SMC_CAMBounds (FB)¶

FUNCTION_BLOCK SMC_CAMBounds

This function block calculates the minimum/maximum position and an estimate of the minimum/maximum 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.

Note: The minimum/maximum velocity and acceleration values are estimates of lower/upper bounds which do not necessarily have to be reached.
