What causes Siemens SINUMERIK alarm 22069?

All tools in the specified tool group are disabled due to tool monitoring (wear limit, breakage detection, or manual disable). Tool group definition in tool table is incomplete or contains no valid tools. Tool data corrupted or not properly loaded into CNC memory. Tool change command references a non-existent tool group number. Tool monitoring has automatically disabled tools exceeding wear or breakage thresholds.

How do I fix Siemens SINUMERIK alarm 22069?

1. Review the tool table and verify the tool group contains at least one tool with enabled status; check tool monitoring settings to confirm tools are not flagged as worn or broken 2. Access the tool management interface and re-enable disabled tools if they are still serviceable, or add new tools to the affected tool group 3. Verify the NC program references the correct tool group number and that the tool group definition matches the intended tools for the operation 4. Reload or backup/restore the tool table from a known good configuration to rule out data corruption 5. Check tool monitoring alarm history and parameter settings (tool life, wear limits) to understand why tools were disabled; adjust thresholds if necessary and re-enable tools
