Function
The function is to decrease or increase the output frequency according to the load
ing condition when the motor torque reaches the limit level.
Setting a torque limit parameter at 250.0 means "Invalid".
Setting
(1) Power running /regenerative torque limit
First, you need to set the polarity of each torque limit. Set  at .

a limiting the torque with internal parameters (or on communication mode)
Reverse
Torque limits can be set with the parameters  and .
