General information regarding faults
For each fault, the following information is available:
Parameter r947 Fault number
r949 Fault value
r951 Fault list
P952 Number of faults
r782 Fault time
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).

Fault Counter-measure
F001 Main contactor checkback
If a main contactor checkback is configured,
no checkback takes place within the time set
in P600 after the power-up command.
In the case of externally excited synchronous
motors (P095 = 12), there is no checkback for
the excitation current unit.
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).
F002 Pre-charging
When pre-charging, the minimum DC link
voltage (P071 Line Volts × 1.34) of 80 % has
not been reached.
The maximum pre-charging time of 3
seconds has been exceeded.
Check the supply voltage,
Compare with 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.
