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, eg, if brake
acknowledgement is not as
35.09
expected during brake closing.
Mechanical brake control alarm.
Alarm is activated, eg, if brake
acknowledgement is not as
35.09
expected during brake opening.
Safe Torque Off function is
active, ie, safety circuit signal(s)
connected to connector X6 is
46.07
lost while drive is stopped and
parameter 46.07 STO
DIAGNOSTIC is set to
Alarm.
Estimated motor temperature
(based on motor thermal model)
has exceeded alarm limit
45.01
defined by parameter
MOT TEMP ALM
Measured motor temperature
has exceeded alarm limit
defined by parameter
MOT TEMP ALM
Drive has received emergency
OFF2 command.
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 and Application guide - Safe torque
off function for ACSM1, ACS850 and
ACQ810 drives (3AFE68929814 [English]).

Check motor ratings and load.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
45.03
surfaces, etc.
LIM.
Check value of alarm limit.
Check motor thermal model settings,
parameters
THERM
Check that actual number of sensors
corresponds to value set by parameter
45.03 MOT TEMP
LIM.
Check motor ratings and load.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
Check value of alarm limit.
To restart drive, activate RUN ENABLE signal
(source selected by parameter
ENABLE) and start drive.
