  1. 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
  2. CCW V13.0

    What is your OS and version of RSLinx?
  3. PF527 syncronizing, not connecting

    Are you using managed switches?
  4. 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
  5. AOP installation broke module RSL5000

    Can your coworker create the module offline? Just at a different version?

  7. Creating module in Studio5000

    If the revision or series is missing, the AOP is out of date.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 
  8. 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?
  9. Powerflex 525 F013 Ground Fault

    Sounds good. Having a ramp time of 0 is not really a good idea anyway. Glad to hear you’ve resolved it
  10. Powerflex 525 F013 Ground Fault

    Does it occur in V/Hz mode? does this occur in Vector mode with the encoder set to open loop?
  11. Powerflex 525 F013 Ground Fault

    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
  12. Micrologix 1400 to Powerflex 523 on DSI

    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
  13. Powerflex 700s (Alarm condition)

    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 
  14. PowerFlex 755 F12 (HW OverCurrent)

     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 
  15. PowerFlex 755 F12 (HW OverCurrent)

    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?
