The control system issues an alarm indicating an issue with the CNC lock function's activation, extension, or deactivation file. This happens when the file contains incorrect or unsupported data, such as a wrong version or an incorrect serial number.
Click steps to track your progress.
Verify that the .clc file version is compatible with the control system's requirements.
Check that the serial number of the CF card, as recorded in the .clc file, is accurate.
If the alarm persists, contact the machine manufacturer or dealer to create and import a new, correct activation file.
For other CNC lock alarms (8062-8066), consult the machine manufacturer or dealer for specific troubleshooting.
