text: <s>[INST] PowerFlex 700H F12 Overcurrent I have had a 700H for about a year now and started experiencing a F12 Fault on startup. When I had the reference at 30 Hz the drive would come up to speed and the current would be in the process of dropping off when the drive faults. The 400 HP motor is not in the best shape but I'm not convinced that there is not something going on with the drive. When I try to jog at 10 Hz, I see a quick spike in speed and current and then they both go to zero until the accel ramp time is done and then it will try to start up and eventually trip on F12.
