Cause
The I/O extension module types
specified by parameters do not match
the detected configuration.
Use of saved control panel reference
in multiple control modes attempted.
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.)
Option module not supported.
(For example, type Fxxx-xx-M fieldbus
adapter modules are not supported.)
Motor is operating in stall region
because of e.g. excessive load or
insufficient motor power.
Motor current is too high.
DC overvoltage detected during
braking.
Brake resistor temperature has
exceeded fault limit defined by
parameter 43.11 Brake resistor fault
limit.
What to do
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
The control panel reference can only
be saved for one reference type at a
time.
Consider the possibility of using a
copied reference instead of saved
reference (see the reference selection
parameter).
Update control panel and/or PC tool.
Contact your local ABB representative
if necessary.
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.
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.
Check fault function parameters.
Check for overloaded motor.
Adjust the parameters used for the
motor overload function 35.51...35.53)
and 35.55...35.56.
Check that a brake resistor has been
connected.
Check the condition of the brake
resistor.
Check the dimensioning of the brake
chopper and resistor.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameter group
43 Brake chopper).
Check fault limit setting, parameter
