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
