Heidenhain · TNC CNC Controllers
This error indicates that a safety cutout channel test was automatically canceled by the Heidenhain TNC CNC Controller because the maximum permissible delay time was exceeded, or the NC did not properly complete a test section. This signifies a failure in verifying a critical safety switch-off function, potentially leaving a safety circuit unverified or in an unsafe operational state.
Click steps to track your progress.
Check the NC's system error log for any preceding errors that might have led to the cancellation of the test section.
Verify the configured parameters for the cutout channel test, especially any time limits or delay settings, ensuring they are appropriate for the system's expected response time.
Inspect the wiring and functionality of the safety cutout channel components (e.g., contactors, relays, safety modules) for slow operation or mechanical binding.
Verify the software version of the Heidenhain TNC CNC Controller and ensure it is up-to-date and compatible with the safety functions being tested.
If the issue persists, contact a Heidenhain service agency for detailed diagnostics on the NC's internal processing or safety module.
