Access configuration management

Navigate to MOD function → System → Configuration → Axis Configuration to check if axis parameters are present.

Always backup configuration files before making changes using the TNCbackup utility.

Verify CfgAxis file integrity

Check TNC:\system\cfg\CfgAxis.cfg file exists and contains parameter blocks for all configured axes using the file manager.

Do not manually edit configuration files without proper backup - use TNC configuration menus instead.

Restore from backup

If file is corrupted, restore CfgAxis.cfg from a known good backup or recreate axis configuration through Setup → Axis Configuration menu.

Use TNCbackup's selective restore feature to restore only configuration files without affecting part programs.

Restart control system

Perform a complete TNC restart (Ctrl+Alt+Del) to reload the corrected configuration files and clear the alarm.

Ensure all programs are saved before restarting the control.

Access machine parameters

Enter MOD function → Machine Parameters and navigate to the axis-specific parameter group (MP1000-MP1999 range) for the affected axis.

Use the search function in machine parameters to quickly locate specific parameter numbers.

Verify critical axis parameters

Check MP1010 (axis name), MP1020 (reference system), MP1030 (axis type), and MP1040 (display resolution) are properly defined and not set to undefined values.

Changing machine parameters requires proper authorization level and can affect machine safety.

Configure missing parameters

Set undefined parameters to appropriate values based on machine specifications, ensuring all mandatory axis parameters have valid entries.

Reference the machine manufacturer's parameter documentation for correct values specific to your machine configuration.

Save and restart

Save machine parameters and perform a TNC restart to activate the new parameter settings and resolve the configuration error.

Test axis movement carefully after parameter changes to ensure proper operation.

Check software version compatibility

Verify current TNC software version in Setup → General → Software Version and compare with configuration file format requirements.

Keep a log of software versions and corresponding configuration backups for easier troubleshooting.

Run configuration migration utility

Use Setup → System → Configuration → Migration Tool to update configuration files to current software format requirements.

Always create a complete system backup before running migration utilities.

Validate updated configuration

Review migrated axis parameters in MOD → System → Configuration → Axis Configuration to ensure all required parameters are present and correctly formatted.

Compare critical parameters with pre-update backup to ensure no essential settings were lost during migration.

Test axis functionality

Perform controlled axis movements and reference point approach to verify proper axis operation after configuration update.

Use reduced feedrates for initial testing after configuration changes.

Document hardware changes

Identify what hardware components were changed (servo drives, encoders, motors) and gather technical specifications for parameter configuration.

Maintain a hardware change log with part numbers and parameter requirements for future reference.

Update servo parameters

Modify axis-specific parameters in MOD → Machine Parameters → Servo section (MP2000-MP2999) to match new hardware specifications.

Incorrect servo parameters can cause dangerous axis behavior - verify all values with hardware documentation.

Reconfigure axis scaling

Update encoder resolution parameters (MP1040, MP1050) and scaling factors to match new hardware configuration in axis parameter settings.

Use the axis calibration wizard in Setup → Axis Configuration for automatic parameter calculation when available.

Perform axis commissioning

Run complete axis commissioning procedure including reference point setting and axis calibration to validate new hardware configuration.

Establish new reference points carefully and verify axis travel limits after hardware changes.
