Set this parameter to 0 if the motor has no oscillation. Increase the value properly only
when the motor has obvious oscillation. The larger the value is, the better the oscillation
suppression result will be.

100.0% corresponds to the rated
motor voltage (F1-02, A2-02).
0
F3-14
Voltage digital setting
for V/F separation
0 V to rated motor voltage 0 V
V/F separation is generally applicable to scenarios such as induction heating, inverse power
supply and motor torque control.
If V/F separated control is enabled, the output voltage can be set in F3-14 or by means of
analog, multi-reference, simple PLC, PID or communication. If you set the output voltage by
means of non-digital setting, 100% of the setting corresponds to the rated motor voltage. If a
negative percentage is set, its absolute value is used as the effective value.
 0: Digital setting (F3-14)
The output voltage is set directly in F3-14.
 1: AI1; 2: AI2; 3: AI3
The output voltage is set by AI terminals.
 4: Pulse reference (DI5)
The output voltage is set by pulses of the terminal DI5.
