Set this parameter to a value as small as possible in the prerequisite of efficient oscillation suppression to avoid influence on V/F
control. Set this parameter to O if the motor has no oscillation. Increase the value properly only when the motor has obvious
oscillation. The larger the value is, the more obvious 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 V/F oscillation suppression effect will not be satisfactory.

V/F separation is generally applicable to the occasions, such as induction heating, inverse power supply and motor torque control.
If V/F separated control is enabled, the output voltage can be set by
function code P4.14 or by means of analog, multi-reference, simple PLC, PlD 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 (P4.14)
The output voltage is set directly by P4.14. 1: FIV; 2:FIC
The output voltage is set by Al terminals. 3: Reserved
4: Pulse setting (S3)
The output voltage is set by pulses of the terminal S3.
Pulse setting specification: voltage range 9-30 V, frequency range 0-100 kHz
5: Multi-reference
If the voltage source is multi-reference, parameters in group P4 and PC must be set to determine the corresponding relationship
between setting signal and setting voltage.
100.0% of the multi-reference setting in group FC corresponds to the rated motor voltage.
6: Simple PLC
If the voltage source is simple PLC mode, parameters in group FC must be set to determine the setting output voltage.
7: PID
The output voltage generates based on PID closed loop. For details, see the descriptions of PID in group PA.
8: Communication setting
The output voltage is set by the host computer by the means of communication given.
The voltage source for V/F separation is set in the same way as the frequency source.100.0% of the setting in each mode
corresponds to the rated motor voltage. If the corresponding value is negative, its absolute value is used.
