Using parameters, four different torque limits can be set for each operating status: power running and regenerative braking. Refer to Section 7.2.1 for the setting for switching from the terminal board.

Power running torque limit 1 – ￿￿￿￿	Regenerative braking torque limit 1 – ￿￿￿￿
Power running torque limit 2 – ￿￿￿￿	Regenerative braking torque limit 2 – ￿￿￿￿
Power running torque limit 3 – ￿￿￿￿	Regenerative braking torque limit 3 – ￿￿￿￿
Power running torque limit 4 – ￿￿￿￿	Regenerative braking 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.

(2)When setting limits to torque, using external signals

Positive torque

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

Negative torque

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