378  Touch Probe Cycles: Automatic Datum Setting
15.10 DATUM CIRCLE CENTER (Cycle 416, DIN/ISO: G416)
Please note while programming:
Cycle parameters
U Center in 1st axis Q273 (absolute): Bolt hole circle 
center (nominal value) in the reference axis of the 
working plane. Input range -99999.9999 to 
99999.9999
U Center in 2nd axis Q274 (absolute): Bolt hole circle 
center (nominal value) in the minor axis of the working 
plane. Input range -99999.9999 to 99999.9999
U Nominal diameter Q262: Enter the approximate bolt 
hole circle diameter. The smaller the hole diameter, 
the more exact the nominal diameter must be. Input 
range -0 to 99999.9999
U Angle of 1st hole Q291 (absolute): Polar coordinate 
angle of the first hole center in the working plane. 
Input range -360.0000 to 360.0000
U Angle of 2nd hole Q292 (absolute): Polar coordinate 
angle of the second hole center in the working plane. 
Input range -360.0000 to 360.0000
U Angle of 3rd hole Q293 (absolute): Polar coordinate 
angle of the third hole center in the working plane. 
Input range -360.0000 to 360.0000
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 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
Before a cycle definition you must have programmed a 
tool call to define the touch probe axis.
