Built-in Outputs Section 6-2
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 ter-
tiary function to the straight line of the set acceleration/deceleration rates (a
tertiary polynomial approximation). The maximum acceleration will be 1.5
times that of trapezoidal acceleration/deceleration for the same acceleration/
deceleration rate.
Procedure Make the following settings in the PLC Setup.
Pulse Output 0 Speed Curve (CJ1M CPU Unit Ver. 2.0 Only)
Pulse Output 1 Speed Curve (CJ1M CPU Unit Ver. 2.0 Only)
