Assignment of names to geometry axes
According to the axis configuration overview shown above, the geometry axes involved in
the TRANSMIT operation must be defined with:
MD20060 $MC_AXCONF_GEOAX_NAME_TAB[0]="X"
MD20060 $MC_AXCONF_GEOAX_NAME_TAB[1]="Y"
MD20060 $MC_AXCONF_GEOAX_NAME_TAB[2]="Z"
(The choice of names in the above figure is in accordance with defaults).
Assignment of geometry axes to channel axes
A distinction has to be made, whetherTRANSMIT is active or not:
● TRANSMIT not active
● TRANSMIT active
Entry of channel axes
Those axes, which do not belong to the Cartesian coordinate system, are entered.
MD20080 $MC_AXCONF_CHANAX_NAME_TAB[0]="XC"
MD20080 $MC_AXCONF_CHANAX_NAME_TAB[1]="ZC"
MD20080 $MC_AXCONF_CHANAX_NAME_TAB[2]="CC"
MD20080 $MC_AXCONF_CHANAX_NAME_TAB[3]="ASC"
Assignment of channel axes to machine axes
With the cd of the channel axes as a reference, the machine axis number to which the
channel axes have been assigned, is transferred to the control system.
MD20070 $MC_AXCONF_MACHAX_USED[0]=2
MD20070 $MC_AXCONF_MACHAX_USED[1]=3
MD20070 $MC_AXCONF_MACHAX_USED[2]=1
MD20070 $MC_AXCONF_MACHAX_USED[3]=4
MD20070 $MC_AXCONF_MACHAX_USED[4]=0
(entries corresponding to the figure above)

One y-axis is not available.
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[0]=1
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB_TAB[1]=0
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB_TAB[2]=2
The Y-axis can be addressed by the parts program.
MD24120 $MC_TRAFO_GEOAX_ASSIGN_TAB_1[0]=1
MD24120 $MC_TRAFO_GEOAX_ASSIGN_TAB_1[1]=3
MD24120 $MC_TRAFO_GEOAX_ASSIGN_TAB_1[2]=2
The Y-axis becomes the third entry of the channel axes.
