Fault Description
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
Further information (r047.002 to r047.016)
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)
F005 Fault in the field circuit
(active in operating states of
o5)
The line voltage RMS value calculated from the area of each network half-wave (rectification average value
*
peak factor) must
be greater than the response value for phase failure monitoring
100%
P353
P078.002∗
The distance between two identical network zero passages of the voltage for the field converter must not exceed 450 degrees.
The actual field current K0265 equals < 50% of the required field current setpoint K0268 for more than 500ms. This monitoring
function is effective only if the field current setpoint corresponds to >2% of the converter rated field current.
If one of the fault conditions described persists in operation (or ≤ o4) for longer than the “restart” time set in P086, the fault
message is output.
After the converter is switched on, it waits in operating state o5 for a period not exceeding the setting in P089 for the field supply
voltage or sufficiently high field current before this fault message is activated.
As from Version 1.7, monitoring is achieved by timeout on field reduction or build-up after field reversal has been initiated.
Possible fault causes
• Threshold for phase failure (P353) set incorrectly
• Field phase failed
• Line contactor opened during operation
• Fuse blown in the field circuit
• Field current controller and/or field current precontrol not optimized or badly optimized (check P112, P253 to P256; possibly
execute current controller optimization)
• If the fault value is 6: Offset fault in the actual field current value sensing, relevant parameter: P825.i01-i03 (Offset depends
on P076.i02) or P394, P395 (Threshold and hysteresis for message I_field < I_field_min) must be checked
• If the fault value is 7: Circuit for the "new" field direction is interrupted (e.g. because the contactor for "new" field direction
does not pick up), P398, P399 (Threshold and hysteresis for message I_field < I_field_x) must be checked
Fault value:
1 Voltage failure occurred in the field supply (terminals 3U1 and 3W1) (if P086 = 0)
2 Delay time according to P089 elapsed in state o5.1 (waiting for voltage at the field power section)
3 Delay time according to P089 elapsed in state o5.0
(waiting until I
field act
(K0265) is > 50% of the instantaneous field current setpoint K0268)
4 After P086 > 0 has elapsed (time for automatic restart) in operating state ≤ o4:
Voltage failure in the field supply or
I
field act
(K0265) < 50% I
field set
(K0268) for longer than 500 ms
5 When P086 = 0 (no automatic restart) in operating state ≤ o4:
I
field act
(K0265) < 50% I
field set
(K0268) for longer than 500 ms
6 If field reduction before field reversal, I_field ≤ I_field_min (P394) is not reached within 30 s
7 If field build-up after field reversal, I_field > I_field_x (P398) is not reached within 30 s
