Principal functions curve tables (CTABDEF, CTABEND, CTABDEL)

Function
You can use curve tables to program position and velocity relationships between two axes.
Curve tables are defined in a parts program.
Example of substitution of mechanical cam:
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.
