9.2 Curve tables (CTAB)
Function
Curve tables can be used to program position and velocity relationships between two axes
(leading and following axis). Curve tables are defined in the part program.
Application
Curve tables replace mechanical cams. The curve table forms the basis for the axial master
value coupling by creating the functional relationship between the leading and the following
value: With appropriate programming, the control calculates a polynomial that corresponds
to the cam from the relative positions of the leading and following axes.
