n63 : Torque Compensation Gain (K
T
) Factory setting: 1.0
Range: 0.0 to 2.5
Torque Compensation Gain ( n63 ) adjusts how
much the output voltage is boosted when motor
load increases. It is used to compensate for
resistive losses in the motor and the wiring
between the drive and the motor. Torque
compensation is only active when the Drive is in
the V/f control mode.
