Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
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).
Fault value:
1 Voltage failure has occurred in armature supply (1U1, 1V1, 1W1) (when P086=0)
2 Delay time set in parameter P089 has expired in operating state o4
3 Fuse has blown in power section
4 Voltage failure has lasted longer than period set in P086 (if this is >0)
6 The "Main contactor checkback" (control word 2 bit 31) [see also P691] did not switch to "1" before the time set in P095 ran
out, or switched back to "0" during operation [V1.8 and later].
