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
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:
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:
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
.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameter group
).
Check fault limit setting, parameter
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).
