Torque Control - Magnetek Impulse G+ series 4 Instruction Manual

Torque Control

Please consult factory for application assistance regarding torque control. Typically, torque control
should not be applied on a hoist.
This function is used to avoid excessive changes in torque, which may be caused by abnormal
resonance when the torque reference changes rapidly.
