Protection zones
3.1 Definition of the protection zones (CPROTDEF, NPROTDEF)
Job planning
218 Programming Manual, 07/2010, 6FC5398-2BP40-0BA0
Meaning
DEF INT NOT_USED: Define local variable, data type INTEGER
(see Chapter "
Motion synchronous actions (Page 549)")
G17/G18/G19: 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.
CPROTDEF: Define channel-specific protection zones (for NCU 572/573
only)
NPROTDEF: Defining machine-specific protection zones
G0/G1/... X/Y/Z...
... :
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.
EXECUTE: End definition
<n>: Number of defined protection zone
Type of protection zone
TRUE: Tool-related protection zone
<t>:
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
<applim>:
3: Limit in positive and negative direction
<applus>: Value of the limit in the positive direction in the 3rd dimension
<appminus>: Value of the limit in the negative direction in the 3rd dimension
NOT_USED: Error variable has no effect for protection zones with EXECUTE
General conditions
During definition of the protection zones:
● no cutter or tool nose radius compensation must be active.
● no transformation must be active.
● no frame must be active.
Neither must reference point approach (G74), fixed point approach (G75), block
preprocessing stop nor program end be programmed.
