Section 5-3
Output Pattern
The output pattern for S-curve acceleration/deceleration is shown below.
Example for PLS2(887)
The same type of S-curve acceleration/deceleration can be used for
ACC(888) as well.
Note
The curve for S-curve acceleration/deceleration is formed by applying a cubic
equation to the straight line of the set acceleration/deceleration rates (a cubic
polynomial approximation). The curve’s parameters cannot be changed.
The maximum acceleration will be 1.5 times that of trapezoidal acceleration/
deceleration for the same acceleration/deceleration rate.
