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
