Description
Motor-Slip Compensation
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.
This parameter adjusts the filter on the output of the slip
pensation function. Increase to add stability, decrease to improve
response.
This parameter sets the upper limit for the slip compensation
function. It is set as a percentage of motor rated slip (E2-02).
Determines whether slip compensation is enabled or disabled
during regenerative operation.
0: Disabled
1: Enabled
Determines if the motor magnetic flux is automatically decreased
when output voltage saturation occurs.
0: Disabled
1: Enabled
Torque Compensation
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
determines the amount of torque or voltage boost based upon motor
current, motor resistance, and output frequency.
This parameter adjusts the filter on the output of the torque
compensation function. Increase to add stability, decrease to
improve response.
Sets torque compensation at forward start as a percentage of motor
torque.
Sets torque compensation at reverse start as a percentage of motor
torque.
Sets the time constant for torque compensation at forward start and
reverse start (C4-03 and C4-04). The filter is disabled if the time is
set to 4ms or less.
