Output Voltage Limit
Operation Selection
Sets motor magnetic flux during output
voltage saturation. A setting of “1” will
automatically decrease the magnetic flux
when output voltage saturation occurs.

C4: Torque Compensation
Use C4 parameters to configure Torque Compensation function.
C4-01
<23>
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 sets the amount of torque or
voltage boost based upon motor current,
motor resistance, and output frequency.
Note: Adjustment is not normally required.
Make changes as follows:
Increase this setting when using a long motor
cable or when the motor is significantly
smaller than the drive capacity.
Decrease this setting when motor oscillation
occurs.

This value should be set so that
it does not exceed the rated
output current for the drive when
operating at low speed.
C4-02
Torque Compensation
Primary Delay Time
This parameter adjusts the filter on the output
of the torque compensation function.
Increase to add stability, decrease to improve
response. Note: Adjustment is not normally
required
Make changes as follows:
Increase this setting when motor oscillation
occurs.
Reduce the setting if there is not enough
response from the motor.
