End of definition. The curve table is generated in its
internal representation as a polynomial of up to the 5th
order. The calculation of the curve definition with the
specified intermediate points is dependent on the modally
selected interpolation type (circular, linear, spline
interpolation). The part program state before starting
the definition is restored.
Example 3: Definition of a periodic curve table
Definition of a periodic curve table with number 2, master value range 0 to 360, following
axis motion from 0 to 45 and back to 0:
