12.32.4 The motion axes of a protection zone
If a protection zone is to be able to follow a moving machine part, e.g. a tool slide, the real
machine axes that move the machine part must assigned to the protection zone. These axes
are the motion axes of the protection zone.
The axes must exist and be in the same mode group.
In the event of an error, alarm 111 ”Error in collision monitoring data” is output with the code
01=motion axis does not exist
or
02=motion axis not in the same mode group.

12.32.5 Machine coordinate systems
To permit mutual monitoring of protection zones that are in different machine coordinate
systems within a machine tool, the two coordinate systems must be transformed into a
common coordinate system (monitoring coordinate system). The common coordinate system
can be any machine coordinate system.
(Collision monitoring only works with the machine coordinate systems that are not rotated with
respect to one another but only translated and/or mirrored.)
Each protection zone must therefore be assigned to a machine coordinate system by machine
data.
