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.
7085 Incompatible option
module
Fieldbus option module not
supported.
Replace the module with a supported
type.
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.
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.
7192 BC IGBT excess
temperature
Brake chopper IGBT
temperature has exceeded
internal fault limit.
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 43
Brake chopper).
Check that braking cycle meets allowed
limits.
Check that drive supply AC voltage is not
excessive.
