Cause : Mechanical brake control fault. Activated e.g. if brake acknowledgement is not as expected during brake closing.
Programmable fault:
42.12 Brake fault function
Check mechanical brake connection.
Check mechanical brake settings in
parameter group 42 Mech brake ctrl.
To determine whether problem is with
acknowledgement signal or brake, check
if brake is closed or open
