This code displays up to five previous fault (trip) status of
the inverter. Use the PROG, ? 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 ENT
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 are WDOG error, EEP error, and ADC
Offset for the inverter Hardware Fault, and 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.
