An earth ground fault in a Honeywell drive while the motor runs fine in bypass mode could be caused by insulation failure in the motor cables or the motor itself. Since the bypass mode does not use the drive, this suggests the drive detects the fault due to the current measurement showing an imbalance in motor phase currents, which indicates a possible ground fault in the motor or cables.
