Cause
Cyclical communication
between drive and fieldbus
50.02
adapter module A or between
PLC and fieldbus adapter
module A is lost.
Cyclical communication
between drive and fieldbus
50.32
adapter module B or between
PLC and fieldbus adapter
module B is lost.
DDCS (fiber optic)
communication between
60.79
converters (for example, the
inverter unit and the supply
unit) is lost.
DDCS (fiber optic)
communication between drive
and external controller is lost.
60.59
Master/follower
communication is lost.
60.09
The supply unit (or other
converter) connected to the
inverter unit has generated a
fault.
The supply unit was not ready
(ie. the main contactor/breaker
could not be closed) within
expected time.
Selected signal has fallen
below the user underload
curve.
Fault tracing 601
What to do
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter groups
Fieldbus adapter (FBA),
settings, 52 FBA A data in
data out.
Check cable connections.
Check if communication master is able to
communicate.
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter group
Fieldbus adapter (FBA).
Check cable connections.
Check if communication master is able to
communicate.
Check status of other converter
(parameter group 06 Control and status
words).
Check settings of parameter group
DDCS communication. Check the
corresponding settings in the control
program of the other converter.
Check cable connections. If necessary,
replace cables.
Check status of controller. See user
documentation of controller.
Check settings of parameter group
DDCS communication.
Check cable connections. If necessary,
replace cables.
See A7CB MF comm loss
The auxiliary code specifies the original
fault code in the supply unit control
program. Refer to the firmware manual of
the supply unit.
Check that communication to the supply
unit has been activated by
options word 1.
Check setting of parameter
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).
See A8BF ULC underload warning
584).
