Access tool management screen (HMI: Services > Tool Management) and verify the magazine status display shows available empty locations.

Compare physical magazine contents with the tool list in the control. Note any discrepancies between actual empty pockets and control data.

Check machine data MD18090 (MM_NUM_MAGAZINE_LOCATION) to verify magazine capacity matches physical magazine pocket count.

Incorrect machine data modification can cause machine malfunction. Document original values before changes.

If mismatches exist, perform a complete tool magazine inventory update or execute a magazine initialization routine to synchronize control data with physical reality.

Magazine initialization will reset all tool location data. Document current tool positions before proceeding.

Navigate to Commissioning > Machine Data and check MD18092 (MM_TYPE_OF_MAGAZINE) for correct magazine type configuration (linear, matrix, chain).

Review the tool list for duplicate pocket assignments by sorting tools by location number. Look for multiple tools assigned to the same magazine position.

Access System Data > Tool Management Files and export/backup current tool management data (TOA, TMA files), then examine for data inconsistencies.

Always create backup before modifying tool management files.

Delete corrupted tool entries or reload tool management database from a known good backup. If no backup exists, manually rebuild tool data with correct location assignments.

Review the active NC program line where the alarm occurred. Identify any GETSELT, T-number calls, or tool change commands with location search parameters.

Verify that any magazine location type specifications in the program (e.g., PSEL, PFRAME parameters) match available magazine configurations defined in machine data.

Check if the program attempts to load a tool into a specific location that is already occupied or restricted. Modify program to allow automatic location selection.

Test with simplified tool change command (standard T-code without location parameters) to verify basic tool management functionality before reintroducing complex search criteria.
