With these parameters, you can set 4 patterns of positive torque limits and 4 patterns of negative torque limits. Refer to 7.2 for the setting for switching from the terminal board.

Power running torque limit #1－ Power running torque limit #2－ Power running torque limit #3－ Power running torque limit #4－

Regenerative torque limit #1－ Regenerative torque limit #2－ Regenerative torque limit #3－ Regenerative torque limit #4－

Note) If the value set with  (stall prevention level) is smaller than the torque limit, then the value set with acts as the torque limit.

b) Limiting the torque with external signals

		＋250% torque
	Power running
	Regenerative
Reverse	Regenerative	Forward
	Power running
		－250% torque

The torque limits can be changed arbitrarily by means of external signals.
