HEIDENHAIN 230-0424 - DCM
HEIDENHAIN alarm 230-0424 occurs when Dynamic Collision Monitoring (DCM) detects an imminent collision and executes an emergency stop of all axes. This safety feature activates when the machine's actual position deviates from the expected collision-free path or when DCM parameters are incorrectly configured.

HEIDENHAIN 230-0424 - DCM
DCM
Dynamic Collision Monitoring has intervened to stop all axis movements and prevent a mechanical collision. This is a protective safety action.
Root Cause Summary
HEIDENHAIN alarm 230-0424 occurs when Dynamic Collision Monitoring (DCM) detects an imminent collision and executes an emergency stop of all axes. This safety feature activates when the machine's actual position deviates from the expected collision-free path or when DCM parameters are incorrectly configured.
Safety
- Refer to Heidenhain service manual
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Check DCM status display
Navigate to MOD function 'Collision Monitoring' and review the DCM status screen to identify which collision zone was violated.
The violated zone will be highlighted in red on the DCM graphics display
- 2
Verify collision envelope parameters
Check machine parameters MP7440-MP7449 for correct collision monitoring zone definitions and ensure they match your actual machine geometry.
Incorrect collision zones can cause false alarms or inadequate protection
- 3
Reset DCM and test movement
Press the DCM RESET softkey, then manually jog axes slowly to verify proper collision detection boundaries.
Use incremental jog mode with small increments when testing near collision boundaries
Call a technician if:
- ·Collision model files are corrupted
- ·Kinematic parameters require complete reconfiguration
- ·Servo drive hardware faults are detected
Prevention
- Regularly verify DCM collision boundaries during setup
- Maintain accurate tool length measurements
- Perform DCM test runs after any kinematic changes
- Keep collision model files backed up
Common Mistakes
- Disabling DCM to avoid alarms instead of fixing root cause
- Incorrect tool length compensation entries
- Running programs without DCM simulation verification
- Modifying collision parameters without understanding machine geometry
