Hardware Fault
Something is wrong with
FlashProm or thyristor diagnosis
has detected a short circuit.

F 3 Software Fault
Software Fault
There may be an internal error in
software.
If this fault occurs please read
out Parameter 7.03 Diagnosis
and 7.04 SW Version from the
control panel for use to contact
ABB local service center.

F 4 Par Flash Read Fault
Parameters Flash Read Fault
While booting up the soft-
ware.The parameter checksum
in the Flash is incorrect.
A possible problem cause is that
the power supply was switched
off during storage of parameters.
In this case all parameters are
set back to their default values.
If you have uploaded the para-
meters for your application to the
control panel before, please
download them to the drive
again. Otherwise you have to set
all parameters again.

F 5 Compatibility Fault
Compatibility Fault
Software or Typecode was
changed to a version that is not
compatible with the parameters
which have been stored in the
Flash memory of the drive (e.g.
min/max check).
Some parameters may have
been set back to default value.
You can look up from parameter
7.03 Diagnosis the number of
the last of the concerned para-
meters.

F 6 Typecode Read Fault
Typecode Read Fault
The nominal data of the conver-
ter was found incorrect during
boot up (checksum error).
FlashProm broken or power
supply shut down during ’Set
Typecode’ function. Try to cor-
rect the Typecode again.

6.4.5 Fault Signals (F)
The fault signals will be shown on the seven segment display of the
control board SDCS-CON-3A as codes F . . as well as on the LCD
of the control panel DCS 400 PAN as plain text.
All fault signals - with the exception of F1 to F6 - can be reset by
Panel Reset-button or by external Signal at X4:6 (after elimina-
tion of the fault cause).
Fault signal F1 to F6 can be only reset by switching electronics
supply OFF and ON.
Note: „F1“ , „Fault 1“ and „F01“ are equivalent
For resetting (RESET) of fault signals the following steps are
required:
• Switching off the commands ON/OFF and RUN
• Elimination of the fault causes
• Fault acknowledgement, i.e. resetting (RESET)
a) press „RESET“ key on DCS400PAN
or b) by setting of the RESET digital input (DI6)
for at least 100ms to high (logical 1)
or c) if a Fieldbus is selected by setting the „RESET“ bit
in the Main Control Word to „high“ for at least
100ms.
• Depending on the application conditions generate the
commands ON/OFF and RUN once more.
All faults will switch off the signal
energizing the main contac-
tor.
