Ground Fault

Was bedeutet 13 ?

A current path to earth ground greater than 25% of the drive rating has been detected on the output. This indicates an insulation breakdown or short circuit between the motor phases or wiring and ground, which is a severe safety and equipment risk.

• Short circuit between motor phases and ground.
• Damaged motor winding insulation.
• Faulty motor power cable.
• Grounding issue within the drive or motor.

1. 1

   Check the motor for a grounded condition (e.g., measure insulation resistance from motor phases to ground).

2. 2

   Check the external wiring between the drive output terminals and the motor for a grounded condition.
