Freq level check (FDT)
When inverter output freq is higher than FDT freq level, output valid signal (lower electrical level)
by setting delay time. When inverter output freq is lower than FDT freq level, output invalid
signal (high-resistance) by same delay time.

Overload checkout
When inverter output current is higher than overload warning level, output valid signal (lower
electrical level) by setting warning delay time. When inverter output current is lower than
overload warning level, output invalid signal (high-resistance) by same delay time.

：
Freq reaches upper limit
When inverter output freq reaches upper freq, this terminal outputs valid signal (lower electrical
level), otherwise, outputs invalid signal (high-resistance).
5
：
Freq falls to lower limit
When inverter output freq falls to lower freq, this terminal outputs valid signal (lower
electrical level), otherwise, outputs invalid signal (high-resistance).
