5.5 (F) Setting of acceleration/deceleration time and
acceleration/deceleration pattern
5.5.1 Setting the acceleration and deceleration time
The following parameters are used to set motor acceleration/deceleration time.
Set a larger value for a slower acceleration/deceleration, and a smaller value for a faster acceleration/deceleration.
For the acceleration time at automatic restart after instantaneous power failure, refer to Pr.611 Acceleration time at a restart
(page 448).
