Access Tool Table

Press MOD key, select 'Tables' then 'Tool table' or directly access via TOOL CALL menu to open TOOL.T table.

Use Ctrl+F to quickly search for specific tool numbers in large tool tables

Verify Tool Number

Check the tool number displayed in the alarm message (%2 parameter) and confirm if this tool number exists in the TOOL.T table.

Ensure spindle is stopped before checking tool numbers

Create Tool Entry

If tool is missing, create new entry in TOOL.T with correct tool number, length (L), radius (R), and other required parameters like tool type and cutting data.

Copy similar tool entries and modify parameters to save time

Validate Tool Data

Execute TOOL CALL with the newly created tool number to verify the entry is properly recognized by the control.

Always perform dry run after adding new tool entries

Check Physical Tool ID

Examine the physical tool holder or tool identification system to determine the actual tool number present in the spindle/turret position.

Lock out spindle rotation before manual inspection

Compare with Program

Review the active NC program and check which tool number is being called via TOOL CALL or T command at the point where alarm occurred.

Use the program trace function to identify exact line where tool call failed

Correct Tool Assignment

Either replace physical tool with correct number or update the NC program to call the correct tool number that matches the physical tool.

Use tool management functions in Setup menu to reassign tool positions if available

Update Tool Position Table

If using tool changer, verify and update the tool position table (TOOLTAB.TAB) to reflect correct tool locations.

Incorrect tool position data can cause crashes during automatic tool changes

Check File Integrity

Navigate to file manager (PGM MGT key) and verify TOOL.T file exists in TNC:\table\ directory and check file size/date.

Compare file size with backup copies to identify potential corruption

Attempt File Recovery

Try opening TOOL.T in text editor mode to check for formatting errors or corruption. Look for proper column headers and data structure.

Always backup current file before attempting repairs

Restore from Backup

If file is corrupted, restore TOOL.T from most recent backup or copy from another identical machine setup.

Check automatic backup directory TNC:\backup\ for recent tool table versions

Rebuild Tool Table

If no backup available, recreate tool table entries manually using MOD > Tables > Tool table, entering all active tools with proper parameters.

Verify all tool length and radius values carefully to prevent collisions

Check DNC Connection

Verify network connection and communication status with external tool management system via Setup > Communication settings.

Use ping function in TNC network diagnostics to test connectivity

Force Tool Data Sync

Initiate manual synchronization between external tool management system and TNC tool table through DNC interface or tool management software.

Ensure no programs are running during synchronization process

Verify Data Transfer

Compare tool entries in TNC TOOL.T table with external database to confirm all required tools are properly transferred with correct parameters.

Export both databases to compare side-by-side for discrepancies

Reset Tool Management

If sync continues to fail, restart tool management services and re-establish communication protocols between systems.

Coordinate with IT/network administrator for system-level changes
