Faults

Number / Fault
Cause
F001
The monitoring time of the main contactor
checkback (P600) has expired.
Main contactor
checkback
F002
The monitoring time of pre-charging has
expired, i.e. the DC link voltage has not
Pre-charging fault
reached the setpoint within 3 secs.
F006
Due to excessive DC link voltage, shutdown
has occurred (shutdown threshold approx.
DC link overvoltage
820 V)
F008
The lower limit value of 76% of the DC link
voltage has been fallen short of.
DC link undervoltage
F011
Overcurrent shutdown has occurred.
The shutdown threshold has been exceeded.
Overcurrent
The phase in which an overcurrent has
occurred is indicated in a bit-coded manner in
the fault value (see P949).
Phase U --> Bit 0 = 1--> fault value = 1
Phase V --> Bit 1 = 1--> fault value = 2
Phase W--> Bit 2 = 1--> fault value = 4
If an overcurrent occurs simultaneously in
several phases, the total of the fault values of
the phases concerned is the resulting fault
value.

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).

Counter-measure
- Check main contactor checkback
- Clear main contactor checkback (P591.B =
0)
- Increase monitoring time (P600)
- Check voltage connection (AC or DC)
- Compare value in P070 and unit MLFB
Check the line voltage (AC-AC) or the input
direct voltage (DC-AC). Compare value with
P071 (Line Volts)
- check the line voltage (AC-AC) or the input
direct voltage (DC-AC). Compare value with
P071 (Line Volts)
- check input rectifier (AC-AC)
- check DC link
- Check the converter output for short-circuit or
earth fault
- Check the load for an overload condition
- Check whether motor and converter are
correctly matched
- Check whether the dynamic requirements
are too high
