Protection zones

4.2 Activating, deactivating protection zones (CPROT, NPROT)

During definition of the protection zones
• no cutter or tool nose radius compensation,
• no transformation,
• no frame must be active.
Nor must reference point approach (G74), fixed point approach (G75), block search stop or
program end be programmed.
4.2 Activating, deactivating protection zones (CPROT, NPROT)
4.2
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.
