2000
BRAKE START TORQUE
(0x7185)
Programmable fault:
Mechanical brake alarm. Alarm
is activated if required motor
starting torque,
, is not achieved.
Check brake open torque setting, parameter
.
Check drive torque and current limits. See
firmware block
on page
.
2001
BRAKE NOT CLOSED
(0x7186)
Programmable fault:
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
.
To determine whether problem is with
acknowledgement signal or brake: Check if
brake is closed or open.
2002
BRAKE NOT OPEN
(0x7187)
Programmable fault:
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
.
To determine whether problem is with
acknowledgement signal or brake: Check if
brake is closed or open.
2003
SAFE TORQUE OFF
(0xFF7A)
Programmable fault:
Safe Torque Off function is
active, i.e. safety circuit
signal(s) connected to
connector X6 is lost while drive
is stopped and parameter
is set to
.
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
setting could not be changed to
value
Contact your local ABB representative.
2005
MOTOR TEMPERATURE
(0x4310)
Programmable fault:
Estimated motor temperature
(based on motor thermal model)
has exceeded alarm limit
defined by parameter
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
and
.
Measured motor temperature
has exceeded alarm limit
defined by parameter
Check that actual number of sensors
corresponds to value set by parameter
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.
