Maximum memory space

The maximum value of the memory space in KB that can be allocated to the collision avoidance
is set with the machine data.
MD18896 $MN_MM_MAXNUM_3D_COLLISION = <value>
Value Meaning
0
> 0
Note
Only one > 0 value must be entered in the machine data when one of the following alarms is
displayed:
● Alarm 26262 "Insufficient memory space for the collision check of two protection areas"
● Alarm 26263 "Insufficient memory space for determining the clearance of two protection
areas"
Used memory space
Various system variables are available to determine the memory space used by the collision
avoidance. See section "Memory requirement (Page 274)".
7.2.2.5

Maximum number of collision pairs

The maximum number of possible collision pairs has an impact on:
● Length m of the system variable fields (e.g. $NP_COLL_PAIR[ m, ... ] )
● The user memory required for collision avoidance
● The size of the commissioning archive
The maximum number of collision pairs can be restricted with machine data:
268
The maximum value of the memory space is determined automatically by the control using
the following machine data:
● MD18890 $MN_MM_MAXNUM_3D_PROT_AREAS
● MD18892 $MN_MM_MAXNUM_3D_PROT_AREA_ELEM
● MD18894 $MN_MM_MAXNUM_3D_FACETS_INTERN
● MD18895 $MN_MM_MAXNUM_3D_FACETS
