Path interpolator and axis interpolator

Path interpolator
Every channel has a path interpolator for a wide range of interpolation modes such as linear
interpolation (G1), circular interpolation (G2/G3), spline interpolation etc.
Axis interpolator
Each channel has axis interpolators in addition to path interpolators. The maximum number
corresponds to the maximum number of existing channel axes.
If a positioning axis is programmed, an axis interpolator starts in the control with straight line
interpolation G1. This axis interpolator runs independently of the path interpolator until the
programmed end position of the positioning axis has been reached.
There is no time relationship between the path interpolator and the axis interpolator, nor
between the axis interpolators.
Path control mode (G64) is not possible with positioning axes.
The programmed end position of a positioning axis has been reached when the end-of-motion
criterion FINEA, COARSA or IPOENDA is fulfilled.
