Fault and Alarm Messages
Fault
Fault description
No.
F001
Feedb Cont.
No checkback signal from main contactor
If a main contactor checkback signal is
configured and is not received within 500
ms after the power-up command.
F003
Line Over V
Network overvoltage of the infeed supply
Voltage at the terminals X1-U1/L1, and
X1-W1/L3 are greater than the response
threshold (120% of P071).
F004
Line Under V
Line undervoltage
Voltage at terminals X1-U1/L1, or X1-
W1/L3 and/or X4-1U2/1T1, X4-1V2/1T2 or
X4-1W2/1T3 lower than the response
threshold (P074 and P071).
F005
Line Frequ.
Line frequency outside permissible range
This fault message is generated if the line
frequency is lower than 45 Hz or higher
than 65Hz (or greater than 68.665Hz on
Software Version 4.4 and higher).
F006
Bus Over V
DC link voltage
The unit was shutdown due to an
excessive DC link voltage.
Line voltage-
range
380 V to 460 V
500 V to 575 V
660 V to 690 V
F007
AuxPowerOFF
Failure or overvoltage of the electronics
supply voltage in "Run" status
or
at least one power section connected in
parallel reports "Power supply faulted"
F009
Rec PhaseFlt
Phase failure in the rectifier bridge
The rms line voltage calculated from the
area of each line voltage half-wave
(average rectification value * peak value)
must be greater than the response value
for phase-failure monitoring
The interval between two identical line
voltage zeros of the voltage for the infeed
converter must not be greater than 450
deg.

-
Electronics supply voltage of the
rectifier/regenerating unit too low
Power interface module of the
rectifier/regenerating unit or parallel
power section reports "Power
supply faulted"
Voltage failure in the rectifier bridge
(X1-U1/L1, X1-V1/L2 or X1-W1/L3)

Possible causes
Countermeasures
- Check P591 Q.HS checkback
signal.
The parameter value must match
the main contactor checkback
signal connection
- Check the main contactor
checkback signal circuit.
- Line overvoltage
- P071 set to wrong value
- Line undervoltage
- Monitoring too finely or wrongly
set (P074, P071)
-Line frequency < 45Hz or > 65Hz
-
- Check electronics power supply
- Power supply fuse for parallel
units blown
- Internal fault on the power
interface module of a slave unit
- Parameter P074 wrongly set
- Phase failure in the rectifier
bridge
- Line contactor dropped out in
operation
- Fuse blown on three-phase side
of rectifier bridge
