Ground fault protection
The drive is equipped with an internal ground fault protective function to protect the
unit against ground faults in the motor and motor cable. This is not a personal safety
or a fire protection feature. The ground fault protective function can be disabled with
a parameter, refer to the appropriate firmware manual.
The EMC filter of the drive includes capacitors connected between the main circuit
and the frame. These capacitors and long motor cables increase the ground leakage
current and may cause fault current circuit breakers to function.
