0000 0003 Maximum continuous
power not given.
Check value of 43.09.
A79C BC IGBT excess
temperature
Brake chopper IGBT
temperature has
exceeded internal
warning limit.
Let chopper cool down.
Check for excessive ambient
temperature.
Check for cooling fan failure.
Check for obstructions in the air flow.
Check the dimensioning and cooling
of the cabinet.
Check resistor overload protection
function settings (parameters
43.06…43.10).

configuration failure
Installed CMOD
module is not the same
as configured.
Check that the installed module
(shown by parameter 15.02 Detected
extension module) is the same as
selected by parameter 15.01
Extension module type.
A7C1 FBA A communication
Programmable warning:
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.

Programmable warning:
58.14 Communication loss
action
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:
49.05 Communication loss
action
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.
