Axis names

Machine axes
Each machine axis, channel axis and geometry axis is assigned an individual name that clearly
identifies the axis. Machine axis names must be unambiguous for the entire NC. The name of
the machine axes are defined via the following machine date:
MD10000 $MN_AXCONF_MACHAX_NAME_TAB [n] (machine axis name)
The specified names and the associated index are used in the following cases:
● Accessing axis-specific machine data (loading, saving, displaying)
● Reference point approach from the parts program G74
● Measuring
● Test point traversing from the parts program G75
● Traversing the machine axis from the PLC
● Display of axis-specific alarms
● Display in the actual-value system (machine-related)
● DRF handwheel function
Channel axes
The name of the channel axes are defined via the following machine date:
MD20080 $MC_AXCONF_CHANAX_NAME_TAB[n] (name of the channel axis in the channel)
Channel axis names must be unambiguous for the entire channel.
Geometry axes
The names of the geometry axes must be absolutely unique throughout the channel, and are
defined using the following machine data:
