 Center in 1st axis Q273 (absolute value): Center of
the stud in the reference axis of the working plane.
 Center in 2nd axis Q274 (absolute value): Center of
the stud in the minor axis of the working plane.
 First side length Q282: stud length, parallel to the
reference axis of the working plane
 Second side length Q283: stud length, parallel to the
secondary axis of the working plane
 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.
 Setup clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140.
 Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between tool
and workpiece (fixtures) can occur.
 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
 Max. size limit 1st side length Q284: Maximum
permissible length of the stud.
 Min. size limit 1st side length Q285: Minimum
permissible length of the stud.
 Max. size limit 2nd side length Q286: Maximum
permissible width of the stud.
 Min. size limit 2nd side length Q287: Minimum
permissible width of the stud.
 Tolerance value for center 1st axis Q279:
Permissible position deviation in the reference axis of
the working plane.
 Tolerance value for center 2nd axis Q280:
Permissible position deviation in the minor axis of the
working plane.
