Special cases and further details
All path data are always entered as radii even if for a facing axis with active G code
"DIAMON". If the part of one of the involved axes cannot be traversed completely, the paths
of the other axes will also be reduced accordingly in the _MAXDIST return value so that the
resulting end point lies on the specified path.
It is permissible that no software limits, operating range limits or protection zones are defined
for one or more of the axes involved. All limits are only monitored if the axes involved are
referenced. Any involved rotary axes are monitored only if they are not modulo axes.
As in the normal traversing operation, the monitoring of the software limits and the operating
range limits depends on the active settings (interface signals for selecting the software limits
1 or software limits 2, GWALIMON/WALIMOF, setting data for the specific activation of the
operating range limits and for the specification whether or not the radius of the active tool is
to be considered for the monitoring of the operating range limits).

Comments
[1] (= Y)
4.594
Protection zone N3 violated.
11.429
No protection zone monitoring, working
area limitation violated.
17.143
Now only monitoring of the software
limits active.
0.000
Start point violates protection zone C4.
–.000
Pre-activated protection zone C4 not
monitored. Defined path can be
traversed completely.
–.000
Because _DLIMIT[1]=2, the traverse
path is restricted by the working area
limitation.
0.000
Distance from C4 in total 4 mm due to
C2 and _DLIMIT[3]. Distance C2 – N3 of
0.1 mm does not lead to limitation of the
traverse path.
21.213
Frame with translation and rotation
active. The permissible traversal path in
_MOVDIST applies in the translated and
rotated coordinate system (WCS).
