Access machine parameters

Press MOD key, select 'Machine parameters' from the TNC menu, navigate to 'System/CfgMachineSimul' branch.

Use the search function in machine parameters by typing 'skipReferencing' to quickly locate the parameter.

Check skipReferencing parameter

Locate parameter 'skipReferencing' and verify its current value. If set to TRUE, this is causing the alarm.

Document current parameter settings before making changes.

Set parameter to FALSE

Change 'skipReferencing' parameter from TRUE to FALSE, then save the machine parameters.

After changing, perform a complete machine restart to ensure parameter takes effect.

Execute reference run

Perform manual reference run on all axes using the reference point approach function in manual mode.

Ensure machine area is clear before executing reference run.

Check DCM activation status

Navigate to 'Setup/DCM' menu and verify if Dynamic Collision Monitoring is active. Check DCM parameter settings in machine parameters.

Look for DCM status indicator in the TNC status bar.

Verify simulation mode settings

Check machine parameter 'CfgMachineSimul' branch for other simulation-related parameters that may conflict with DCM operation.

Simulation mode and DCM cannot operate simultaneously.

Disable simulation or DCM

Either disable DCM functionality or exit simulation mode by setting appropriate machine parameters to resolve the conflict.

If running production, disable simulation mode. If testing programs, temporarily disable DCM.

Restart TNC system

Perform complete TNC restart to ensure all parameter changes take effect and clear any cached simulation states.

Save all active programs before restarting the system.

Review recent system changes

Check TNC event log for recent software updates, parameter changes, or backup restorations that may have affected machine configuration.

Access event log through 'Setup/General/Event log' to trace recent system activities.

Compare with backup parameters

If available, compare current machine parameters with a known good backup to identify discrepancies in the CfgMachineSimul branch.

Only restore parameters from verified working backups.

Reset simulation parameters

Set 'skipReferencing' to FALSE and verify all other simulation-related parameters are configured for normal machine operation.

Document parameter changes for future reference and troubleshooting.

Validate DCM functionality

After correcting parameters and referencing axes, test DCM operation with a simple program to ensure collision monitoring is working properly.

Use slow feed rates during initial DCM validation tests.

Review commissioning checklist

Check if machine commissioning was completed properly, specifically the transition from setup mode to production mode parameters.

Commissioning often uses skipReferencing=TRUE for initial setup convenience.

Verify axis reference marks

Ensure all axis reference marks are properly configured and functional before disabling skipReferencing parameter.

Faulty reference marks can cause machine crashes when skipReferencing is disabled.

Complete production setup

Set skipReferencing to FALSE, configure all production parameters, and establish proper machine coordinate system.

Create a commissioning completion checklist to avoid similar issues in the future.

Test all machine functions

Perform comprehensive testing of referencing, DCM, and all axis movements to ensure proper machine operation in production mode.

Test at reduced speeds initially to verify all systems are functioning correctly.
