Chapter 4 Explanation of Functions

(1) Signal output when the constant-speed frequency is reached (01: FA1)

The inverter outputs the signal when the output frequency reaches the frequency specified by a frequency setting (F001, A020, A220, or A320) or multispeed setting (A021 to A035).

(Example)

Maximum frequency (fmax) = 120 Hz Set frequency (fset) = 60 Hz

fon = 120 x 0.01 = 1.2 (Hz) foff = 120 x 0.02 = 2.4 (Hz)

At acceleration, the signal turns on when the output frequency reaches 58.8 Hz (60 - 1.2 = 58.8).

At deceleration, the signal turns off when the output frequency reaches 57.6 Hz (60 - 2.4 = 57.6).

(2) Signal output when the set frequency is exceeded (02: FA2 or 24: FA4)

The inverter outputs the signal when the output frequency exceeds the acceleration or deceleration frequency specified by a frequency setting ("C042" or "C043" [FA2] or "C045" or "C046" [FA4]).

(3) Signal output only when the set frequency is reached (06: FA3 or 25: FA5)

The inverter outputs the signal only when the output frequency reaches the frequency specified by a frequency setting ("C042" or "C043" [FA3] or "C045" or "C046" [FA5]).
