Description
Definition of the protection zones includes the following:
• CPROTDEF for channel-specific protection zones
• NPROTDEF for machine-specific protection zones
• Contour description for protection zone
• Termination of the definition with EXECUTE
You can specify a relative offset for the reference point of the protection zone when the
protection zone is activated in the NC parts program.
Reference point for contour description
The workpiece-oriented protection zones are defined in the basic coordinate system. The
tool-oriented protection zones are defined with reference to the tool carrier reference point F.
Contour definition of protection zones
The contour of the protection zones is specified with up to 11 traversing movements in the
selected plane. The first traversing movement is the movement to the contour. The valid
protection zone is the zone left of the contour. The travel motions programmed between
CPROTDEF or NPROTDEF and EXECUTE are not executed, but merely define the
protection zone.

Defining machine-specific protection zones
End definition
Number of defined protection zone
TRUE = Tool-related protection zone
FALSE = workpieceprotection zone
Type of limitation in the third dimension
0 = No limit
1 = Limit in positive direction
2 = Limit in negative direction
3 = Limit in positive and negative direction
Value of the limit in the positive direction in the 3rd
dimension
Value of the limit in the negative direction in the 3rd
dimension
Error variable has no effect in protection zones with EXECUTE
