"Multi-Acc/Dec 2" have
priority over C1-11.
Note: With Multi-Function
Input, Accel/Decel
Time 1 and 2 will take
precedence.
* 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.

the S-curve time, the softer the starting
S-curve
