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.
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 part program.
