Collision avoidance
Note
Referenced axes
The positions of the axes in the machine area must be known so that the protection areas can
be monitored. For this reason, collision avoidance is only active after the referencing.
NOTICE
No complete machine protection
Incomplete models, e.g. machine parts, workpieces that have not been modeled or new
objects in the working area, are not monitored and can therefore cause collisions.
