Heidenhain 292-0013 - General system error in the collision monitoring
This alarm stems from an internal software fault within the Dynamic Collision Monitoring subsystem, typically caused by configuration data corruption, version mismatch between DCM software and control firmware, or inconsistent kinematic definitions. The collision monitoring system cannot complete its safety calculations due to invalid data or processing errors, forcing a protective shutdown of the DCM functionality.

Heidenhain 292-0013 - General system error in the collision monitoring
General system error in the collision monitoring
Alarm 292-0013 indicates a general system error within the Dynamic Collision Monitoring (DCM) software module on Heidenhain TNC controls. This alarm occurs when the collision monitoring system encounters an internal calculation error, configuration inconsistency, or software exception that prevents proper collision detection functionality from operating correctly.
Root Cause Summary
This alarm stems from an internal software fault within the Dynamic Collision Monitoring subsystem, typically caused by configuration data corruption, version mismatch between DCM software and control firmware, or inconsistent kinematic definitions. The collision monitoring system cannot complete its safety calculations due to invalid data or processing errors, forcing a protective shutdown of the DCM functionality.
Safety
- Refer to Heidenhain service manual
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Access Collision Monitoring Configuration
Press MOD key, navigate to Settings > Collision Monitoring. Document current settings including all active collision objects and fixture definitions before making changes.
- 2
Check Configuration File Integrity
Navigate to MOD > File Management > TNC:\system\dcm\ directory. Verify DCM.CFG and associated collision object files (.DCM extension) are present and have valid timestamps. Look for files with zero byte size or recent unexpected modification dates.
Use the control's file compare function against a known good backup from when collision monitoring last worked properly.
- 3
Restore Configuration Backup
If backup exists in TNC:\backup\ directory, copy the DCM configuration files from backup to the system\dcm\ directory. Perform a full power cycle (not just control restart) after file restoration.
Always backup current files before overwriting, even if corrupted, for diagnostics.
- 4
Rebuild Collision Configuration
If no valid backup exists, deactivate collision monitoring, delete all DCM files, and rebuild the collision monitoring setup using Settings > Collision Monitoring > Configuration. Re-enter all machine components, fixtures, and collision objects according to machine builder specifications.
Start with minimal collision objects (spindle and table only) to isolate which component definition causes the error.
Call a technician if:
- ·Hardware module replacement needed
- ·Persistent errors after parameter reset
- ·Complex collision model reconstruction required
Prevention
- Regular backup of collision model files
- Monitor system resource usage during complex operations
- Periodic verification of DCM parameter integrity
- Avoid unauthorized collision model modifications
Common Mistakes
- Deleting collision models without backups
- Setting DCM cycle time too aggressive
- Ignoring system resource warnings
- Modifying collision parameters without documentation
