Motor 2 Torque Compensation Gain

Sets the gain for motor 2 torque compensation function when using the Motor Switch function.

1.00

(0.00 - 2.50)

In V/f Control, adjust the value in 0.05-unit increments for these conditions:

  • When torque is not sufficient during low-speed operation of 10 Hz or less, increase the setting value

  • When there is vibration in the motor or when the motor hunts when operating the drive with a light load, decrease the setting value

  • When you use a long motor cable, increase the setting value.

Note:

  • Adjust C4-07 to make sure that the output current is not more than the drive rated current during low-speed operation.

  • When A1-02 = 2 [Control Method Selection = OLV], usually it is not necessary to change the setting. Torque accuracy will decrease.
