Cycle parameters
U 1st meas. point 1st axis Q263 (absolute):
Coordinate of the first touch point in the reference
axis of the working plane. Input range: -99999.9999 to
99999.9999
U 1st meas. point 2nd axis Q264 (absolute):
Coordinate of the first touch point in the minor axis of
the working plane. Input range: -99999.9999 to
99999.9999
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 MP6140. Input range 0 to 99999.9999,
alternatively PREDEF
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, alternatively PREDEF
U Measuring axis (1...3: 1=reference axis) Q272:
Axis in which the measurement is to be made:
1: Reference axis = measuring axis
2: Minor axis = measuring axis
3: Touch probe axis = measuring axis
