 Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between touch
probe and workpiece (fixtures) can occur. Input range
-99999.9999 to 99999.9999; alternatively PREDEF
 Traversing to clearance height Q301: Definition of
how the touch probe is to move between the
measuring points:
0: Move at measuring height between measuring
points
1: Move at clearance height between measuring
points
 Axis for compensation motion Q312: Assignment of
the rotary axis in which the TNC is to compensate the
measured misalignment.
0: Automatic mode – the TNC uses the active
kinematics to determine the rotary axis to be aligned.
In automatic mode the first rotary table axis (as
viewed from the workpiece) is used as compensation
axis. Recommended setting.
4: Compensate misalignment with rotary axis A
5: Compensate misalignment with rotary axis B
6: Compensate misalignment with rotary axis C
 Set to zero after alignment Q337: Definition of
whether the TNC should set the display of the aligned
rotary axis to zero:
0: Do not reset the display of the rotary axis to 0 after
alignment
1: Reset the display of the rotary axis to 0 after
alignment
 Number in table Q305: Enter the number in the
preset table/datum table in which the TNC is to set
the rotary axis to zero. Only effective if Q337 is set to
1. Input range 0 to 99999
 Measured-value transfer (0, 1) Q303: Specify
whether the determined angle is to be saved in the
datum table or in the preset table:
0: Write the measured angle as a datum shift in the
active datum table. The reference system is the
active workpiece coordinate system.
1: Write the measured angle in the preset table. The
reference system is the machine coordinate system
(REF system).
 Reference angle? (0=ref. axis) Q380: Angle with
which the TNC is to align the probed straight line.
Only effective if rotary axis = automatic mode is
selected, or rotary axis = C is selected (Q312 = 0 or
6). Input range -360.000 to 360.000
