H 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.
Parameter Display name p y
number
L7-01 Torque Limit Fwd
L7-02 Torque Limit Rev
L7-03 Torque Limit Fwd Rgn
L7-04 Torque Limit Rev Rgn
The following diagram shows the relationship between each parameter and the output torque.
Reverse
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.
H 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.
