 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. Recommendation: Use the
automatic mode 0:
0 : Automatic mode; the TNC automatically
determines the axis for the compensation movement
from the positions of the active rotary and probing
axes.
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 2999
 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 the rotary axis C is selected
(Q312=6). Input range -360.000 to 360.000
