Which channel axis uses which machine axis (explicite) and how many channel axes are
present in the channel (implicite) is detemined through the following machine date:
MD20070: AXCONF_MACHAX_USED[n] (machine axis number valid in channel)
The machine axis number m to be entered in the machine data (with m=1,2,3...) is referred to
the appropriate machine axis m.
Which channel axis uses which machine axis (explicitly) and how many channel axes can be
implicitly available in a channel is defined by the following machine data:
MD20050: AXCONF_GEOAX_ASSIGN_TAB[n] (assignment geometry axis - channel axis) (n
= 0...2)
The channel axis number k to be entered in the machine data (k=1,2,3...) is referred to the
entry with the index n (n=(k-1)=0,1,2...) in the list of the channel axes MD20070:
AXCONFIG_MACHAX_USED[n] (see Point 3).
