Setting a Torque Limit with Parameters
Torque limits can be set separately for the 4 ways that torque can be applied: forward torque, reverse
torque, forward regenerative torque, and reverse forward regenerative torque. These parameters can-
not be changed during operation.

Note When the torque limit function is engaged the torque control has priority and motor speed control
and compensation will be ignored, so the acceleration/deceleration times might be lengthened
and motor speed might be reduced.

Limiting Torque with Analog Inputs
The following two analog inputs that can be used to limit torque.
Multi-function analog input terminal 16
Frequency reference (current) terminal 14
Use either or both of these inputs as needed with parameters H3-05 and H3-09. These parameters can-
not be changed during operation.
