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 location for drive has
ceased communicating.
Motor is operating in stall region
because of e.g. excessive load or
insufficient motor power.
Brake resistor broken or not
connected.
Brake resistor temperature has
exceeded fault limit defined by
parameter 43.11 Brake resistor fault
limit.
Brake resistor short circuit or brake
chopper control fault.
Short circuit in brake chopper IGBT.

What to do
Contact your local ABB
representative.
Check the settings in parameter
group 58 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.
Check motor load and drive ratings.
Check fault function parameters.
Check that a brake resistor has been
connected.
Check the condition of the brake
resistor. Check the dimensioning of
the brake resistor.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameter group
43 Brake chopper).
Check fault limit setting, parameter
43.11 Brake resistor fault limit.
Check that braking cycle meets
allowed limits.
Check brake chopper and brake
resistor connection.
Ensure brake resistor is not
damaged.
Ensure brake resistor is connected
and not damaged.
Check the electrical specifications of
the brake resistor against chapter
Resistor braking in the Hardware
manual of the drive.
Replace brake chopper (if
replaceable).
