Cause : Mechanical brake control fault. Activated e.g., if brake acknowledgment is not as expected during brake closing.
1. Check mechanical brake connection.
2.Check mechanical brake settings in
parameter group 44 - Mechanical brake control.
3. Check that the acknowledgment signal matches the actual status of the brake.
