HEIDENHAIN 292-001D - DCM inactive: Facing-slide kinematics are activated
Alarm 292-001D occurs when DCM (Dynamic Collision Monitoring) is automatically deactivated due to facing-slide kinematics being active in the machine configuration. The TNC system disables collision monitoring because facing-slide operations involve complex rotational movements that the standard DCM algorithms cannot properly monitor.

HEIDENHAIN 292-001D - DCM inactive: Facing-slide kinematics are activated
DCM inactive: Facing-slide kinematics are activated
DCM monitoring is disabled because facing slide kinematics have been activated.
Root Cause Summary
Alarm 292-001D occurs when DCM (Dynamic Collision Monitoring) is automatically deactivated due to facing-slide kinematics being active in the machine configuration. The TNC system disables collision monitoring because facing-slide operations involve complex rotational movements that the standard DCM algorithms cannot properly monitor.
Safety
- Refer to Heidenhain service manual
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Check kinematic configuration
Access MOD function → Machine Parameters → MP7500 KINEMATICS_TYPE and verify if facing-slide kinematics are configured.
Document current kinematic settings before making changes
- 2
Review machine setup requirements
Consult machine documentation to determine if facing-slide kinematics are actually required for current operations.
Changing kinematic models requires machine geometry recalibration
- 3
Evaluate DCM necessity
If DCM is required, consider switching to standard 5-axis kinematics via MP7500 if machine setup permits.
Standard kinematics allow DCM while maintaining most rotary axis functionality
Call a technician if:
- ·Kinematic model changes require machine recalibration
- ·Uncertainty about correct kinematic configuration for specific machine
Prevention
- Document kinematic configuration before software updates
- Verify parameter backups include kinematic settings
- Establish procedures for collision monitoring when DCM is unavailable
Common Mistakes
- Attempting to manually enable DCM while facing kinematics are active
- Changing kinematic model without proper machine recalibration
- Ignoring collision risks when DCM protection is unavailable
