Activating/deactivating protection zones (CPROT, NPROT)

Function
Activating and preactivating previously defined protection zones for collision monitoring and
deactivating protection zones.
The maximum number of protection zones, which can be active simultaneously on the same
channel, is defined in machine data.
If no tool­related protection zone is active, the tool path is checked against the workpiece-
related protection zones.
Note
If no workpiece-related protection zone is active, protection zone monitoring does not take
place.

if the plane of the tool radius compensation is identical to the plane of the protection zone
definitions.
