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 64).
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
8
Probe TS axis: Coord. 1. st axis
Q382 (absolute):
Coordinate of the probe point in the reference axis of
the working plane at which point the datum is to be
set in the touch probe axis. Only effective if Q381 = 1.
8
Probe TS axis: Coord. 2. nd axis
Q383 (absolute):
Coordinate of the probe point in the reference axis of
the working plane at which point the datum is to be
set in the touch probe axis. Only effective if Q381 = 1.
8
Probe TS axis: Coord. 3. rd axis
Q384 (absolute):
Coordinate of the probe point in the reference axis of
the working plane at which point the datum is to be
set in the touch probe axis. Only effective if Q381 = 1.
8
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
