Example
In the example below, it is assumed that there are 6 channel axes with channel axis names
XX, YY, ZZ, U, V, W and three geometry axes with names X, Y, Z. The basic setting is
defined in machine data such that the geometry axes are imaged on the first three channel
axes, i.e., on XX, YY and ZZ.

; The geometry axis assignment defined via the machine data
MD AXCONF_GEOAX_ASSIGN_TAB
is effective,
i.e., XX, YY and ZZ become geometry axes.
; All the axes in rapid traverse to position 0.
; Channel axis U becomes the first, V the second and W the third
geometry axis.
; Channel axis XX becomes the first, ZZ the third geometry axis.
The second geometry axis remains unchanged.
; Semicircle in the X, Y plane. Channel axes XX and V traverse.
; Channel axis W becomes the second geometry axis. The first
and third geometry axes remain unchanged.
; Full circle in the X, Y plane. Channel axes XX and W traverse.
; The geometry axis assignment defined via the machine data
MD AXCONF_GEOAX_ASSIGN_TAB
is effective,
i.e., XX, YY and ZZ become geometry axes.
; U, V and W become the first, second and third geometry axes.
; Channel axes U, V, W each traverse to position 10, XX
traverses to position 25.
; V is again removed from the geometry axis grouping. U and W
remain geometry axes. The second geometry axis is no longer
assigned.
; U, V and W become the first, second and third geometry axes,
i.e., U and W remain unchanged.
; V becomes the third geometry axis. This means that W, which
was previously the third geometry axis, is removed from the
geometry axis grouping. The second geometry axis is no longer
assigned.
