3.5.4 S-pattern acceleration/deceleration curve (Pr. 29, Pr. 140 to Pr. 143, Pr. 380 to
Pr. 383 )
When you have changed the preset speed during start, acceleration, deceleration, stop, or operation, you can
change the running speed by acceleration/deceleration to make adjustment to reach the preset speed. Set
the acceleration/deceleration pattern in Pr. 29 "acceleration/deceleration pattern".
