4.1 Definition of the protection zones (CPROTDEF, NPROTDEF)
Job planning
4-2 Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
EXECUTE(NOT_USED)
Parameters
DEF INT NOT_USED Define local variable, data type integer (see Motion-
synchronous action section)
CPROTDEF Define channel-specific protection zones (for NCU 572/573 only)
NPROTDEF Defining machine-specific protection zones
EXECUTE End definition
n Number of defined protection zone
t
TRUE = Tool-related protection zone
FALSE = workpieceprotection zone
applim 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
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 in protection zones with EXECUTE
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.
