Maximum number of protection areas
The maximum definable number of machine- and channel-related protection zones is set via:
MD18190 $MN_MM_NUM_PROTECT_AREA_NCK (Number of files for machine-related
protection zones)
MD28200 $MC_MM_NUM_PROTECT_AREA_CHAN (Number of files for channel-specific
protection zones)
Coordinates
The coordinates of a protection zone must always be programmed as absolute values with
respect to the reference point of the protection zone. When the protection zone is activated
via the part program it is possible to apply a relative offset to the reference point of the
protection zone.
Examples
In the following figures some examples for protection zones have been presented:
