  1. Static and rotate tunes populate the same parameters. Inertia tune is something completely separate and only comes to play in FV modes. The main difference of static vs rotate is the measuring of flux current. Static uses a lookup table whereas rotate measures it. You may need rotate tune for some motor types like pm for the offset tests for the encoder. You can run the master independently from slave but just know that they will become in un synchronized. Sounds like for your tables that won’t matter though. If it does, you’ll just have to rehome the master to re synch to slave
  2. SAFETY TAGS MANIPULATION

    You can manipulate tags with RSLinx used as a DDE or OPC topic. Is that what you mean?
  3. Positioning PowerFlex 525

    Can you place your .iuux file here?
  4. Powerflex 700s data

    Can you explain what inject a file to the 700s means?  Are you trying to download parameters?
  5. What drive are you using?
  6. Easiest thing is to compare parameter 1 and 2. If they match then revisit where the reference is coming from. If they don’t, use the block diagrams in the manual to see where the signal is being changed
  7. CCW V13.0

    Have you tried updating RSLinx?
  8. CCW Developer and Developer ESD

    ESD stands for electronic software delivery. It has to do with licensing and subscription. Logix has the same thing. I believe it has to do with the type of contract you have with Rockwell
  9. CCW V13.0

    What is your OS and version of RSLinx?
  10. Are you using managed switches?
  11. There is a tech connect tech note that explains more. It basically states what you are saying. Passive will not enable the axis but active will. More information in MOTION-RM003
  12. Can your coworker create the module offline? Just at a different version?

  14. If the revision or series is missing, the AOP is out of date. Go to RA pcdc and install the latest AOP for the aentr 
  15. PowerFlex DC Drive

    This file cannot be opened by itself. You’ll need to attach a ccwarc file or the entire folder zipped. This is likely a tuning issue. Have you followed the DC user manual?
  16. Sounds good. Having a ramp time of 0 is not really a good idea anyway. Glad to hear you’ve resolved it
  17. Does it occur in V/Hz mode? does this occur in Vector mode with the encoder set to open loop?
  18. Many things can cause this. I’ll start with some basic questions. Are you in vector mode? What v did you megger at? If you fault with no motor connected, meaning disconnected at the output terminals of the drive, it’s likely a bad VFD. Ground fault basically means a current imbalance and the drive assumes it’s going to ground. Start the drive with no motor leads in v/hz mode and measure output v. If balanced V then the drive may be ok but if unbalanced, the drive is for sure bad
  19. Use RA sample code to start https://www.rockwellautomation.com/search/ra-en-US;keyword=525;startIndex=10;activeTab=Sample_Code;spellingCorrect=true;facets=;languages=en;locales=en_GLOBAL,en-US;sort=bma;isPLS=false;sessionID=947f5258-279b-023c-2670-a5cd3e6ccc34;deepLinking=false
  20. Answer is maybe. Drive logix is like a plc. If machines are identical then maybe but you’d have to know the code. If you press start on the panel and the drive doesn’t start, my first step would be to see if the start signal is making it to the drive. It’ll have an io status as well as a logic status. If the bit comes on there then the issue is in the programming of the drive. If not then it’s wiring or the plc 
  21.  FV  closed loop mode uses slip regulation. All other modes use slip compensation. You can read about the differences in the manual on these. It’s just a hunch but try setting the flux up time to 0 secs in fv mode. Let me know if it faults in this case. And I haven’t heard of slip used from previous start. I have heard of flux being used from previous start. Try changing the flux current value and then back then start. Let me know if either of these tests work 
  22. An F12 should be resettable. Something else is going on. How big are these drives. How long before they fault after starting?  If you command 0 hz, do you fault?
  23. The 700S doesn’t support ssm. Both A3 and A6 have “changed parameters”. I still think the first thing to be done is to get the alarm code from the alarm queue. To be simple, run the tech support wizard and post it here. It saves the current status of the drive and all non default Params. I’ll be able to tell you what’s wrong from that 
  24. @Lacrim If there is an alarm on your HMI, then it would be whatever the programmer assigned for your HMI. To find out if it is a true drive alarm, check the alarm queue from the HIM. I'm not sure if you're using an A3 or A6 HIM. Either way, there will be an alarm queue. It has the record of the last 100 alarms (assuming it's not been cleared). if you clear the alarm queue, whatever stays is the current alarm. If you have a flashing STS LED, the alarm should appear there.
  25. Powerflex 700s

    You'll need to open the Drivelogix up. Drivelogix is basically a PLC built into the drive called 'DriveLogix' You need to connect to it and open the project to look at the I/O tree in RSLogix 5000. There'll be another ENET connection on the drive, other than an 20-Comm-E.
