Fault Fault description
No.
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..

F022 I t Overload
2
I t monitor of the power section has
responded
The monitor responds when 100 % of the
2
calculated I t value of the power section is
reached.
F023 LT-Temp.
Temperature of the power section too high
A check is made to see whether the heat
sink temperature measured using
thermistor(s) is > 95 °C (or 123,9°C)
Temperature of the power section too low
F029 Measure Flt
Fault in line voltage measurement
An offset > 5% has been detected when
attempting to compensate for the offset of
the line voltage measurement
F030 DC Bus Short
DC link short-circuit
The monitor responds if the following
conditions obtain for longer than 0.5 sec:
- The current limit of the
rectifier/regenerating unit is reached
(this condition does not apply during
circuit identification or during DC link
forming)
- The rectifier or regenerative current is
greater than 10% of the rated DC
current (P075)
- The DC link voltage is less than 5% of
1.35*P071
F031 Fuse Blown
Fuse blown in a thyristor branch of the
rectifier/regenerating unit or of a parallel
power section.

Fault and Alarm Messages
Possible causes
Countermeasures
- 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
- Drive operated too long under
overload conditions
- Check to see whether the rated
current of the R/G unit is
adequate for the specific
application
- See also P785
- Heat sink (air inlets and outlets)
contaminated
- Heat sink temperature sensor not
connected to X31, X32 on A1681
and/or A1682 module ("slave
unit")
- Fan has no voltage
- Fan faulted
- Fan running in the wrong
direction
- Fan fuse (F3, F4) defective
NOTE:
- Measure inlet air ambient
temperature. If ϑ > 40 ºC, note
reduction curves. See Section
14.1.
With water-cooled units:
- Water inlet temperature too high,
cooling circuit interrupted or
cooling water pump faulty
- Heat sink temperature sensor not
connected to X30 module on
A1681 and/or A1682
- Fault in the voltage path on the
power interface module (A1681
and/or A1682 and/or A1685) or
on the electronic module (CUR)
- Short-circuit in the DC link
- Thyristor branch fuse faulted
