Access tool table

Press MOD key, select 'Tables' and open TOOL.T table to review active tool entries.

Use F3 to sort by tool number for easier review

Check turret capacity parameter

Navigate to machine parameters and verify MP7680 (number of tool positions) matches physical turret capacity.

Do not modify MP7680 without consulting machine documentation

Remove unused tools from table

Delete or deactivate tool entries that are not currently needed by setting tool length to 0 or removing the entry entirely.

Keep a backup of the tool table before making changes

Reset tool management

Execute M06 T0 to reset tool management system and clear any cached turret status information.

Check turret position display

In Manual mode, press TOOL key to display current turret status and verify actual vs. displayed tool positions.

Compare physical turret positions with TNC display

Execute turret reference cycle

Perform manual reference run for turret axis (typically C-axis) to synchronize position feedback with TNC.

Ensure turret area is clear before referencing

Reset tool change system

Access Service menu and execute 'Reset tool changer' function to clear any pending tool change operations.

This clears the internal tool change state machine

Verify pocket assignment

In TOOL.T table, check POCKET column entries match actual tool locations in turret positions.

Verify turret parameters

Check MP7680 (tool positions), MP7681 (tool change mode), and MP7682 (turret type) in machine parameter list.

Document original values before any changes

Review tool management settings

Examine MP7690-7699 series parameters for tool monitoring and management configuration.

Compare with machine manufacturer specifications

Check PLC interface parameters

Verify MP7700-7710 series parameters that control communication between TNC and turret PLC.

These parameters affect tool position feedback

Restore parameter backup

If parameters were modified, restore from known good backup or contact machine builder for correct values.

Access PLC diagnostics

Enter Service mode and navigate to PLC status display to monitor turret position inputs and outputs.

Look for stuck or inconsistent position signals

Check turret sensors

Verify all turret position sensors and tool presence detectors are functioning correctly and not giving false signals.

Use lockout/tagout procedures when checking sensors

Cycle PLC program

Stop and restart the PLC program to reset any stuck logic states in the turret control routine.

Monitor alarm history during PLC restart

Verify I/O mapping

Confirm PLC input/output assignments for turret control match the actual machine wiring and sensor configuration.
