Torque Compensation Gain
V/f Control: Sets the gain for the automatic torque
(voltage) boost function and helps to produce better
starting torque.
Increase this setting when using a long motor cable or
when the motor is significantly smaller than the drive
capacity.
Decrease this setting when motor oscillation occurs. Set
the value so that the current at low speed does not exceeds
the drives rated current.
Open Loop Vector: Sets the torque compensation function
gain. Normally no change is required.

Torque Compensation Time
Constant
Sets the time constant for torque compensation at forward

Primary Delay Time 2
Sets the torque compensation time 2. When an ov fault
occurs with sudden load changes or at the and of an
acceleration, increase the setting.
Note: Adjustment is not normally required. If adjusted
then AFR time 2 (n2-03) should be adjusted too.
