Cam Toolbox: Function Blocks
MotionWorks IEC61131-3 Toolboxes: 2013-09-13 78
CamBlend
This function block was designed for applications that require a one way cam profile, and the slave must be able
to engage or disengage smoothly from a moving master. It requires three separate cam tables with a portion of
equivalent slave data, so an on-the-fly changeover from one table to the next can occur. This function block
uses three Y_CamIn functions blocks and one Y_CamOut function block.
