U 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.
Input range –99999.9999 to 99999.9999
U Setup clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to SET_UP (touch probe table). Input range
0 to 99999.9999
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 Maximum limit of size for hole Q275: Maximum
permissible diameter for the hole (circular pocket).
Input range 0 to 99999.9999
U Minimum limit of size for hole Q276: Minimum
permissible diameter for the hole (circular pocket).
Input range 0 to 99999.9999
U Tolerance for center 1st axis Q279: Permissible
position deviation in the reference axis of the working
plane. Input range 0 to 99999.9999
U Tolerance for center 2nd axis Q280: Permissible
position deviation in the minor axis of the working
plane. Input range 0 to 99999.9999
