Check PC tool or control panel
connection.
Control panel (or PC tool) has stopped
communicating.

Check control panel connector.
Disconnect and reconnect the control
panel.
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 569).
The I/O extension module types specified
by parameters do not match the detected
configuration.

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.

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.

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

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 stall7121
Check fault function parameters.
Check for overloaded motor.Motor current is too high.Motor overload7122
Adjust the parameters used for the motor
overload function 35.51…35.53) and
35.55…35.56.
