Faults

Number / Fault Cause
F001 If a main contactor checkback is configured,
no checkback occurs within the time set in
Main contactor P600 after the power-up command. In the
checkback case of externally excited synchronous motors
(P095 = 12), there is no checkback for the
excitation current unit.
F002 When pre-charging, the minimum DC link
voltage (P071 Line Volts x 1.34) of 80 % has
Pre-charging not been reached.
The maximum pre-charging time of 3 seconds
has been exceeded.
F006 Shutdown has occurred due to excessive DC
link voltage.
DC link overvoltage
Line voltage I DC voltage range I Shutdown
-------------------------------------------------------------
200 V - 230 V I 270 V - 310 V I appr. 410 V
380 V - 480 V I 510 V - 650 V I appr. 820 V
500 V - 600 V I 675 V - 810 V I appr. 1020 V
660 V - 690 V I 890 V - 930 V I appr. 1220 V
For parallel-connected converters (BF M,N)
r949 = 1: Overvoltage in the DC link of the
master
r949 = 2: Overvoltage in the DC link of the
slave.

General information regarding faults
For each fault, the following information is available:
Parameter r947
r949
r951
P952
r782
If a fault message is not reset before the electronic supply voltage is
switched off, then the fault message will be present again when the
electronic supply is switched on again. The unit cannot be operated
without resetting the fault message. (Exception: Automatic restart has
been selected, see P373).

P591 Src Contactor Msg
Parameter value must be in conformance with
the connection of the main contactor
checkback.
Check the checkback loop of the main
contactor (or the checkback of the excitation
current unit in the case of synchronous
motors).
Check the supply voltage,
Compare witth P071 Line Volts (Compare
P071 with the DC link voltage on DC units).
Check the rectifier/regenerative unit on DC
units. The rectifier/regenerative unit must be
switched on before the inverter is switched on.
Check the supply voltage or input DC voltage.
Converter is operating in regenerative mode
without feedback possibility.
value
If the converter supply voltage is at the upper
tolerance limit and it is operating at full load,
F006 can also be caused by a line phase
failure.
Possibly
- Increaase P464 Decel Time,
- Activate P515 DC Bus Volts Reg (check
P071 beforehand)
- Reduce P526 Fly Search Speed.
- Reduce P259 Max Regen Power (only for
P100 = 3, 4 or 5)
