C3-01
Slip
Compensation
Gain This parameter is used to
increase motor speed to
account for motor slip by
boosting the output
frequency. If the speed is
lower than the frequency
reference, increase C3-01. If
the speed is higher than the
frequency reference, decrease
C3-01.
Note: Adjustment is not
normally required. When
operating in Open Loop
Vector, this parameter
works as a function to set
the proper amount of
gain.
