Parameterization of the geometry axes

Standard setting
Machines for high-speed laser cutting normally have two geometry axes that are configured in
the following two machine data:
MD20050_$MC_AXCONF_GEOAX_ASSIGN_TAB[0]
MD20050_$MC_AXCONF_GEOAX_ASSIGN_TAB[1]
The calculation of the switching instants is derived from these two geometry axes.
Note
The configured axis selection for calculating the switching instants can be changed by
redefining the first and second geometry axes in the part program with the help of program
instructions GEOAX(1,
Important:
For the function change to be considered correctly, it should occur before the interpretation
of the CC_FASTON command.
Changing the default setting
For a deviating machine configuration (e.g. definition of a third geometry axis), the default
setting can be adjusted via the following machine data:
MD60948 $MN_CC_ACTIVE_IN_CHAN_HSCL[1]
Value
$MN_CC_ACTIVE_IN_CHAN_HSCL[1]='H3'
$MN_CC_ACTIVE_IN_CHAN_HSCL[1]='H7'
Any change is effective only after the next NCK booting.
