Access Tool Management

Navigate to HMI → Machine → Tool Management → Tool Adapters to verify if the referenced TA exists in the system database.

Check TA Number Range

Verify the TA number falls within the configured range defined in machine data MD18118 (MM_NUM_TOOL_ADAPTER) and MD18119 (MM_TOOL_ADAPTER_PRESEL).

SINUMERIK systems typically support TA numbers 1-9999, but your machine configuration may limit this range.

Create Missing TA Entry

If TA is missing, create new tool adapter entry with correct geometry data including length offset, radius compensation, and orientation parameters.

Ensure machine is in safe position before modifying tool adapter data.

Verify TA Parameters

Check that all mandatory TA parameters are populated including $TA_DP1 through $TA_DP6 geometry values and $TA_TYPE adapter type definition.

Check Database Integrity

Navigate to Diagnostics → Service → Tool Management and run database consistency check to identify corrupted TA entries.

Backup Current Data

Create backup of current tool management data via HMI → Commissioning → Data Backup → Tool Data before attempting repairs.

Always backup to external USB device to prevent data loss during recovery procedures.

Reset Tool Adapter Table

Clear corrupted TA table using NC command $A_TOOLMN[0]=0 followed by system restart to reinitialize tool adapter database structure.

Restore TA Definitions

Manually re-enter tool adapter definitions or restore from previous backup file through Data Restore function in commissioning menu.

Identify Program Location

Check the NC program line where alarm occurred, typically visible in alarm display showing the specific TA number that caused the error.

Verify TA Call Syntax

Ensure proper SINUMERIK syntax for tool adapter calls using T=tool_number with corresponding TA assignment in tool data table.

Cross-Reference Tool Data

Navigate to Tool Management → Tools and verify that the tool being called has correct TA assignment matching available tool adapters.

Use F8 search function in tool table to quickly locate specific tool numbers and their TA assignments.

Correct Program Reference

Modify NC program to reference existing TA number or update tool data to assign correct tool adapter for the specified tool.

Check Tool Management MDs

Verify MD18110 (MM_NUM_TOOL) and MD18118 (MM_NUM_TOOL_ADAPTER) are set to appropriate values for your machine configuration.

Validate Memory Allocation

Ensure sufficient memory is allocated for tool adapter data by checking MD18050 (MM_TOOL_MANAGEMENT_MASK) bit settings for TA functionality.

Changing machine data requires NCK restart and may affect other machine functions.

Reset Tool Management

If MD changes are required, perform controlled NCK restart via HMI → Commissioning → Start-up → NCK Reset after saving current settings.

Verify TA Functionality

Test tool adapter recognition by manually creating a test TA entry and verifying it appears correctly in tool management display.

Check System Integrity

Run SINUMERIK system diagnostics via Service menu to identify missing or corrupted tool management components.

Verify File System

Check NCK file system integrity using diagnostic functions to ensure all tool management related files are present and accessible.

Document any error messages for Siemens technical support if system file restoration is required.

Restore System Files

If corruption is confirmed, restore from system backup or contact Siemens support for system file recovery procedures.

System file restoration may require factory reset and complete machine reconfiguration.
