S-curve is used to further soften the starting and
stopping ramp. The longer the S-curve time, the
softer the starting and stopping ramp.

Gain
Sets the slip compensation gain. Decides for what
amount the output frequency is boosted in order to
compensate the slip.
Note: Adjustment is not normally required.

Torque
Compensation
Gain
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 drive rated current.

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.
