Description
C2: S-Curve Characteristics
Use C2 parameters to configure S-curve operation.
The S-curve can be controlled in the four points shown below.

time
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.
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.
Disabled when Simple V/f Control with PG (H6-01 = 3) is used.
Sets the slip compensation upper limit. Set as a percentage of motor rated slip
(E2-02). Disabled when Simple V/f Control with PG (H6-01 = 3) is used.
Selects slip compensation during regenerative operation.
0: Disabled
1: Enabled
Using the Slip Compensation function during regeneration may require a
braking option to handle momentary increasing regenerative energy.
Selects if the motor magnetic flux is reduced during output voltage saturation.
0: Disabled
1: Enabled
C4: Torque Compensation
Use C4 parameters to configure Torque Compensation function.
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.
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.
Sets torque compensation at forward start as a percentage of motor torque.
Sets torque compensation at reverse start as a percentage of motor torque.
start (C4-03 and C4-04). The filter is disabled if the time is set to 4 ms or less.
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 with Simple PG (H6-01 = 3).
Sets the proportional gain of the speed control loop (ASR).
Sets the integral time of the speed control loop (ASR).
Sets the speed control gain 2 of the speed control loop (ASR).
Sets the integral time 2 of the speed control loop (ASR).
Sets the upper limit for the speed control loop (ASR) as a percentage of the
maximum output frequency (E1-04).
C6: Carrier Frequency
Use C6 parameters to configure the carrier frequency drive settings.
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.
Selects the carrier frequency
