 Starting point in 1st axis Q328 (absolute): Starting
point for probing in the reference axis of the working
plane.
 Starting point in 2nd axis Q329 (absolute): Starting
point for probing in the minor axis of the working
plane.
 Offset for 2nd measurement Q310 (incremental):
Distance by which the touch probe is displaced
before the second measurement. If you enter 0, the
TNC does not displace the touch probe.
 Measuring axis Q272: Axis in the working plane in
which the measurement is to be made:
1: Reference axis = measuring axis
2: Minor axis = measuring axis
 Measuring height in the touch probe axis Q261
(absolute): Coordinate of the ball tip center (= touch
point) in the touch probe axis in which the
measurement is to be made.
 Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between tool
and workpiece (fixtures) can occur.
 Nominal length Q311: Nominal value of the length to
be measured.
 Maximum dimension Q288: Maximum permissible
length.
 Minimum dimension Q289: Minimum permissible
length.
 Measuring log Q281: Definition of whether the TNC is
to create a measuring log:
0: No measuring log
1: Generate measuring log: with the standard setting
the TNC saves the log file TCHPR425.TXT in the
directory in which your measuring program is also
stored.
2: Interrupt the program run and display the
measuring log on the screen. Resume program run
with NC Start.
 PGM stop if tolerance error Q309: Definition of
whether in the event of a violation of tolerance limits
the TNC is to interrupt the program run and output an
error message:
0: Do not interrupt program run, no error message
1: Interrupt program run, output an error message
 Tool number for monitoring Q330: Definition of
whether the TNC is to monitor the tool (see “Tool
monitoring” on page 112):
0: Monitoring not active
>0: Tool number in the tool table TOOL.T
