Ground Fault

What does Ground Fault mean?

The ground leakage current on the drive's output side has surpassed 50% of the drive's rated output current. This often indicates damaged motor or cable insulation, or excessive stray capacitance due to long cable runs. This condition poses a serious electrical safety hazard and potential damage to the motor or drive.

1. 3

   If long motor cables are used, consider reducing the drive's carrier frequency setting (C6-02) to minimize stray capacitance.
