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.
