RESET response of master spindle
Up to SW 6.3 the master spindle setting was reset to the configured value on M30/RESET.
Depending on the setting of Bit 0 of MD20110 $MC_RESET_MODE_MASK, there are two
cases:
Bit 0 = 0:
No Init blocks are generated. (default: the current settings are retained)
Bit 0 = 1:
Init blocks are generated. The settings activated by RESET become valid.
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].
