Slip Compensation
Selection during
Regeneration
Selects slip compensation during regenerative
operation.
0: Disabled
1: Enabled
Using the Slip Compensation function during
regeneration may require a braking option to
handle momentary increasing regenerative
energy.

Output Voltage Limit
Operation Selection
Selects if the motor magnetic flux is reduced
during output voltage saturation.

Torque Compensation
Gain
V/f Control: Sets the gain for the automatic
torque (voltage) boost function and helps to
produce better starting torque.
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. Set the value so that the current at low
speed does not exceeds the drives rated
current.
Open Loop Vector: Sets the torque
compensation function gain. Normally no
change is required.

Torque Compensation
Primary Delay Time
Sets the torque compensation filter time.
Increase this setting when motor oscillation
occurs.
Reduce the setting if there is not enough
response from the motor.

Torque Compensation
Time Constant
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 4 ms or less.
