Torque limit

6.25.1 Torque limit switching

• Function
This function is to decrease or increase the output frequency according to the loading condition when the
motor torque reaches the limit level. Setting a torque limit parameter at 250% means "Invalid."

Setting methods
(1) When setting limits to torque, use internal parameters (Torque limits can also be set with an external control
device.)
Torque limits can be set with the parameters
