Axis configuration
The machine data below are used to assign the geometry axes, special axes, channel axes and machine axes as
well as the names of the individual axis types:
MD20050 $MC_AXCONF_GEOAX_ASIGN_TAB (assignment of geometry axis to channel axis)
MD20060 $MC_AXCONF_GEOAX_NAME_TAB (name of the geometry axis in the channel)
MD20070 $MC_AXCONF_MACHAX_USED (machine axis number valid in channel)
MD20080 $MC_AXCONF_CHANAX_NAME_TAB (name of the channel axis in the channel)
MD10000 $MN_AXCONF_MACHAX_NAME_TAB (machine axis name)
MD35000 $MA_SPIND_ASSIGN_TO_MACHAX (assignment of spindle to machine axis)
Replaceable geometry axes
The "Replaceable geometry axes" function allows the geometry axes in a grouping to be replaced by other
channel axes.
Axes that are initially configured as synchronous special axes in a channel can replace any selected geometry
axis in response to a program command.
Link axis
Link axes are axes, which are physically connected to another NCU and whose position is controlled from this
NCU. Link axes can be assigned dynamically to channels of another NCU. Link axes are not local axes from the
perspective of a particular NCU.
The axis container concept is used for the dynamic modification of the assignment to an NCU. Axis replacement
with
GET
and
RELEASE
from the part program is not available for link axes across NCU boundaries.
The link axes are described in

Axis container
An axis container is a circular buffer data structure, in which local axes and/or link axes are assigned to channels.
The entries in the circular buffer can be shifted cyclically.
In addition to the direct reference to local axes or link axes, the link axis configuration in the logical machine axis
image also allows references to axis containers.
This type of reference consists of:
• Axis container number
• A slot (circular buffer location within the corresponding container)
The entry in a circular buffer location contains:
• A local axis
