FUNCTION_BLOCK SMC_CAMBounds
This function block calculates the maximum position, velocity and acceleration values of the slave being coupled in absolute mode to a master, which is moved according to a prescribed maximum velocity and acceleration/deceleration.
This module is especially helpful when a cam disc is created and modified in online mode and the observance of the maximum values have to be checked in advance.
