Cause
Mechanical brake alarm. Alarm
is activated if required motor
starting torque, 35.06 BRAKE
35.09
OPEN TORQ, is not achieved.
Mechanical brake control alarm.
Alarm is activated e.g. if brake
acknowledgement is not as
35.09
expected during brake closing.
Mechanical brake control alarm.
Alarm is activated e.g. if brake
acknowledgement is not as
35.09
expected during brake opening.

What to do
Check brake open torque setting, parameter
35.06.
Check drive torque and current limits. See
firmware block
Check mechanical brake connection.
Check mechanical brake settings, parameters
35.01...35.09.
To determine whether problem is with
acknowledgement signal or brake: Check if
brake is closed or open.
Check mechanical brake connection.
Check mechanical brake settings, parameters
35.01...35.08.
To determine whether problem is with
acknowledgement signal or brake: Check if
brake is closed or open.
Check safety circuit connections. For more
information, see appropriate drive hardware
manual.
