Warning / Aux. code
Maximum continuous
power not given.
Brake chopper IGBT
temperature has
exceeded internal
warning limit.
Installed CMOD
module is not the same
as configured.
Cyclical communication
between drive and
fieldbus adapter
module A or between
PLC and fieldbus
adapter module A is
lost.
Communication break
in embedded fieldbus
(EFB) communication.
Control panel or PC
tool selected as active
control location for
drive has ceased
communicating.
Maintenance timer limit
exceeded.
Cause What to do
Check value of 43.09.
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).
Check minimum allowed resistor
value for the chopper being used.
Check that braking cycle meets
allowed limits.
Check that drive supply AC voltage is
not excessive.
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.
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.
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.
Check PC tool or control panel
connection.
Check control panel connector.
Check mounting platform if being
used.
Disconnect and reconnect the control
panel.
Consider changing the cooling fan.
Parameter 05.04 Fan on-time counter
shows the running time of the cooling
fan.
