level flows for more than the			-specified time. Trip information is displayed as "				".
		(No trip) ...... No tripping (FL relay deactivated).
		An overtorque alarm can be put out to the output terminal by setting the output
		terminal function selection parameter.
		(Trip) .......... The inverter is tripped (FL relay activated) only after a torque current exceeding
		the	-specified level has been detected for more than the				-
		specified time.
