Datum number in table Q305: Enter the number in
the datum/preset table in which the TNC is to save
the coordinates of the stud center. If Q303=1: If
you enter Q305=0, the TNC automatically sets the
display so that the new datum is on the stud center.
If Q303=0: If you enter Q305=0, the TNC writes to
line 0 of the datum table. Input range 0 to 99999
New datum for reference axis Q331 (absolute):
Coordinate in the reference axis at which the TNC
should set the stud center. Default setting = 0 input
range -99999.9999 to 99999.9999
New datum for minor axis Q332 (absolute):
Coordinate in the minor axis at which the TNC
should set the stud center. Default setting = 0 input
range -99999.9999 to 99999.9999
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 "Characteristics common
to all touch probe cycles for datum setting",
page 326)

: Write the measured datum into the active datum

table. The reference system is the active workpiece
coordinate system

: Write the measured datum into 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:

: Do not set the datum in the touch probe axis

: Set the 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 datum is
to be set in the touch probe axis. Only effective if
Q381 = 1st input range -99999.9999 to 99999.9999
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 datum is to be
set in the touch probe axis. Only effective if Q381 =
1. Input range -99999.9999 to 99999.9999
