 New datum for reference axis Q331 (absolute):
Coordinate in the reference axis at which the TNC
should set the pocket center. Basic setting = 0
 New datum for minor axis Q332 (absolute):
Coordinate in the minor axis at which the TNC should
set the pocket center. Basic setting = 0
 Measured-value transfer (0, 1) Q303: Specify
whether the determined datum is to be saved in the
datum table or in the preset table:
-1: Do not use. Is entered by the TNC when old
programs are read in (see “Saving the calculated
datum” on page 69).
0: Write determined datum in the active datum table.
The reference system is the active workpiece
coordinate system.
1: Write determined datum in the preset table. The
reference system is the machine coordinate system
(REF system).
 Probe in TS axis Q381: Specify whether the TNC
should also set the datum in the touch probe axis:
0: Do not set datum in the touch probe axis
1: Set datum in the touch probe axis
 Probe TS axis: Coord. 1st axis Q382 (absolute):
Coordinate of the probe point in the reference axis of
the working plane at which point the reference point
is to be set in the touch probe axis. Only effective if
Q381 = 1.
 Probe TS axis: Coord. 2nd axis Q383 (absolute):
Coordinate of the probe point in the minor axis of the
working plane at which point the reference point is to
be set in the touch probe axis. Only effective if Q381
= 1.
 Probe TS axis: Coord. 3rd axis Q384 (absolute):
Coordinate of the probe point in the touch probe axis,
at which point the reference point is to be set in the
touch probe axis. Only effective if Q381 = 1.
 New datum for touch probe axis Q333 (absolute):
Coordinate in the touch probe axis at which the TNC
should set the datum. Basic setting = 0
 No. of measuring points (4/3) Q423: Specify
whether the TNC should measure the hole with 4 or
3 probing points:
4: Use 4 measuring points (standard setting)
3: Use 3 measuring points (standard setting)
Example: NC blocks
