Reference
• Tool-related protection zones
• Workpiece-related protection zones
Orientation
The orientation of the protection zones is determined by the plane definition
(abscissa/ordinate), in which the contour is described, and the axis perpendicular to the
contour (vertical axis).
The orientation of the protection zones must be the same for the tool and workpiecerelated
protection zones.
2.2.2 Types of protection zone
Machine-defined and channel-defined protection zones
• Machine-defined protection zone
• Channel-defined protection zones
Example: Doubleslide turning machine
• The toolrelated protection zones are assigned to channel 1 or 2.
• The workpiecerelated protection zones are assigned to the machine.
• The coordinate system must be identical for both channels.
Basic logic functions: Axis monitoring, protection zones (A3)
Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Coordinates for toolrelated protection zones must be given as absolute values referred to
the tool carrier reference point F.
Coordinates for workpiecerelated protection zones must be given as absolute values
referred to the zero point of the basic coordinate system.
Note
If no toolrelated protection zone is active, the tool path is checked against the workpiece-
related protection zones.
If no workpiece-oriented protection zone is active, protection-zone monitoring does not
take place.
Data for machine-related protection zones are defined once in the control. These
protection zones can be activated by all channels.
Data for channel-related protection zones are defined in a channel. These protection
zones can be activated only by this channel.
