Axis data and signals

Introduction
Axis data and signals for a link axis are produced on the home NCU of the link axis. The
NCU that has caused the movement of a link axis is provided with axis data and signals from
the system:

Implicitly active link communication
During interpolation, data are made available for axes which are physically subordinate to a
non-local servo (identifiable from entries in machine data:
MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB or axis container),
via the link communication in the same manner as they are provided for local axes from the
logical viewpoint of part programs. The procedure remains concealed from the applications.
