Parameter description
VF oscillation suppression gain
P3-11
Setting range
The gain selection method is effective in suppressing oscillation, try to take small, so as not to
adversely affect the VF operation. When the motor has no oscillation, select this gain as 0. Only when
the motor has obvious oscillation only be appropriate to increase the gain, the greater the gain, the
oscillation suppression result.
When using the oscillation suppression function requires the motor rated current and no-load
current parameters to be accurate, or VF oscillation suppressing effect is not good.

Setting range
VF separation generally used in induction heating, power inverter and torque motor control applications.
When choosing VF separation control, the output voltage can be set by function code P3-14, but also from
analog, multi-instruction, PLC, PID or communication given. When set to a non-digital, each set
corresponding to 100% of rated voltage of the motor, when the percentage of the absolute value of the
analog output setting, etc. is negative. So places is set as an active setpoint.
0: Digital setting (P3-14) voltage is directly set by P3-14.

Voltage from the analog input terminal to determine.
4. Pulse setup (DI5) given via the terminal voltage pulse given. Pulse reference signal specification: voltage
range 9V ~ 30V, frequency range 0kHz ~ 100kHz.
5. When multi-source voltage instruction multistage instruction, set the group P4 PC and set parameters to
determine if a given signal and the reference voltage correspondence.
6. Simple PLC
When the voltage source is simple PLC, need to set the PC set of parameters to determine if a given output
voltage.
7. PID
According PID closed loop generates an output voltage. See details PA group PID introduction.
8. Communication refers to the voltage given by the host computer via the communication mode. When the
voltage source selection 1-8, 0 corresponds to 100% of the output voltage of 0V ~ motor rated voltage.
