Access tool management list via HMI: Services > Tool Management > Tool List

Check total number of tool entries against system limit (typically 255 or 512 depending on configuration). Review machine data MD18118 $MN_MM_NUM_TOOL for maximum tool limit.

Delete unused, duplicate, or obsolete tool entries to free memory locations. Ensure tools are not currently active in magazines before deletion.

Always backup tool management data before deleting entries using archive functions

If all tools are needed, verify MD18118 setting allows sufficient tool slots and consider increasing if hardware license permits. Reset control after MD changes.

Machine data changes require access level 2+ and full control restart

Check available NC memory: Program Manager > Memory Display or check area 'User Memory' in diagnostics to view free/used NC memory percentage.

Delete obsolete NC programs, old test programs, and backup copies from NC memory (not CompactFlash). Archive important programs to CF card or network drive first.

Verify programs are not referenced by production cycles before deletion

Compress NC memory via Services > Memory > Compress function to recover fragmented space after deletions.

Review MD18210 $MN_MM_USER_MEM_SIZE to verify NC user memory allocation is appropriate. Compare against MD18200 $MN_MM_NUM_USER_MEM to ensure sufficient partitions exist.

Changing memory machine data requires cold restart and may affect existing data structure

Access magazine overview: Services > Tool Management > Magazine. Check all magazine locations for occupancy status and verify against physical magazine.

Identify and remove phantom tool entries (tools shown in magazine but not physically present) using magazine reset or individual location deletion functions.

Execute magazine synchronization function if available to match control database with actual magazine sensor status.

Magazine synchronization may require machine to be in reference position with magazine stopped

Check MD18168 $MN_MM_NUM_MAGAZINE_LOCATION and related magazine configuration MDs to ensure location table size matches physical magazine capacity. Verify PLC interface signals for magazine status.

Magazine machine data must match PLC program configuration to avoid location conflicts
