Set this parameter to a value as small as possible in the prerequisite of efficient oscillation suppression to
avoid influence on VF control.
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.
When the oscillation suppression function is enabled, the rated motor current and no-load current must be
correct. Otherwise, the VF oscillation suppression effect will not be satisfactory.

100.0% corresponds to the rated motor voltage (P1-02, A2-02, A3-02,
A4-02)
VF separation is generally applicable to scenarios such as induction heating, inverse power supply and motor
torque control.
If VF separated control is enabled, the output voltage can be set in P3-14 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 (P3-14)
The output voltage is set directly in P3-14.
1: VS 2: AS
3: VS2
The output voltage is set by VS terminals.
4: PULSE setting (X5)
The output voltage is set by pulses of the terminal X5.
