0: Digital setting (non‑retentive upon power failure)
The initial value of the frequency is the value of F0‑08 (Preset
frequency). The frequency can be changed by using the ▲ and
▼ keys on the operating panel or the multi‑functional input
terminal functioning as the UP and DOWN key. When the AC
drive is powered on again after a power failure, the frequency
reference is restored to the value of F0‑08.
1: Digital setting (retentive upon power failure)
The initial value of the frequency is the value of F0‑08 (Preset
frequency). The frequency can be changed by using the ▲ and
▼ keys on the operating panel or the multi‑functional input
terminal functioning as the UP and DOWN key. When the AC
drive is powered on again after a power failure, the frequency
reference is the same as that at the moment of the last power
failure. Modifications made by using keys ▲ and ▼ keys on the
operating panel or the multi‑functional input terminal
functioning as the UP and DOWN key remain effective.
2: AI1
The frequency reference is calculated based on current or
voltage signals input through AI1 and the preset AI curve.
3: AI2
The frequency reference is calculated based on current or
voltage signals input through AI2 and the preset AI curve.
4: AI3
The frequency reference is calculated based on current or
voltage signals input through AI3 and the preset AI curve.
5: Pulse reference (DI5)
The frequency reference is set by using the pulse frequency
input through DI5. The frequency is calculated according to the
relationship curve between the pulse frequency and the
frequency reference.
6: Multi‑reference
In the multi‑reference mode, combinations of different DI states
correspond to different frequency reference. The four multi‑
reference terminals can provide 16 state, corresponding to 16
reference values.
