Protection zones
3.1 Definition of the protection zones (CPROTDEF, NPROTDEF)
Meaning
DEF INT NOT_USED:
G17/G18/G19:
CPROTDEF:
NPROTDEF:
G0/G1/... X/Y/Z...
... :
EXECUTE:
<n>:
<t>:
<applim>:
<applus>:
<appminus>:
NOT_USED:

Define local variable, data type INTEGER
(see Chapter "Motion synchronous actions [Page 559]")
The required plane is selected before CPROTDEF or
NPROTDEF with G17/G18/G19 and must not be altered
before EXECUTE. The applicate must not be programmed
between CPROTDEF or NPROTDEF and EXECUTE.
Define channel-specific protection zones (for NCU 572/573
only)
Defining machine-specific 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.
Note:
The travel motion programmed between CPROTDEF or
NPROTDEF and EXECUTE are not executed, but merely define
the protection area.
End definition
Number of defined protection zone
Type of protection zone
TRUE: Tool-related protection zone
FALSE: Workpiece-related protection zone
Type of limitation in the third dimension
0: No limitation
1: Limit in plus direction
2: Limit in minus 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 for protection zones with
EXECUTE
