Plane
The required plane is selected before CPROTDEF and NPROTDEF with G17, G18, G19 and
must not be altered before EXECUTE. The applicate must not be programmed between
CPROTDEF or NPROTDEF and EXECUTE.
Contour elements
The following is permissible:
• G0, G1 for straight contour elements
• G2 for clockwise circle segments (only for tool-oriented protection zones)
• G3 for circular segments in the counterclockwise direction.
Note
With the 810D, a maximum of 4 contour elements are available for defining one
protection zone (max. of 4 channel-specific and 4 NCK-specific protection zones).
If a full circle describes the protection zone, it must be divided into two half circles. The
order G2, G3 or G3, G2 is not permitted. A short G1 block must be inserted, if necessary.
The last point in the contour description must coincide with the first.
External protection zones (only possible for workpiece-related protection zones) must be
defined in the clockwise direction.
For rotation-symmetric protection zones (e.g. spindle chuck), you must describe the
complete contour and not only up to the center of rotation!.
Tool-oriented protection zones must always be convex. If a concave protected zone is
desired, this should be subdivided into several convex protection zones.
