ABB ACS880-104

Fault tracing 601
7510 FBA A communication
Programmable fault: 50.02
FBA A comm loss func
Cyclical communication
between drive and fieldbus
adapter module A or between
PLC and fieldbus adapter
module A is lost.
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter groups 50
Fieldbus adapter (FBA), 51 FBA A
settings, 52 FBA A data in and 53 FBA A
data out.
Check cable connections.
Check if communication master is able to
communicate.
7520 FBA B communication
Programmable fault: 50.32
FBA B comm loss func
Cyclical communication
between drive and fieldbus
adapter module B or between
PLC and fieldbus adapter
module B is lost.
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter group 50
Fieldbus adapter (FBA).
Check cable connections.
Check if communication master is able to
communicate.
7580 INU-LSU comm loss
Programmable fault: 60.79
INU-LSU comm loss
function
DDCS (fiber optic)
communication between
converters (for example, the
inverter unit and the supply
unit) is lost.
Check status of other converter
(parameter group 06 Control and status
words).
Check settings of parameter group 60
DDCS communication. Check the
corresponding settings in the control
program of the other converter.
Check cable connections. If necessary,
replace cables.
7581 DDCS controller
comm loss
Programmable fault: 60.59
DDCS controller comm
loss function
DDCS (fiber optic)
communication between drive
and external controller is lost.
Check status of controller. See user
documentation of controller.
Check settings of parameter group 60
DDCS communication.
Check cable connections. If necessary,
replace cables.
7582 MF comm loss
Programmable fault: 60.09
M/F comm loss function
Master/follower
communication is lost.
See A7CB MF comm loss (page 581).
7583 Line side unit faulted The supply unit (or other
converter) connected to the
inverter unit has generated a
fault.
The auxiliary code specifies the original
fault code in the supply unit control
program. Refer to the firmware manual of
the supply unit.
7584 LSU charge failed The supply unit was not ready
(ie. the main contactor/breaker
could not be closed) within
expected time.
Check that communication to the supply
unit has been activated by 95.20 HW
options word 1.
Check setting of parameter 94.10 LSU
max charging time.
Check that the supply unit is enabled,
allowed to start, and can be controlled by
the inverter unit (eg. not in local control
mode).
8001 ULC underload fault
Programmable fault:
37.04 ULC underload
actions
Selected signal has fallen
below the user underload
curve.
See A8BF ULC underload warning (page
584).
