Cause
Embedded fieldbus (EFB)
configuration file could not be
read.
Embedded fieldbus (EFB)
parameter settings
inconsistent or not compatible
with selected protocol.
Embedded fieldbus (EFB)
protocol firmware could not be
loaded.
Version mismatch between
EFB protocol firmware and
drive firmware.
Fault reserved for the EFB
protocol application.
Fault reserved for the EFB
protocol application.
Internal fault.
Internal fault.
Control panel or PC tool
selected as active control
49.05
location for drive has ceased
communicating.
Fieldbus option module not
supported.
Motor is operating in stall
region because of e.g.
31.24
excessive load or insufficient
motor power.
Brake resistor temperature has
exceeded fault limit defined by
parameter 43.11 Brake resistor
fault limit.
Brake chopper IGBT
temperature has exceeded
internal fault limit.

What to do
Contact your local ABB representative.
Check the settings in parameter group
Embedded fieldbus.
Contact your local ABB representative.
Check the documentation of the protocol.
Check the documentation of the protocol.
Reset the fault. Contact your local ABB
representative if the fault persists.
Reset the fault. Contact your local ABB
representative if the fault persists.
Check PC tool or control panel
connection.
Check control panel connector.
Disconnect and reconnect the control
panel.
Replace the module with a supported
type.
Check motor load and drive ratings.
Check fault function parameters.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameter group
Brake chopper).
Check fault limit setting, parameter
Brake resistor fault limit.
Check that braking cycle meets allowed
limits.
Let chopper cool down.
Check for excessive ambient
temperature.
Check for cooling fan failure.
Check for obstructions in the air flow.
Check resistor overload protection
function settings (parameter group
Brake chopper).
Check that braking cycle meets allowed
limits.
Check that drive supply AC voltage is not
excessive.
