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
Primary Delay Time
Sets the torque compensation filter time.
Increase this setting when motor oscillation occurs.
Reduce the setting if there is not enough response from the
motor.

Torque Compensation Time
Constant
Sets the time constant for torque compensation at forward
start and reverse start (C4-03 and C4-04). The filter is
disabled if the time is set to 4 ms or less.

Torque Compensation
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.

C5: Speed Control (ASR)
Use C5 parameters to configure the Automatic Speed Regulator (ASR).
C5 parameters are available only when using V/f Control with Simple PG Feedback (H6-01 = 3).

C6: Carrier Frequency
Use C6 parameters to configure the carrier frequency drive settings.
C6-01 Drive Duty Selection
Selects the load rating for the drive.
0: Heavy Duty (HD) for constant torque applications.
1: Normal Duty (ND) for variable torque applications.
This setting affects the Rated output current and overload
tolerance of the drive.
