Description
C1: Acceleration and Deceleration Times
Use C1 parameters to configure motor acceleration and deceleration.
Sets the time to accelerate from 0 to maximum frequency.
Sets the time to decelerate from maximum frequency to
0.
Sets the time to accelerate from 0 to maximum frequency
when Accel/Decel times 2 are selected by a digital input.
Sets the time to decelerate from maximum frequency to 0
when Accel/Decel times 2 are selected by a digital input.
Sets the time to accelerate from 0 to maximum frequency
when Accel/Decel times 3 are selected by a digital input.
Sets the time to decelerate from maximum frequency to 0
when Accel/Decel times 3 are selected by a digital input.
Sets the time to accelerate from 0 to maximum frequency
when Accel/Decel times 4 are selected by a digital input.
Sets the time to decelerate from maximum frequency to 0
when Accel/Decel times 4 are selected by a digital input.
Sets the time to decelerate from maximum frequency to 0
for the multi-function input fast-stop function.
Note: This parameter is also used by selecting "Fast-Stop"
as a Stop Method when a fault is detected.
Sets the resolution of C1-01 to C1-09.
0: 0.01 s (0.00 to 600.00 s)
1: 0.1 s (0.0 to 6000.0 s)
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.
