Ground fault

		Corrective Actions:
		When (one of) the output terminal(s) is grounded, short
		circuit current is more than 50% of AC motor drive rated
G r o u n d EFa u l t EEEE		current, the AC motor drive power module may be damaged.
		NOTE: The short circuit protection is provided for AC

		motor drive protection, not for protection of the user.

1.Check the wiring connections between the AC motor drive and motor for possible short circuits, also to ground.

2.Check whether the IGBT power module is damaged.

3.Check for possible poor insulation at the output line. Short-circuit is detected between upper bridge and lower
