Cubical interpolation (o3925.1=-3)
With the aid of the last position received, and the three previous values, the poly-
nomal coefficients of the polynomal
Y(t) = a * t^3 + b * t^2 + c* are determined. The speed within a bus cycle can chan-
ge quadratically, i.e. the acceleration is a first order function.
 Advantages: consistent course of speed and acceleration
 Disadvantages: This method may lead to overshoot in the interpolated position..
The Interpolation method does not support a reset value range.
