Adjustment may help in the following situations:
• Increase this setting if the motor vibrates.
• Decrease this setting if the motor speed or motor torque responds too slowly.

No.
Name
(Hex.)
C4-03 Torque
Compensation @
(0217)
FWD Start
Compensation is applied using the time constant set in C4-05 [Torque Compensation Time].
Enable this function when starting the motor with a Forward run command. Setting 0 disables this feature.
■
C4-04: Torque Compensation @ REV Start
No.
Name
(Hex.)
C4-04 Torque
Compensation @
(0218)
REV Start
Compensation is applied using the time constant set in C4-05 [Torque Compensation Time].
This function operates only when the motor starts in the reverse run orientation. Setting 0 disables this feature.

C4-06 Motor 2 Torque
Comp Delay Time
(021A)
Sets the time constant used during Speed Search or during regenerative operation when ov occurs.
Adjust this parameter in the following circumstances.
• Gradually reduce the setting in 10 ms increments and check the performance to improve motor torque speed
response when when ov occurs.
Note:
• Ensure that C4-06 ≥ C4-02 [Torque Compensation Delay Time].
• Increase the setting value of n2-03 (AFR Time Constant 2) propotional to C4-06.

V/f CL-V/f OLV CLV AOLV
Sets the torque compensation delay time in milliseconds. Normally there is
no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the amount of torque reference at start in the forward direction as a
percentage of the motor rated torque.
V/f CL-V/f OLV CLV AOLV
Sets the amount of torque reference at start in the reverse direction as a
percentage of the motor rated torque.
V/f CL-V/f OLV CLV AOLV
Sets the starting torque constant used with C4-03 and C4-04 [Torque
Compensation @ REV Start].
V/f CL-V/f OLV CLV AOLV
Sets the value if ov [Overvoltage] occurs with sudden changes in the load,
at the end of acceleration, or at the start of deceleration.
