What to do Cause
Event name /
Aux. code Code
(hex)
Check the auxiliary code. The code
specifies the I/O port used as follows:
0: Panel, 1: Fieldbus interface A, 2:
Fieldbus interface B, 3: Ethernet, 4:
D2D/EFB port).
See A799 ExtIO comm loss (page 682) . The I/O extension module types
specified by parameters do not match
the detected configuration. Ext I/O comm
loss 7082
The control panel reference can only
be saved for one reference type at a
time. Use of saved control panel reference
in multiple control modes attempted. Panel
reference
conflict 7083
Consider the possibility of using a
copied reference instead of saved
reference (see the reference selection
parameter).
Update control panel and/or PC tool. The current version of the control
panel and/or PC tool does not support
a function. Panel/PC tool
version
conflict 7084
Contact your local ABB representative
if necessary.
(For example, older panel versions
cannot be used as a source of external
reference.)
Check the auxiliary code. The code
specifies the interface to which the
unsupported module is connected: Option module not supported.
(For example, type Fxxx-xx-M fieldbus
adapter modules are not supported.) Incompatible
option
module 7085
1: Fieldbus interface A, 2: Fieldbus
interface B.
Replace the module with a supported
type.
A - FSO-xx module is not supported by
the control board. Remove FSO-xx
module to clear the fault. Connect
FSO-xx module to the supported
control board.
Check motor load and drive ratings. Motor is operating in stall region
because of e.g. excessive load or
insufficient motor power. Motor stall 7121
Check fault function parameters.
Check for overloaded motor. Motor current is too high. Motor
overload 7122
Adjust the parameters used for the
motor overload function

and 35.55 … 35.56 .
Check that a brake resistor has been
connected. DC overvoltage detected during
braking. Brake resistor 7181
Check the condition of the brake
resistor.
Check the dimensioning of the brake
chopper and resistor.
Stop drive. Let resistor cool down. Brake resistor temperature has
exceeded fault limit defined by BR excess
temperature 7183
Check resistor overload protection
function settings (parameter group
43 Brake chopper ).
