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.
