1) Measurement in the 3rd axis of the plane is also possible, provided this axis exists (_MA=3: if G18
is in the Y axis).
2) For measurement in the 3rd axis (in G18 in Y _SZO applies in this axis. _SZA still applies in the 1st
axis in the plane (Z axis in G18). Travel around is performed in the 1st axis of the plane (Z axis in
G18). Setting _CHBIT[19]=1 in block GUD6 enables the same setpoint and safety zone
parameterization to be used for measurement in the 3rd axis (measurement in the Y axis) with active
G18 as for measurement in the X axis (facing axis). The tool offset is then also in L1 if not specified
differently in _KNUM.

Data type Meaning
1 or 2 1: Inside measurement, 2-point measurement with safety zone
2: 2-point measurement, safety zone only for outside measurement
REAL Setpoint
2)
If measurement is made in the transverse axis and diameter
programming (DIAMON) is active, then _SETVAL is a diameter
dimension, otherwise a radius dimension around the workpiece zero.
1, 2, 3 Measuring axis
1)
REAL Protection zone at the workpiece in the abscissa2)
If the abscissa is a transverse axis and diameter programming
(DIAMON) is active, then _SZA is a diameter dimension, otherwise a
radius dimension around the workpiece zero.
REAL Protection zone at the workpiece in the ordinate2)
If the ordinate is a transverse axis and diameter programming
(DIAMON) is active, then _SZO is a diameter dimension, otherwise a
radius dimension around the workpiece zero.
0, > 0 0: Without automatic tool offset
>0: with automatic tool offset
(individual values: See Section 2.3, parameter _KNUM)
INTEGER, ≥0 Tool number for automatic tool offset
STRING[32] Tool name for automatic tool offset
(alternative to _TNUM with tool management active)
INTEGER, ≥0 DL number for additive and setup offset
STRING[32] Name of tool environment for automatic tool offset
