130-0136

Access Service Mode

Power off the control completely. Power on while holding the MOD key to enter Service Mode. This bypasses normal startup and allows access to recovery functions.

If MOD key access fails, the system partition itself may be damaged and require Heidenhain service intervention.

Check System Log Files

In Service Mode, navigate to System > Log Files. Review the startup log (syslog.txt) and look for specific object names or initialization failures that caused the 130-0136 alarm.

Take photos or notes of specific missing object names - this information is critical for determining if a full reinstall is needed.

Attempt System Restore

From Service Mode menu, select 'Restore System' if a recovery partition exists. Choose the most recent stable system restore point before the failed update or installation.

System restore will revert to the previous software version and may lose recent configuration changes not backed up.

Reinstall NC Software

If restore fails, perform complete NC software reinstallation using Heidenhain installation media (USB or DVD). Boot from installation media and select 'Complete Installation' option. Follow prompts to reinstall all system objects.

Ensure you have machine parameters and PLC program backups before reinstalling. Machine-specific data must be reloaded after fresh installation.

Restore Machine Configuration

After successful reinstallation, restore machine parameters from TNC:\system\backup or external backup media. Reload PLC program and cycle definitions specific to your machine.

Use MOD > File System to verify all required files in TNC:\system\objects directory are present with valid timestamps after installation.

Boot to Service Mode Diagnostics

Enter Service Mode (MOD key at power-up). Navigate to Diagnostics > Hard Disk Test. Run the complete disk integrity check to identify bad sectors or file system errors.

Disk check may take 20-60 minutes depending on disk size. Do not interrupt the process.

Review Disk Health Status

Check the S.M.A.R.T. status in Service Mode under System Info > Storage Device. Look for reallocated sectors, pending sectors, or error counts indicating drive failure.

Any S.M.A.R.T. warnings or error counts above zero indicate the drive should be replaced preventatively.

Attempt File System Repair

If disk check reports file system errors but hardware is OK, use Service Mode > System Tools > File System Repair. This runs fsck utility to repair directory structure and recover damaged files.

File system repair may recover enough objects to allow booting, but plan for disk replacement if errors are found.

Replace Storage Device

If disk diagnostics show hardware failure or repair attempts fail, replace the hard disk/SSD with Heidenhain-approved replacement. Use SSD for TNC 620/640 controls for improved reliability.

Only use storage devices qualified by Heidenhain. Consumer-grade drives may lack industrial temperature ratings or write-endurance required for CNC operation.

Install Fresh System

On new storage device, perform complete NC software installation from Heidenhain media. After installation, restore all machine-specific configuration from external backup.

Document the software version installed and keep installation media version synchronized with your machine's PLC and option requirements.

Verify Backup Source Integrity

Access Service Mode and check the backup archive used for restoration. Verify the backup date, software version, and file count. Compare against a known-good backup if available.

Heidenhain system backups should be 500MB-2GB typically. Significantly smaller files indicate incomplete backup archives.

Check Software Version Compatibility

In Service Mode > System Info, verify the NC software version matches the version from which the backup was created. Cross-version restores often cause object mismatches.

Restoring backups across major version changes (e.g., 340xxx to 640xxx) will fail. Version must match within the same branch.

Restore from Alternative Backup

If available, use an older verified backup or the factory default backup stored in recovery partition. Navigate to Service Mode > Restore System > Select Backup Archive and choose alternative source.

The recovery partition typically contains a factory-fresh system backup that always boots, though it lacks machine-specific configurations.
