Detailed Description
2.4 Protection zones
Axis Monitoring, Protection Zones (A3)
2-40 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Deactivation
A protection zone can be deactivated from a part program only.
RESET response
The activation status of a protection zone is retained even after NC-RESET and program end.
Memory requirements
The memory requirements with regard to protection zones are defined with the following
parameters:
• Maximum number of protection zones that can be simultaneously activated in the
channel:
MD28210 $MC_MM_NUM_PROTECT_AREA_ACTIVE
• Maximum number of contour elements that can be defined per protection zone:
MD28212 $MC_MM_NUM_PROTECT_AREA_CONTUR
Deactivation, preactivation, activation via part program
The activation status of a channel- or machine-specific protection zone is defined by the
corresponding subroutine:
• Channel-specific protection zone:
CPROT (n, state, xMov, yMov, zMov)
• Machine or NC-specific protection zone:
NPROT (n, state, xMov, yMov, zMov)
Parameters Type Description
n INT
Number of the protection zone
state INT
Activation status
0: Deactivated
1: Preactivated
2: Enabled
xMov,
yMov, zMov
REAL
Offset values of the previously defined protection zone in the geometry axes
Offsets
During preactivation or activation of the protection zone, an offset can be entered in 0 to 3
dimensions. The offset refers to:
• Workpiece-specific protection zones: Machine zero
• Tool-specific protection zones: Tool holder reference point F
Note
A protection zone cannot be activated in a single channel with different offsets
simultaneously.
