Adjusting the output torque (current) of the motor
4
PARAMETERS
(6) Limit the torque limit according to the operating status (Pr.156)
Refer to the following table and select whether torque limit operation will be performed or not and the operation to be
performed at OL signal output.
 When "Operation not continued for OL signal output" is selected, the " " fault (stopped by torque limit) is displayed and operation stopped.
 Since both fast response current limit and torque limit are not activated, OL signal and E.OLT are not output.
 The settings "100" and "101" allow operations to be performed in the driving and regeneration modes, respectively.

NOTE
When the load is heavy, or when the acceleration/deceleration time is short, torque limit is activated and acceleration/
deceleration may not be made according to the preset acceleration/deceleration time. Set Pr.156 and torque limit level
to the optimum values.
CAUTION
Do not set a small value as the torque limit level. Otherwise, torque generated will reduce.
Always perform test operation.
Torque limit during acceleration may increase the acceleration time.
Torque limit performed during constant speed may cause sudden speed changes.
Torque limit during deceleration may increase the deceleration time, increasing the deceleration distance.
