10.1.2 List of fault messages

NOTE
Further information about the causes of fault messages
When a fault message is activated, values providing more information about the fault cause are
stored in parameter r047. Where the values can be interpreted by the user, they are included in
the following list of fault messages.
The value in r047.001 is referred to as the "fault value". This is also stored in r949 which also
contains the fault values belonging to older fault messages. The values in r047 are overwritten
when the next fault message occurs.
Values for r047 which are not included in the list below can help a SIEMENS specialist to locate a
fault cause. For this reason, all indices of parameter r047 should be read out whenever a fault
message occurs, even if the meaning of the individual indices of parameter r047 is not specified
for every fault message listed below.
Please note: Before you contact SIEMENS with any query regarding a fault message, please
make a note of the contents of all indices of parameter r047.

10.1.2.1 Supply faults
F001 Failure of electronics power supply
(active in all operating states)
Failure of the electronics supply voltage (terminals 5U1, 5W1, 5N1) in "RUN" state for longer than the "restart" time set in
parameter P086 or the electronics are operating on undervoltage.
Possible fault causes:
•
Line contactor has opened in "RUN" state
•
Brief supply failure
•
Supply voltage too low
Fault value:
1 Electronics supply voltage in "RUN" has been interrupted
for longer than setting in P086
2 Supply failure prewarning responds periodically
3 Supply failure prewarning is active for longer than 1.28 s
F004 Phase failure in armature supply
(active in operating states of ≤ o4)
The supply voltage RMS value, calculated from the area of each supply half-wave (rectified average value * peak factor), must
be greater than the response value for phase failure monitoring
P078.001 ∗
The distance between two identical supply zero passages of a phase must not exceed 450 degrees.
If one of these two conditions remains unfulfilled for longer than the "restart time" set in P086, a fault message is activated.
After switch-on, the converter waits in operating states o4 and o5 together for a period not exceeding the setting in P089 for
voltage to appear at the power terminals (and for field current) before activating the fault message.
Possible fault causes:
•
Parameter P353 is incorrectly set
•
Armature phase has failed
•
Line contactor opened in operation
•
Fuse has blown on three-phase side in armature circuit
•
Fuse has blown in power section
•
Interruption in a thyristor firing pulse cable (auxiliary cathodes at connectors X12, X14, X16 are voltage carriers).
