Cycle parameters
U Center in 1st axis Q273 (absolute): Center of the hole
in the reference axis of the working plane. Input range
–99999.9999 to 99999.9999
U Center in 2nd axis Q274 (absolute value): Center of
the hole in the minor axis of the working plane. Input
range –99999.9999 to 99999.9999
U Nominal diameter Q262: Enter the diameter of the
hole. Input range 0 to 99999.9999
U Starting angle Q325 (absolute): Angle between the
reference axis of the working plane and the first touch
point. Input range –360.0000 to 360.0000
U Stepping angle Q247 (incremental): Angle
between two measuring points. The algebraic sign
of the stepping angle determines the direction of
rotation (negative = clockwise). If you wish to
probe a circular arc instead of a complete circle,
then program the stepping angle to be less than
90°. Input range: -120.0000 to 120.0000
