Torque
Compensation
Gain This parameter sets the gain
for the Drive's automatic
torque boost function to
match the Drive's output
voltage to the motor load.
This parameter helps to
produce better starting torque.
It determines the amount of
torque or voltage boost based
upon motor current, motor
resistance, and output
frequency.
Note: Adjustment is not
normally required.
