Possible cause Notes
FEHLER_FU_TRIP, Washer. Fault in EFU 235. Fault
EFU fault, short registered from frequency
circuit converter control EFU. Short
circuit, total current in circuit >
47A for longer than 62.5 µs.
Impermissibly high drive motor
current.
FEHLER_FU_UEBE Fault registered from frequency
RSPANNUNG, converter control EFU 235.
EFU fault, excess Voltage in EFU 235 circuit is too
voltage high ( > 850VDC).
FEHLER_FU_UNTE Fault registered from frequency
RSPANNUNG, converter control EFU 235. EFU
EFU fault, low voltage 235 input voltage < 320V
Phase is missing. Fuse has
tripped.
FEHLER_FU_UEBE Washer. Fault registered from
RLASTUNG, frequency converter control
EFU fault, overload, EFU 235. EFU 235 circuit
too much power at power > 5kW for an
EFU impermissible period of time.
FEHLER_FU_NETZU Washer. Fault registered from
NTERBRECHUNG, frequency converter control
EFU fault, power EFU 235. Input voltage EFU
failure 235 is missing.
FEHLER_FU_OFFSE Washer. Fault registered from
T, EFU fault, current frequency converter control
sensors EFU 235. EFU 235 current
monitoring indicating
impermissible values. One or
more current sensors defective.
FEHLER_FU_UEBE Fault registered from frequency
RTEMPERATUR_IG converter control EFU 235. The
BT, EFU fault, excess temperature at the heat sink of
temperature at power the power output stage (IGBT)
output stage of the EFU 235 has exceeded
90°C (194°F).
FEHLER_FU_UEBE Fault registered from frequency
RSTROM, converter control EFU 235.
EFU fault, excess Peak motor current at M5 > 38A
drive motor current for time t > 1.5 s.
FEHLER_FU_TACH Fault registered from frequency
O, EFU fault, tacho converter control EFU 235.
signal Tacho impulse from
tachogenerator G1 is missing or
detected as faulty.
FEHLER_FU_ID, Fault registered from frequency
EFU fault, unknown converter control EFU 235. EFU
control ID control does not recognize the
software ID of the ELP 235.
FEHLER_FU_PARIT Fault registered from frequency
Y, EFU fault, converter control EFU 235. A
communication parity fault (a type of
fault between EFU transmission fault occurring with
and ELP data transmission) has occurred
during communication between
EFU 235 and ELP 235.
FEHLER_FU_OVER Fault registered from frequency
RUN, EFU fault, converter control EFU 235. An
communication fault overrun fault (a type of
between EFU and transmission fault occurring with
ELP data transmission) has occurred
during communication between
EFU 235 and ELP 235.
