7084 Panel/PC tool version
conflict
The current version of the
control panel and/or PC tool
does not support a function.
(For example, older panel
versions cannot be used as a
source of external reference.)
Update control panel and/or PC tool.
Contact your local ABB representative if
necessary.
7085 Incompatible option
module
Option module not supported.
(For example, type Fxxx-xx-M
fieldbus adapter modules are
not supported.)
Check the auxiliary code. The code
specifies the interface to which the
unsupported module is connected:
1: Fieldbus interface A, 2: Fieldbus
interface B.
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.
7122 Motor overload
Programmable fault: 35.56
Motor overload action
Motor current is too high. Check for overloaded motor.
Adjust the parameters used for the motor
overload function (35.51…35.53) and
35.55…35.56.
7181 Brake resistor DC overvoltage detected
during braking.
Check that a brake resistor has been
connected.
Check the condition of the brake resistor.
Check the dimensioning of the brake
chopper and 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.
After correcting the cause of the fault,
reboot the control unit (using parameter
96.08 Control board boot) or by cycling
power.
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 the Hardware
manual.
Replace brake chopper (if replaceable).
After correcting the cause of the fault,
reboot the control unit (using parameter
96.08 Control board boot) or by cycling
power.
