Note: The
value of
100.0%
corresponds
to the rated
motor voltage.
This parameter is used to set the target
voltage in the voltage and frequency
separation mode.
0: Digital setting (F3‑14)
F3‑14 (voltage digital setting for V/f
separation) can be used to set the V/f
separation voltage.
1: AI1
The V/f separation voltage is input through
AI1 by current or voltage signal. The
frequency is calculated according to the set
AI curve.
2: AI2
The V/f separation voltage is input through
AI2 by current or voltage signal. The
frequency is calculated according to the set
AI curve.
3: AI3
The V/f separation voltage is input through
AI3 by current or voltage signal. The
frequency is calculated according to the set
AI curve.

The V/f separation voltage is set through
DI5. The frequency is calculated based on
the curve of relationship between the pulse
frequency and running frequency.
5: Multi‑reference
When multi‑reference is configured as the
source for V/f separation voltage, setpoints
can be configured by grouping different DI
states. The four multi‑reference terminals
can provide 16 state combinations,
corresponding to 16 reference values
(percentage x maximum frequency) of
parameters in group FC.
