Axis configuration
Assignment of geometry, special and machine axes to channel axes:
● MD10000 $MN_AXCONF_MACHAX_NAME_TAB
● MD20050 $MC_AXCONF_GEOAX_ASIGN_TAB
● MD20060 $MC_AXCONF_GEOAX_NAME_TAB
● MD20070 $MC_AXCONF_MACHAX_USED
● MD20080 $MC_AXCONF_CHANAX_NAME_TAB
● MD35000 $MA_SPIND_ASSIGN_TO_MACHAX
Reset behavior
Reset behavior of changed geometry axis assignments:
● MD20110 $MC_RESET_MODE_MASK, bit 12
● MD20118 $MC_GEOAX_CHANGE_RESET
NC start behavior
● MD20112 $MC_START_MODE_MASK, bit 12
Notification to the PLC user program
Parameterization option of the M command which is output on the NC/PLC interface when the
geometry axes are changed.
● MD22532 $MC_GEOAX_CHANGE_M_CODE
Supplementary conditions
No geometry axis changeover
● If one of the following functions is active, a geometry axis changeover is not possible:
– Transformation
– Spline interpolation
– Tool radius compensation
– Tool fine offset
● The geometry axis and another channel axis have the same name.
● One of the axes participating in the geometry axis changeover is involved in an action that
goes beyond block limits, e.g. block-wide positioning axis or following axis of an axis
coupling.
Rotary axes
Rotary axes cannot be programmed as geometry axes.
