Cycle parameters
U
Center in 1st axis
Q273 (absolute): Center of the
stud in the reference axis of the working plane. Input
range -99999.9999 to 99999.9999
U
Center in 2nd axis
Q274 (absolute): Center of the
stud in the minor axis of the working plane. Input
range -99999.9999 to 99999.9999
U
Nominal diameter
Q262: Enter the diameter of the
stud. 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
