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 or CL-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.
Note:
-
Adjust C4-07 and make sure that the output current is not more than the drive rated current during low-speed operation.
-
When A1-02 = 2 [Open Loop Vector], usually it is not necessary to change this setting. If you change this parameter in that control method, it can decrease the torque precision.
