Machine manufacturer
Your machine manufacturer will instruct you how to select axes if you
intend to enter more than nine.

The sequence in which axes must be referenced can be defined by
the machine-tool manufacturer.
The NC cannot be started in automatic mode until all axes with a
defined reference point (see machine data MD) have actually reached
this point.
