3.2 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.
Syntax
CPROT(<n>,<state>,<xMov>,<yMov>,<zMov>)
NPROT(<n>,<state>,<xMov>,<yMov>,<zMov>)
Meaning
CPROT: Call channel-specific protection zone (for NCU 572/573 only)
NPROT: Call machine-specific protection zone
<n>: Number of the protection zone
Status parameter
0: Deactivate protection zone
1: Preactivate protection zone
2: Activate protection zone
<state>:
3: Preactivate protection zone with conditional stop
<xMov>,<yMov>,<zMov>: Move defined protection zone on the geometry axes
General conditions
Protection zone monitoring for active tool radius compensation
For active tool radius compensation, a functioning protection zone monitoring is only
possible if the plane of the tool radius compensation is identical to the plane of the protection
zone definitions.
