MD20152 $MC_GCODE_RESET_MODE
Each G code group controlled in MD20150 $MC_GCODE_RESET_VALUES[i] can be selectively controlled with
MD20152 $MC_GCODE_RESET_MODE[i].
MD20152 $MC_GCODE_RESET_MODE[i]
(i = G code group -1)
MD20150 $MC_GCODE_RESET_VALUES[i]
Part program start
The initial setting of the control system at part program start, e.g. G codes (especially active plane and active
settable zero offset), active tool length compensation, transformation, and axis coupling, is determined using
machine data:
MD20112 $MC_START_MODE_MASK (definition of the basic setting of the control after part program start)
Bit assignment, see:
References:
Detailed machine-data description
Application
If a bit is set in MD20112 $MC_START_MODE_MASK, the reset action of the relevant function can be delayed
until the start of the parts program.
Note
In MD20110 bits set to 1 cause settings to be retained,
in MD20112 bits set to 0 cause settings to be retained.
Significance of the machine data
The channel­specific machine data in the table "Selection of RESET and power-up response" has the following
significance:
