; 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 intermediate point
Master value: 0...20, Following value: starting value...0
; 3rd intermediate point:
Master value: 20...100, Following value: 0 to 6
; 4th intermediate point:
Master value: 100...150, Following value: 6 to 6
; 5th intermediate point:
Master value: 150...180, Following value: 6 to 0
; 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.
