324 Fault tracing
0032 OVERSPEED
(0x7310)
Motor is turning faster than
highest allowed speed due
to incorrectly set minimum/
maximum speed,
insufficient braking torque or
changes in load when using
torque reference.
Check minimum/maximum speed
settings, parameters 20.01 Maximum
speed and 20.02 Minimum speed.
Check adequacy of motor braking torque.
Check applicability of torque control.
0036 LOCAL CTRL LOSS
(0x5300)
Programmable fault: 30.03
Local ctrl loss
Control panel or PC tool
selected as active control
location for drive has
ceased communicating.
Check PC tool or control panel
connection.
Check control panel connector.
Replace control panel in mounting
platform.
0037 NVMEM CORRUPTED
(0x6320)
Drive internal fault
Note: This fault cannot be
reset.
Contact your local ABB representative.
0038 OPTIONCOMM LOSS
(0x7000)
Communication between
drive and option module
(FIO-xx) is lost.
Check that option modules are properly
connected to Slot 1 and (or) Slot 2.
Check that option modules or Slot 1/2
connectors are not damaged. To
determine whether module or connector
is damaged: Test each module
individually in Slot 1 and Slot 2.
0045 FIELDBUS COMM
(0x7510)
Programmable fault: 50.02
Comm loss func
Cyclical communication
between drive and fieldbus
adapter module or between
PLC and fieldbus adapter
module is lost.
Check status of fieldbus communication.
See appropriate User’s Manual of
fieldbus adapter module.
Check settings of parameter group 50
Fieldbus.
Check cable connections.
Check if communication master is able to
communicate.
0046 FB MAPPING FILE
(0x6306)
Drive internal fault Contact your local ABB representative.
0047 MOTOR OVERTEMP
(0x4310)
Programmable fault: 31.01
Mot temp1 prot
Estimated motor
temperature (based on
motor thermal model) has
exceeded fault limit defined
by parameter 31.04 Mot
temp1 fltLim.
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 31.09…31.14).
Measured motor
temperature has exceeded
fault limit defined by
parameter 31.04 Mot temp1
fltLim.
Check that actual number of sensors
corresponds to value set by parameter
31.02 Mot temp1 src.
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.
0049 AI SUPERVISION
(0x8110)
Programmable fault: 13.32 AI
superv func
An analog input has
reached limit defined by
parameter 13.33 AI superv
cw.
Check analog input source and
connections.
Check analog input minimum and
maximum limit settings.
0055 TECH LIB
(0x6382)
Resettable fault generated
by a technology library.
Refer to the documentation of the
technology library.
