The selection method of the gain is as small as possible under the premise of effectively suppressing the
oscillation, so as to avoid adversely affecting the V/f operation. Select this gain to be 0 when there is no oscillation
in the motor. It is only necessary to increase the gain appropriately when the motor oscillates significantly.The
greater the gain, the more obvious the suppression of the oscillation.
When using the suppression oscillation function, the motor rated current Motor rated current and no-load current
parameters are required to be accurate,otherwise the V/f oscillation suppression effect is not good.

V/f detach separation is generally used in applications such as induction heating, inverter power supply and
torque motor control.
If V/f separated control is selected, the output voltage can be set by parameter 03-14, or set communication can
be given by analog quantity, multi-step speed command, PLC, PID or communication. When a non-numeric
setting is selected, 100% of each setting corresponds to the rated voltage of the motor. When the percentage of
the output setting such as the analog quantity is negative, the set absolute value is used as the effective setting
value.
0.Digital setting (03-14)
Voltage is set by 03-14.
1.AVI1
2.AVI2/ACI
Voltage is confirmed by analog input terminal.
4.Pulse setting(MI5)
The voltage reference is given by the terminal pulse. Pulse given signal specifications: voltage range 20V ~ 27V,
frequency range 0kHz ~ 100kHz.
