Cause
What to do
6682
EFB config file
Embedded fieldbus (EFB)
configuration file could not be read.
Contact your local ABB
representative.
6683
EFB invalid parameterization
Embedded fieldbus (EFB) parameter
settings inconsistent or not
compatible with selected protocol.
Check the settings in parameter
group
58 Embedded fieldbus
.
6684
EFB load fault
Embedded fieldbus (EFB) protocol
firmware could not be loaded.
Contact your local ABB
representative.
Version mismatch between EFB
protocol firmware and drive
firmware.
6685
EFB fault 2
Fault reserved for the EFB protocol
application.
Check the documentation of the
protocol.
6686
EFB fault 3
Fault reserved for the EFB protocol
application.
Check the documentation of the
protocol.
6882
Text 32-bit table overflow
Internal fault.
Reset the fault. Contact your local
ABB representative if the fault
persists.
6885
Text file overflow
Internal fault.
Reset the fault. Contact your local
ABB representative if the fault
persists.
7081
Control panel loss Programmable
fault:
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.
Disconnect and reconnect the control
panel.
7121
Motor stall Programmable fault:
31.24 Stall function
Motor is operating in stall region
because of e.g. excessive load or
insufficient motor power.
Check motor load and drive ratings.
Check fault function parameters.
7181
Brake resistor
Brake resistor broken or not
connected.
Check that a brake resistor has been
connected.
Check the condition of the brake
resistor. Check the dimensioning of
the brake resistor.
7183
BR excess temperature
Brake resistor temperature has
exceeded fault limit defined by
parameter
43.11 Brake resistor fault
limit
.
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.
7184
Brake resistor wiring
Brake resistor short circuit or brake
chopper control fault.
Check brake chopper and brake
resistor connection.
Ensure brake resistor is not
damaged.
7191
BC short circuit
Short circuit in brake chopper IGBT.
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).
