Machine data
MD20144 $MC_TRAFO_MODE_MASK
MD20150 $MC_GCODE_RESET_VALUES
MD20152 $MC_GCODE_RESET_MODE
MD21330 $MC_COUPLE_RESET_MODE_1
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB
MD20118 $MC_GEOAX_CHANGE_RESET
Example
1. Activate RESET setting on RESET:
MD20110 = 'H01' (bit 0)
MD20112 = '0'
2. Transformation remains active on RESET/parts program start:
MD20110 = 'H81' (bit 0 + bit 7)
MD20112 = '0'
3. Tool length compensation remains active on RESET/part program start:
MD20110 = 'H41' (bit 0 + bit 6)
MD20112 = '0'
4. Active level (bit 4) and settable frame (bit 5) remain active after RESET and are reset on parts program start:
MD20110 = 'H31' (bit 4 + bit 5)
MD20112 = '30'
Note
For bit 5 and bit 6:
If MD20110/MD20112 are parameterized so that tool length compensation or a frame is
active on a parts program start/MDI start, the first programming of the axes must use
absolute measurements (because of the offsetting process) .
Exception: With MD42442/MD42440 the offsetting process for G91 is suppressed.

Meaning
Selection of the kinematic transformation function
Setting bit 1 causes the last active transformation to be
retained on POWER ON.
Initial setting of the G groups
Reset behavior of G groups
G code initial state on RESET
MD20152 specifies for each entry in MD20150
$MC_GCODE_RESET_VALUES whether the setting in
accordance with MD20150 $MC_GCODE_RESET_VALUES
is adopted again (MD20152=0) or the current setting is
retained (MD20152=1) on reset/part program end.
Coupling cancellation response
Cancelation of an axis coupling
Assignment of geometry axis to channel axis
Acts upon bit 12 in MD20110/20112
Allow automatic geometry axis change
Acts upon bit 12 in MD20110/20112
