(b) S-pattern acceleration/deceleration processing method
In this method, the motor burden is reduced during starting and stopping.
This is a method in which acceleration/deceleration is carried out gradually,
based on the acceleration time, deceleration time, speed limit value, and
" Pr.36 S-pattern proportion" (1 to 100%) set by the user.

Time
Fig. 12.44 S-pattern acceleration/deceleration processing method
When a speed change request is given during S-pattern
acceleration/deceleration processing, S-pattern acceleration/deceleration
processing begins at a speed change request start.
When speed change
request is not given
Speed change (acceleration)
Command speed before speed change
Speed change request
Speed change (deceleration)
