Posted 8 Sep 2022 Can anyone tell me how to check fault history in Allen Bradley powerflex 40 drive? Share this post Link to post Share on other sites
Posted 8 Sep 2022 Check parameters d007, d008, and d009 for the 3 most recent fault codes, with d007 being the most recent. Refer to the user manual too:https://literature.rockwellautomation.com/idc/groups/literature/documents/um/22b-um001_-en-e.pdf You may also be able to use DriveTools/DriveExecutive/DriveObserver to do some diagnostics too. It's been a long time since I opened those programs, so I can't help you much there. I seem to remember, though, that the software would give you more fault history than the parameters. I could be mis-remembering that, though. Share this post Link to post Share on other sites
Posted 11 Sep 2022 Connect with CCW. You can view the history there. It’s the latest drive software and free. Run the tech support wizard for print outs of parameters and fault history 1 person likes this Share this post Link to post Share on other sites
