the working plane. Input range -99999.9999 to
99999.9999
Q269 1st hole: center in 2nd axis? (absolute):
Center of the first hole in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Q270 2nd hole: center in 1st axis? (absolute):
Center of the second hole in the reference axis
of the working plane. Input range -99999.9999 to
99999.9999
Q271 2nd hole: center in 2nd axis? (absolute):
Center of the second hole in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Q316 3rd hole: Center in 1st axis? (absolute):
Center of the third hole in the reference axis of
the working plane. Input range -99999.9999 to
99999.9999
Q317 3rd hole: Center in 2nd axis? (absolute):
Center of the third hole in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Q318 4th hole: Center in 1st axis? (absolute):
Center of the fourth hole in the reference axis of
the working plane. Input range -99999.9999 to
99999.9999
Q319 4th hole: Center in 2nd axis? (absolute):
Center of the fourth hole in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Q261 Measuring height in probe axis? (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
Q260 Clearance height? (absolute): coordinate in
the touch probe axis at which no collision between
tool and workpiece (fixtures) can occur. Input
range -99999.9999 to 99999.9999
Q305 Number in table?: Specify the row number
of the preset table/datum table to which the TNC
saves the coordinates of the intersection of the
connecting lines; input range 0 to 9999.
Q303 = 1: The TNC writes to the preset table.
If the active preset is modified this change
immediately becomes effective. Otherwise an
entry is made in the specific row of the preset
table without automatic activation
Q303 = 0: The TNC writes to the datum table. The
datum is not automatically activated
