Ground Fault

What does F13 mean?

A ground fault has been detected, indicating an unintended current path from the motor phases or external wiring to ground. This protection prevents electrical shock and damage to the drive or motor.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Measure insulation resistance between each drive output terminal (U, V, W) and earth ground with the motor disconnected; expect a reading greater than 1 MΩ.

2. 4

   Inspect the motor cable and external wiring between the drive output terminals and the motor for any physical damage or signs of insulation breakdown.
