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:

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.

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
