MD20152 $MC_GCODE_RESET_MODE
In SW 5 and higher, MD20152 $MC_GCODE_RESET_MODE replaces Bits 4 and 5 from
MD20110 $MC_RESET_MODE_MASK. In addition, the setting options are expanded:
Up to and including SW 4
the following applies to Bits 4 and 5 of MD20110 $MC_RESET_MODE_MASK:
Bit 4: Level control
Bit 5: Control of settable frames
Each G code group controlled in MD20150 $MC_GCODE_RESET_VALUES[i] can be
selectively controlled with the additional MD20152 $MC_GCODE_RESET_MODE[i].
MD20152 $MC_GCODE_RESET_MODE[i]
(i = G code group -1)
0 1
MD20150 $MC_GCODE_RESET_VALUES[i] The value stored in
MD20150 is active
The last active/
current value is active
Note
The previous setting option in machine data MD20110 $MC_RESET_MODE_MASK
is omitted!
The corresponding bits of this MD are tagged as reserved. Write operations involving these
bits are automatically redirected to the corresponding array elements of
MD20150 $MC_GCODE_RESET_MODE and Alarm 4502 is output.
When MD20110 $MC_RESET_MODE_MASK is read, the information from the relevant field
arrays of MD20150 $MC_GCODE_RESET_MASK are read again and written to MD20110
$MC_RESET_MODE_MASK.
The mode of functioning of MD20112 $MC_START_MODE_MASK remains the same as in
SW5.
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 according to the following table.
