Diagnostics 67
6684 EFB load fault Embedded fieldbus (EFB) protocol
firmware could not be loaded.
Reload the firmware or replace the
unit. Contact ABB.
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
6882 Text 32-bit table
overflow
Internal fault. Reset fault. If fault persists, contact
ABB.
6885 Text file overflow Internal fault.
The table size is too short for
opening language file.
Reset the fault. If fault persists,
contact ABB.
7081 Control panel loss Control panel or PC tool ceased
communicating.
Check connections. 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 Motor is operating in stall region. Check motor load, drive ratings and
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 connections and brake resistor
dimensioning.
7183 BR excess
temperature
Brake resistor temperature has
exceeded the limit.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings and fault limit
settings. Check braking cycle limits.
7184 Brake resistor wiring Brake resistor short circuit or brake
chopper control fault.
Check connections.
7191 BC short circuit Short circuit in brake chopper IGBT. Check the electrical specifications.
Replace brake chopper.
7192 BC IGBT excess temp Brake chopper IGBT temperature
exceeded internal fault limit.
Let chopper cool down. Check
ambient temperature, cooling fan, air
flow, resistor overload protection
function settings, braking cycle limits
and supply voltage.
71A3 Mech brake opening
failed
Mechanical brake control is faulty.
Brake open acknowledgment is not
matching the actual status.
Check connections, brake settings
and brake acknowledgment signal.
73B0 Emergency ramp failed Emergency stop did not finish within
expected time.
Check predefined ramp times
(23.11…23.15 for mode Off1, 23.23
for mode Off3).
73F0 Overfrequency Maximum allowed output frequency
exceeded.
Check the auxiliary code.
00FA Motor is turning faster than the
highest allowed frequency due to
incorrectly set minimum/maximum
frequency or the motor rushes
because of too high supply voltage or
incorrect supply voltage selection in
parameter 95.01 Supply voltage.
Check minimum/maximum frequency
settings, parameters 30.13 Minimum
frequency
and 30.14 Maximum
frequency.
Check used supply voltage and
voltage selection parameter 95.01
Supply voltage.
Other - Contact your local ABB
representative, quoting the auxiliary
code.
