The torque limit function is active in vector control mode. In V/f constant control mode, square
reduction control mode, and V/f 5-point setting mode, the torque limit function plays the same
role as the stall preventive function (6.25.2).
In torque control mode, the values set with these parameters limit torque command values.
(2) Positive/negative torque limits
First, you need to set the polarity of each torque limit. Set at .
