Alarm messages generated by the drive
Code Alarm
(fieldbus code)
Cause What to do
2000 BRAKE START TORQUE
(0x7185)
Programmable fault: 35.09
BRAKE FAULT FUNC
Mechanical brake alarm. Alarm
is activated if required motor
starting torque, 35.06 BRAKE
OPEN TORQ, is not achieved.
Check brake open torque setting, parameter
35.06.
Check drive torque and current limits. See
firmware block LIMITS on page 127.
2001 BRAKE NOT CLOSED
(0x7186)
Programmable fault: 35.09
BRAKE FAULT FUNC
Mechanical brake control alarm.
Alarm is activated e.g. if brake
acknowledgement is not as
expected during brake closing.
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.
2002 BRAKE NOT OPEN
(0x7187)
Programmable fault: 35.09
BRAKE FAULT FUNC
Mechanical brake control alarm.
Alarm is activated e.g. if brake
acknowledgement is not as
expected during brake opening.
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.
2003 SAFE TORQUE OFF
(0xFF7A)
Programmable fault: 46.07
STO DIAGNOSTIC
Safe Torque Off function is
active, i.e. safety circuit
signal(s) connected to
connector X6 is lost while drive
is stopped and parameter 46.07
STO DIAGNOSTIC is set to (2)
ALARM.
Check safety circuit connections. For more
information, see appropriate drive hardware
manual.
2004 STO MODE CHANGE
(0xFF7A)
Error in changing Safe Torque
Off supervision, i.e. parameter
46.07 STO DIAGNOSTIC
setting could not be changed to
value (2) ALARM.

2005 MOTOR TEMPERATURE
(0x4310)
Programmable fault: 45.01
MOT TEMP PROT
Estimated motor temperature
(based on motor thermal model)
has exceeded alarm limit
defined by parameter 45.03
MOT TEMP ALM 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.
Check motor thermal model settings,
parameters 45.06…45.08 and 45.10 MOT
THERM TIME.
Measured motor temperature
has exceeded alarm limit
defined by parameter 45.03
MOT TEMP ALM LIM.
Check that actual number of sensors
corresponds to value set by parameter 45.02
MOT TEMP SOURCE.
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.
