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:
