How do I fix an F58 Current Measurement Fault code for a DG1 drive?

The current measurement fault is the control board monitoring the voltage bias on the current measurement circuit. If the biased voltage becomes greater than 7% it will cause the drive to fault. To handle this fault try performing a factory reset to the drive and reprogram the motor information, run the drive to see if the fault returns if so it would require replacing control board. It might be an induced voltage issue where it is intermittently faulting, verify all connections are properly tightened.
