C4-07: Motor 2 Torque Compensation Gain
No.
Name
(Hex.)
C4-07 Motor 2 Torque
Compensation Gain
(0341)
RUN
Adjust the value set to C4-07 in small steps of 0.05 in V/f Control or Closed Loop V/f Control in the following
situations:
• Increase the setting value when torque is insufficient during low-speed operation of 10 Hz or less.
• Decrease the setting value when the motor vibrates or hunts while running the drive with a light load.
• Increase this setting when using a long motor cable.
Note:
• Adjust C4-07 so the output current does not exceed the drive rated current while running the drive with a light load.
• Normally, refrain from adjusting this parameter in PM Open Loop Vector Control. Torque accuracy is reduced.
■
C4-19: T-ripple suppress freq
No.
Name
(Hex.)
C4-19 T-ripple suppress freq
(0B8D)
Note:
This parameter is enabled when C4-20 [vol compensation adjust 1] is set to any value other than 0.
■
C4-20: vol compensation adjust 1
No.
Name
(Hex.)
C4-20 vol compensation
adjust 1
(0BCB)
Note:
Configure such that C4-20 = 0 when noise occurs during low-speed operation.
■
C4-21: vol compensation adjust 2
No.
Name
(Hex.)
C4-21 vol compensation
adjust 2
(0BCC)
Note:
Set C4-21 = 0 when noise occurs during high-speed operation.

C5: Automatic Speed Regulator (ASR)

The ASR adjusts the output frequency or torque reference to minimize the difference between frequency reference
and actual motor speed. The exact parameter that is adjusted depends on the control mode.
654
V/f CL-V/f OLV CLV AOLV
Sets the motor 2 gain for the torque compensation function when using the
Motor Switch function.
V/f CL-V/f OLV CLV AOLV
Increase the setting in increments of approximately 1.0 when current ripples
and torque ripples occur during low-speed operation. If this still does not
improve the situation, set C4-19 = 0 to disable this function. Normally there
is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
This parameter compensates the voltage accuracy. Normally there is no
need to change this setting.
V/f CL-V/f OLV CLV AOLV
This parameter compensates the voltage accuracy. Normally there is no
need to change this setting.
