A key-initiated Reset, mode change or M2/M30 does not deselect
transformation (TRANSMIT).
Active: RESET
Note:
For as from SW 6, transformation is always deselected on warm restart
irrespective of the setting of MD bit "No transformation deselection on
RESET".
Transformation is always deselected in 'Reference point approach'
mode.
Causes the F value to be programmed in m/min.
This MD affects all metric input systems. The maximum axial speeds
specified in the machine data are not affected (input unit is still 'units').
Programming of F10 Speed 10 m/min
The feedrate display depends on the status of this bit. The feedrate for
F external and dry run is not converted into m/min. This MD has no
effect on "inch" systems, i.e. the feedrate is always defined in
inches/min.
Active: In the next block
