I have an earth ground fault when the drive is on, however motor runs in bypass fine

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.

The frequency converter mechani- cally consists of two units, the Power Unit and the Control Unit. Pictures of the mechanical assemblage on pages 54 to 62. The three-phase AC-choke (1) at the mains end together with the DC-link capacitor (2) form an LC-filter, which, again, together with the diode bridge produce the DC-voltage supply to the IGBT Inverter Bridge (3) block.

The control keypad is used for parameter setting, reading status data and giving control commands. It is detachable and can be operated externally and connected via a cable to the frequency converter. Instead of the control keypad, also a PC can be used to control the frequency converter if connected through a similar cable.
