Soft-Start Characteristics (n023)

To prevent shock during machine starting and/or stopping, accel/decel can be performed in S-curve pattern.
Note: S-curve characteristic time is the time from accel/decel rate 0 to a regular accel/decel rate determined by the set
accel/decel time.
The following time chart shows switching from FWD/REV at deceleration to stop.
