Supplementary 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.

Define channel-specific protection zones
Define machine-specific 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.
Note:
The travel motions programmed between
and are not executed, but merely define the protection
