n071 : Torque Compensation Gain (KT) Factory setting: 1.0
(Torq Comp Gain)
Range: 0.0 to 3.0
Sets the torque compensation, in increments
of 0.1. When the motor has the same
capacity as that of the drive, the gain is 1.0.
When a smaller motor is used, the gain
should be set to 1.5 (typical).
This parameter is used by the drive’s
automatic torque boost function to match
the drive’s output voltage boost to the
motor load. Except for the most demanding
of high starting torque applications, the
factory settings of these parameters will be
adequate. The factory settings are
programmed to match the performance
characteristics of typical AC motors.
The calculation of compensated torque
uses the following formula:
