What does 231-F200 mean?
This error indicates that the Machine Control (MC) unit of the Heidenhain TNC CNC Controller failed to perform a required test of the motor brake line, as mandated by parameter settings. The test might also exceed its maximum allowed duration of 10 seconds. This suggests a potential issue in the electrical circuit controlling the brake, compromising safety by not verifying the integrity and responsiveness of the brake line.
Common Causes
- Incorrect parameter settings requiring a brake line test, where the conditions for its execution are not met or are misinterpreted.
- An issue with the wiring of the motor brake line, such as an open circuit, short circuit, or excessively high resistance.
- A problem with the brake line control output from the drive or safety module, preventing proper signal transmission.
- The brake line test sequence taking longer than the allowed 10 seconds, indicating an electrical fault or a delay in the control signal.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify the controller parameters related to motor brake line testing to confirm that the test is required and that its configuration is correct.
- 2
Perform a thorough inspection of the motor brake line wiring, checking for continuity, insulation integrity, and proper termination at all connection points.
- 3
Measure the voltage and current on the brake line during test activation to ensure correct electrical signals are present and that the line responds as expected.
- 4
Monitor the duration of the brake line test; if it consistently exceeds 10 seconds, investigate for resistance issues, cable damage, or control signal delays.
- 5
If wiring and external components are verified as functional, contact a Heidenhain service agency for diagnostics on the MC unit or the associated safety output module.
