C1-09 Fast-Stop Time
Sets the time to decelerate from maximum frequency to 0 for the
multi-function input fast-stop function.

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.

C3-02
Slip Compensation
Primary Delay
Time
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.

C4: Torque Compensation
Use C4 parameters to configure Torque Compensation function.
C4-01
<22>
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
Normal/Heavy
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.
