103
Adjustment:
Normally there is no need to change this parameter setting. However, adjust this setting by
scaling of 0.05 in the following situations.
·
Increase the setting when using a long motor cable
·
Decrease the setting when the motor oscillates
·
During running at low speed, adjust C3-00 to keep the output current below the drive
rated current
Note:
·
Do not change the setting in Open-Loop Vector Control as it will reduce the torque accuracy.
·
Do not change the setting in PM Open-Loop Vector Control as an excessive setting value could cause
overcompensation and motor oscillation.
C3- 02 Torque Compensation Primary Delay Time
Sets the Torque compensation primary delay time.
No.

Default
C3-02
Torque Compensation Primary Delay Time 0 to 10000 ms Determined by A1-02
Adjustment:
Normally there is no need to change this parameter setting. However, adjust this setting by in
the following situations.
·
Increase the setting when the motor oscillates
·
Decrease the setting when the response is slow
C5 Slip Compensation
The heavier the load is at IM motors, the slower the motor speed is. The Slip Compensation
function can improve the speed accuracy in such situations.
Note: Check if the settings of d2-00 (Motor Rated Current), d2-01 (Motor Rated Slip) and d2-02 (Motor No-Load
Current) are correct before adjusting this parameter. It is automatically set by Auto-Tuning in Open-Loop Vector
Control.
C5- 00 Slip Compensation Gain
Sets the slip compensation gain to improve the speed accuracy for heavy loads. Normally
there is no need to change this parameter. However, adjust the setting in the following
situations.
·
Increase the setting if the motor speed is lower than the frequency command.
