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
<1>
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.

The coefficient K depends on C6-03:
C6-03 ≥ 10.0 kHz: K = 3
10.0 kHz > C6-03 ≥ 5.0 kHz: K = 2
5.0 kHz > C6-03: K = 1
When C6-05 ≤ 6, C6-04 is disabled (makes the carrier frequency
C6-03 value).
