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.
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.
