For example, for a turning machine with X and Z axes, main spindle (C1), tool
spindle (WZ), and counter–spindle (C2) you must configure the following ma-
chine data:
2008020080 $MC_AXCONF_CHANAX_NAME_TAB[0]="XC"
Channel axis XC
20080 $MC_AXCONF_CHANAX_NAME_TAB[1]="ZC"
Channel axis ZC
20080 $MC_AXCONF_CHANAX_NAME_TAB[2]="C1"
Channel axis C1
20080 $MC_AXCONF_CHANAX_NAME_TAB[3]="WZ"
Channel axis WZ
20080 $MC_AXCONF_CHANAX_NAME_TAB[4]="C2"
Channel axis C2
General settings for transformations:
10602 $MN_FRAME_GEOAX_CHANGE_MODE=1

tween geometry axes
24040 $MC_FRAME_ADAPT_MODE=H7
Adaptation of active frames
28082 $MC_MM_SYSTEM_FRAME_MASK, Bit 6 = 1
