Assignment of geometry axes to channel axes
A distinction has to be made, whetherTRACYL is active or not:
● TRACYL not active
● TRACYL active
Entry of channel axes
Those axes, which do not belong to the Cartesian coordinate system, are entered.

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.

MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[1] = 2
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[2] = 3
The Y axis becomes an axis in the direction of the cylinder co-ordinate system.
