Setting the Acceleration/Deceleration Time Chapter 5-6
S-shape Acceleration/Deceleration Characteristic (n20)
• Trapezoidal and S-shape acceleration and deceleration are available.
Using the S-shape characteristic function for acceleration and
deceleration can reduce shock to the machinery when stopping or
starting.
• Any one of three S-shape acceleration/deceleration times (0.2, 0.5, and
1.0 s) is selectable.
Set Values
Note When the S-shape acceleration/deceleration characteristic time is set,
the acceleration and deceleration times will be lengthened according to the
S-shape at the beginning and end of acceleration/deceleration.
