C2: S-Curve Characteristics
Use C2 parameters to configure S-curve operation.
C2-01 S-Curve Characteristic at Accel Start
The S-curve can be controlled in the four points shown below.

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.

C3: Slip Compensation
Use C3 parameters to configure the slip compensation function.
C3-01 <22> Slip Compensation 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.

Adjusts the slip compensation function delay time.
Decrease the setting when the slip compensation response is too slow, increase
it when the speed is not stable.

Slip Compensation Selection during
Regeneration
Selects slip compensation during regenerative operation.

Using the Slip Compensation function during regeneration may require a
braking option to handle momentary increasing regenerative energy.

C4: Torque Compensation
Use C4 parameters to configure Torque Compensation function.
C4-01 <23> 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.

C4-05 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.
