Description
Sets the frequency for automatic acceleration/deceleration
switching.
Below set frequency: Accel/Decel Time 4
Above set frequency: Accel/Decel Time 1
The multi-function input "Accel/Decel Time 1" or "Accel/
Decel Time 2" take priority.
Sets the base frequency used to calculate acceleration and
deceleration times.
When set to 0.0 Hz, the drive calculates the time required
to accelerate from 0 Hz to E1-04, and decelerate from E1-04
down to 0 Hz (conventional setting).
When set to any other value above 0.0 Hz, the drive
calculates the time required to accelerate from 0 Hz to
C1-14, and to decelerate from C1-14 down to 0 Hz.
C2: S-Curve Characteristics
Use C2 parameters to configure S-curve operation.
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.
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
Sets the maximum percentage of output voltage reduction
when C3-05 is enabled.
C4: Torque Compensation
Use C4 parameters to configure Torque Compensation function.
