AXCONF_GEOAX_ASSIGN_TAB
Assignment of geometry axis to channel axis
min. input limit: 0
The channel axis to which the geometry axis is assigned is specified in this MD. The
assignment for all the geometry axes is to be done channel-specifically. If no assignment is
defined for a geometry axis, then this geometry axis does not exist and cannot be
programmed (with the names defined in AXCONF_GEOAX_NAME_TAB).
E.g.: Turning machine without transformation:
$MC_AXCONF_GEOAX_ASSIGN_TAB[ 0 ] = 1 ; 1. Geo axis = 1st channel axis
$MC_AXCONF_GEOAX_ASSIGN_TAB[ 1 ] = 0 ; 2. Geo axis not defined
$MC_AXCONF_GEOAX_ASSIGN_TAB[ 2 ] = 2 ; 3. Geo axis = 2nd channel axis
The assignment defined here is valid if no transformation is active. In case of active
transformation n, the transformation-specific assignment table
TRAFO_GEOAX_ASSIGN_TAB_n is active.
AXCONF_GEOAX_NAME_TAB
Geometry axis name in channel
min. input limit: -
The names of the geometry axes for the channel are input separately in this MD. Geometry
axes can be programmed in the part program with the names specified here.
AXCONF_MACHAX_USED
Machine axis number valid in channel
min. input limit: 0
The machine axis to which the channel axis/special axis is assigned is input in this MD. The
assignment for all the channel axes is to be done channel-specifically. A machine axis that is
not assigned to any channel is not active, i.e. the axis control is not processed, the axis is
not displayed on the screen and it cannot be programmed in any channel.
