text: <s>[INST] PF525 - PM Motor - F013 Ground Fault Hi, We have a PF525 - PM Motor with Encoder running closed loop, and after changing Acc/Decel we faulted with a F013 Ground Fault. Now any motion will fault with F013. I've tried changing to open-loop with no feedback, same thing. I've disconnected the motor from PF525 and same fault. Any ideas? Thanks, Thomas [/INST] Have you tried tuning? See technote QA17876 Regards, RM \\n </s>
