Cause : When (one of) the output terminal(s) is grounded, short
circuit current is larger than Pr.06-60 setting value, and
the detection time is longer than Pr.06-61 time setting,
GFF occurs.
NOTE: the short circuit protection is provided for AC
motor drive protection, not to protect you.
Check the motor insulation value with megger. Replace the motor if the insulation is poor.
Troubleshoot the short circuit.
Replace the cable.
