor current. That said, I don't know why either of those would cause a state conflict. Is the parameter being used already in another datalink? Are you trying to set these while the drive is running? I don't think you can do that; drive must be stopped in many cases when editing parameters. You might try setting the parameter off line, then downloading to the drive (unless you're doing this through the HIM). I tested this using a 20-750-ENETR but I don't know why it would be different for a 20-COMM-PBUS. \n


### Human: comm failure Summary: 22-COMM-E card failure on powerflex 40PI have had several of these cards fail. Changing the comm card does'nt work. I have to change the card and the drive. Its not an IP issue with the replacement card. Not a firmware issue either. I had thought it might be the internal power supply in the drive for the comm card. Drive works from terminal strip or I can control from CCW. Any thoughts? ### Assistant: If you can connect with CCW to the drive, you're using a 1203-USB to do so? If you can see the drive using the 1203-USB, what does CCW tell you about the 22-COMM-E cards? Does it recognize that one is installed in the drive? \n


### Human: Powerflex 525 Output voltage Lower than rating Summary: Powerflex 525 Output voltage Lower than ratingHello, regarding the specs of the powerflex 525, if the output Voltage specifications says :0..460V, 3 Phases, I am guessing I can use this to drive a 230VAC motor? I have an application where I have 480VAC and a 230VAC motor. There are PF525 with 120VAC 1 Phase input, 3 phase 230VAC output but that requires to upsize my 120VAC transformer. If I can just put the 230VAC motor on a 480VAC drive, my transformer will keep a reasonable size. Thanks! Antoine ### Assistant: I would recommend reading this technote: https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/516206/loc/en_US Luckily, it is an article listed for everyone. Short answer is that it is theoretically possible but you're most likely going to burn up the motor. The 230V motor most likely will have insulation rated for 230V, not 460V. A stepdown transformer and 230V VFD is the correct solution for that motor. Alternatively, get a 480V motor to eliminate the stepdown transformer. If you decide to try using the 230V motor on the 460V VFD, let us know how well it worked and how long the motor lasted before frying (if it did). I'm not being facetious - you might learn something that all of us could use. \n
