* 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.
* 1. Varies by Duty Rating
Setting Acceleration and Deceleration Time Units
Set the acceleration/deceleration time units using C1-10. Parameter C1-10 is set to 1 at the factory.
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.
