; Beginning of the definition of a ;non-periodic curve
table with number 3.
; 1st motion operation, defines the starting values and
1st intermediate point:
Master value: 0, Following value: 0
; 2nd interpolation point:
Master value: 0...20, Following value: starting value...0
; 3rd interpolation point:
Master value: 20...100, Following value: 0...6
; 4th interpolation point:
Master value: 100...150, Following value: 6...6
; 5th interpolation point:
Master value: 150...180, Following value: 6...0
; End of the 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, lin-
ear, spline interpolation). The part program state be-
fore starting the definition is restored.
