Cause : Mechanical brake control alarm. Alarm is 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
