Meaning Possible causes
Countermeasures
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.
- - - Check P591 Q.HS checkback
signal.
The parameter value must match
the main contactor checkback
signal connection
- Check the main contactor
checkback signal circuit.
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).
- - - Line overvoltage
- P071 set to wrong value
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).
- - - Line undervoltage
- Monitoring too finely or wrongly
set (P074, 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- ⎢ Shutdown threshold

⎢
380 V to 460 V ⎢ 835 V
500 V to 575 V ⎢ 1042 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"
1, 2, 3
5
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"
- Check electronics power supply
- Power supply fuse for parallel
units blown
- Internal fault on the power
interface module of a slave unit
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.

Voltage failure in the rectifier bridge
(X1-U1/L1, X1-V1/L2 or X1-W1/L3)
Waiting time in status
o
010
elapsed
- 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
F010 Inv PhaseFlt
Phase failure in regenerative bridge
The rms line voltage calculated from the
area of each line voltage half-wave
(average rectification value x 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
regenerating converter must not be
greater than 450 deg..

Voltage failure in the regenerative
bridge (X4-1U2/1T1, X4-1V2/1T2
or X4-1W2/1T3)
Waiting time in status
o
010
elapsed
- 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
