General 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 (for NCU 572/573
only)
Defining 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 motion programmed between
