FUNCTION_BLOCK SMC_CAMBounds_Pos
In opposite to SMC_CAMBounds this function block calculates only the maximum and minimum position 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.
