The slip compensation limit is constant throughout the constant torque range. In the constant power range it is increased based
on C3-03 and the output frequency as shown in the following diagram.
Note:
This parameter is disabled when using V/f Control with Simple PG Feedback Control (H6-01 = 3).

C3-04: Slip Compensation Selection during Regeneration
When the slip compensation during regeneration function has been activated and regenerative load is applied, it might be
necessary to use a braking option (braking resistor, braking resistor unit, or braking unit).
Even if enabled, this function does not operate when the output frequency is too low.

Slip Compensation Selection during Regeneration
0 or 1
0
Setting 0: Disabled
Slip compensation is not provided. Depending on the load and operation mode (motoring or regenerative) the actual motor
speed will be lower or higher than the frequency reference.
Setting 1: Enabled
Slip compensation is enabled during regenerative operation. It will not be active at output frequencies below 6 Hz.

C4: Torque Compensation
The torque compensation function compensates for insufficient torque production at start-up or when a load is applied.
Note:
Before making changes to the torque compensation parameters make sure the motor parameters and V/f pattern are set properly or perform
Auto-Tuning.

Torque Compensation in V/f
The drive calculates the motor primary voltage loss using the output current and the termination resistor value and adjusts the
output voltage to compensate insufficient torque at start or when load is applied. The effects of this voltage compensation can
be increased or decreased using parameter C4-01.
Adjustment
Although this parameter rarely needs to be changed, it may be necessary to adjust the torque compensation gain in small steps
of 0.05 in the following situations:
• Increase this setting when using a long motor cable.
• Decrease this setting when motor oscillation occurs.
Adjust C4-01 so the output current does not exceed the drive rated current.
n
C4-02: Torque Compensation Primary Delay Time 1
Sets the delay time used for applying torque compensation.
