Note
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)

Restrictions
● It is not possible to switch the geometry axes over during:
● If the geometry axis and the channel axis have the same name, it is not possible to
● None of the axes involved in the changeover may be involved in an action that can go
● Geometry axes can only be replaced using the command GEOAX if they were already
● An alarm is output if an attempt is made to replace an axis with GEOAX while executing
