Verify Tool Table Contents

Press the TOOL TABLE soft key (or access via Programming and Editing > Tool Table). Review all tool entries to confirm the imported data matches expectations, checking tool numbers, geometries, and compensation values.

Use the search function (F5 key) in the tool table to quickly locate specific tool numbers if many entries were imported.

Check Import Source File

Press PGM MGT key, navigate to TNC:\ or the external storage location, and verify the timestamp and size of the .T file that was imported to ensure it was the correct version.

The control automatically creates backup files with .Tbak extension - compare these if data appears incorrect.

Acknowledge and Clear

Press the CE key to acknowledge the message. The control will return to normal operation with the newly inserted tool data active.

Do not continue machining until tool data has been verified - incorrect tool length or radius values can cause collisions.

Access Preset Table

Press the POS key (or MOD > Preset Table depending on control version). Review the preset entries, checking fixture offsets and reference point coordinates for all active workpiece positions.

On iTNC 530 and TNC 620/640, preset tables can have multiple pages - use the PAGE soft key to view all entries.

Verify Reference Point Validity

Compare the inserted preset values against the current workpiece setup or CAM documentation. Confirm datum shift values (especially Z-axis) match the physical fixture configuration.

Incorrect preset data is a leading cause of scrapped parts and fixture collisions - always verify before running production.

Test with Dry Run

Execute the NC program in single-block mode with dry run and feed override at 10% to verify the preset data produces correct tool paths before full-speed operation.

Review System Event Log

Navigate to MOD > Service (enter service password if required) > Message Display. Review the chronological list of insertion events to identify which configuration objects were affected.

Use the filter function to display only 140-series messages to isolate all data object operations from the same session.

Check Machine Parameters

Access MOD > Machine Parameters and review critical settings, particularly axis configuration (MP1xxx series), feed rates (MP2xxx), and tool changer parameters (MP7xxx for relevant controls).

Incorrect machine parameters can cause serious mechanical damage - do not operate machine until verified by qualified service personnel.

Verify PLC Program Version

In MOD > Service, check the PLC program version and date. If configuration was restored, ensure PLC software matches the machine manufacturer's specification for your specific machine model.

Document the PLC version before and after any restore operation - version mismatches are often responsible for auxiliary function failures.

Perform Reference Point Test

Execute a controlled reference point approach for all axes. Verify proper homing sequence and encoder position matching to confirm axis configuration parameters are correct.

Check Network Configuration

Navigate to MOD > Network Settings (or Communication Settings on older controls). Review active network connections, shared directories, and any configured data synchronization services.

On TNC 640, check the StateMonitor or RemoTools connection status to identify which external system initiated the data transfer.

Review Data Exchange Settings

In MOD > Extended Settings, verify the 'Data Exchange' or 'Network Data Transfer' settings. Check if automatic synchronization is enabled and which data objects are configured for remote updates.

Automatic network updates can overwrite manually entered tool or preset data without explicit operator confirmation - document local settings before they are replaced.

Validate Source System Data

Log into the upstream tool management or MES system and verify that the transmitted data matches the production requirements and current workpiece setup specifications.

Implement version control or change tracking in your tool management system to maintain an audit trail of all data pushed to machine controls.
