H S-shape Acceleration/Deceleration Characteristic (n20)
• Trapezoidal and S-shape acceleration and deceleration are available. Using the S-shape characteris-
tic 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.

Value Description
0 No S-shape acceleration/deceleration characteristic (Trapezoidal acceleration/deceleration)
1 S-shape acceleration/deceleration characteristic time is 0.2 s
2 S-shape acceleration/deceleration characteristic time is 0.5 s
3 S-shape acceleration/deceleration characteristic time is 1.0 s
Note When the S-shape acceleration/deceleration characteristic time is set, the acceleration and de-
celeration times will be lengthened according to the S-shape at the beginning and end of accel-
eration/deceleration.
