number.
FU2-01: Previous Fault History 1
FU2-02: Previous Fault History 2
FU2-03: Previous Fault History 3
FU2-04: Previous Fault History 4
FU2-05: Previous Fault History 5
FU2-06: Erase Fault History
This code displays up to five previous fault (trip)
status of the inverter. Use the [FUNC], [
▲] and [▼]
key before pressing the [RESET] key to check the
fault content(s), output frequency, output current,
and whether the inverter was accelerating,
decelerating, or in constant speed at the time of
the fault occurred. Press the [FUNC] key to exit.
The fault content will be stored in FU2-01 through
FU2-05 when the [RESET] key is pressed. For
more detail, please refer to Chapter 7.

Note: There is Fan error, EEP error, CPU2 error, Ground fault
and NTC error for the inverter Hardware Fault. The inverter
will not reset when H/W fault occurs. Repair the fault before
turning on the power.
☞ Note: When multiple faults occur, only the highest-level fault
will be displayed.
This function erases all fault histories of FU2-01 to
FU-05 from the memory.
FU2-07: Dwell Frequency
FU2-08: Dwell Time
This function is used to output torque in an
intended direction. It is useful in hoisting
applications to get enough torque before a
