* The setting range for accel/decel time will differ depending on C1-10 (Accel/Decel Time Units). If C1-10 is set to "0", then the setting range will change to
0.00sec to 600.00sec.
** Varies by Duty Rating.
„ S-curve Acceleration/Deceleration: C2
User parameters for S-curve characteristics are shown in the following table.
C1-11
Accel/decel
Switch
Frequency Sets the frequency for
automatic switching of
accel / decel times.
Fout < C1-11: Accel/Decel
Time 4
Fout ≥ C1-11: Accel/Decel
Time 1
Multi-function inputs
"Multi-Acc/Dec 1" and
"Multi-Acc/Dec 2" have
priority over C1-11.
Note: With Multi-Function
Input, Accel/Decel
Time 1 and 2 will take
precedence.

S-curve
Characteristic
at Accel
Start
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.
Note:With this setting, accel/decel times
will be exactly half of the start and
finish times of the
S-curve characteristic time.
