Cause
Encoder 1 feedback fault
Encoder 2 feedback fault.
Cyclical communication
between drive and fieldbus
adapter module or between
PLC and fieldbus adapter
module is lost.
Drive internal fault
Estimated motor temperature
(based on motor thermal
model) has exceeded fault limit
defined by parameter 31.04
Mot temp1 fltLim.
Measured motor temperature
has exceeded fault limit
defined by parameter 31.04
Mot temp1 fltLim.
An analogue input has reached
limit defined by parameter
13.33 AI superv cw.
What to do
If fault appears during first start-up before
encoder feedback is used:
- Check cable between encoder and
encoder interface module (FEN-xx) and
order of connector signal wires at both
ends of cable.
If fault appears after encoder feedback
has already been used or during drive
run:
- Check that encoder connection wiring
or encoder is not damaged.
- Check that encoder interface module
(FEN-xx) connection or module is not
damaged.
- Check earthings (when disturbances
are detected in communication between
encoder interface module and encoder).
For more information on encoders, see
parameter groups 90 Enc module
Resolver conf and 93 Pulse enc
See fault 0039.
Check status of fieldbus communication.
See appropriate User's Manual of
fieldbus adapter module.
Check settings of parameter group
Fieldbus.
Check cable connections.
Check if communication master is able to
communicate.
Contact your local ABB representative.
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).
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.
Check analogue input source and
connections.
Check analogue input minimum and
maximum limit settings.
