C4-01
Torque Compen-
sation Gain
This parameter sets the gain for the
MxC's automatic torque boost function to
match the MxC's output voltage to the
motor load. This parameter helps to pro-
duce better starting torque. It determines
the amount of torque or voltage boost
based upon motor current, motor resis-
tance, and output frequency.
Adjustment is not normally required.
