MD20118 $MC_GEOAX_CHANGE_RESET
Program start
Analogously to the Reset response, the behavior during program start is based on the setting in the machine
data:
MD20112 $MC_START_MODE_MASK (definition of initial control system settings with NC-START)
Approaching a reference point
When the "Reference point approach" mode is selected, the geometry axis configuration defined by the machine
data is automatically set.
M code
A changeover of the geometry axis with GEOAX( ) can be communicated to the PLC through the output of an M
code:
MD22532 $MC_GEOAX_CHANGE_M_CODE (M-Code during tool holder change)
Value Significance
0 The current configuration of the geometry axes remains unchanged on reset and program
start. With this setting, the response is identical to older software versions without geometry
axis replacement.
1 The configuration of the geometry axis remains unchanged during reset or parts program
end as a function of machine data MD20110$MC_RESET_MODE_MASK and during parts
program start as a function of machine data MD20112$MC_START_MODE_MASK
(definition of initial control system settings with NC START) or brought to the initial status
defined in the machine data MD20050$MC_AXCONF_GEOAX_ASSIGN_TAB (assignment
of geometry axis to channel axis).
Bit Value Significance
12 0 A modified geometry axis assignment remains active on part-program start.
1 A modified geometry axis assignment is cleared on part-program start.
Note
If this machine data is set to one of the values 0 to 6, 17, 30, then no M code is output.
