Fault tracing 215
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.
7082 I/O module comm loss Communication between IO
module and drive is not
working properly.
Check installation of IO module.
7085 Incompatible option
module
Fieldbus option module not
supported.
Replace the module with a supported
type.
7086 I/O module AI
overvoltage
Overvoltage detected in AI. AI
is changed to voltage mode
from mA mode. AI will return
automatically back to mA
mode when the AI signal level
is within acceptable limits.
Check AI signal levels.
7100 Excitation current Excitation current feedback
low or missing
Contact your local ABB representative.
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.
7122 Motor overload Motor current is too high. Check for overloaded motor
Adjust the parameters used for the motor
overload function. (35.51…35.53,
35.55,35.56)
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.
