Fault tracing 385
A7C1
FBA A communication
Programmable warning:
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
,
,
and
Check cable connections.
Check if communication master is able to
communicate.
A7CE EFB comm loss
Programmable warning:
Communication break in
embedded fieldbus (EFB)
communication.
Check the status of the fieldbus master
(online/offline/error etc.).
Check cable connections to the
EIA-485/X5 terminals 29, 30 and 31 on
the control unit.
A7EE Panel loss
Programmable warning:
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.
Check mounting platform if being used.
Disconnect and reconnect the control
panel.
A8A0
AI supervision
Programmable warning:
An analog signal is outside the
limits specified for the analog
input.
Check signal level at the analog input.
Check the wiring connected to the input.
Check the minimum and maximum limits
of the input in parameter group
A8A1
RO life warning
The relay has changed states
more than the recommended
number of times.
Change the control board or stop using
the relay output.
0001 Relay output 1
Change the control board or stop using
relay output 1.
0002 Relay output 2
Change the control board or stop using
relay output 2.
0003 Relay output 3
Change the control board or stop using
relay output 3.
A8A2
RO toggle warning
The relay output is changing
states faster than
recommended, eg. if a fast
changing frequency signal is
connected to it. The relay
lifetime will be exceeded
shortly.
Replace the signal connected to the relay
output source with a less frequently
changing signal.
