U

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

U

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

U

Axis for compensation motion Q312: assignment of

the rotary axis in which the TNC is to compensate the
measured misalignment:
4: Compensate misalignment with rotary axis A
5: Compensate misalignment with rotary axis B
6: Compensate misalignment with rotary axis C

U

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

U

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

U

Measured value transfer (0, 1) Q303: Specify if the

determined basic rotation is to be saved in the datum
table or in the preset table:
0: Write the measured basic rotation as a datum shift
in the active datum table. The reference system is the
active workpiece coordinate system.
1: Write the measured basic rotation into the preset
table. The reference system is the machine
coordinate system (REF system).

U

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
