C4-02 Torque Compensation Delay
Time
(0216)
RUN
Note:
If A1-02 = 8 [Control Method Selection = EZOLV], you cannot change the setting while the drive is running.
Set this parameter in these conditions:
• If there is vibration in the motor, increase the setting.
• If the motor speed or motor torque response is too slow, decrease the setting.
■
C4-07: Motor 2 Torque Compensation Gain
No.
Name
(Hex.)
C4-07 Motor 2 Torque
Compensation Gain
(0341)
RUN
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.
Note:
Adjust C4-07 and make sure that the output current is not more than the drive rated current during low-speed operation.

C5: Auto Speed Regulator (ASR)

The ASR adjusts the torque reference to decrease the difference between frequency reference and motor speed. You
can use this function only when you set A1-02 = 8 [Control Method Selection = EZOLV].
Note:
The detected speed is the speed estimation value.
■
Before You Adjust ASR Parameters
• Do Auto-Tuning and set up all motor data correctly.
• Always connect the load to the motor when you make adjustments.

V/f OLV/PM EZOLV OLV/PM
Sets the torque compensation delay time. Usually it is not necessary to change this setting.
V/f OLV/PM EZOLV OLV/PM
Sets the gain for motor 2 torque compensation function when you use the Motor Switch function.
V/f OLV/PM EZOLV OLV/PM
Current control gain. Usually it is not necessary to change this parameter.
