The selection method of this gain is to take as small amount as possible on the premise that the oscillation is
suppressed efficiently, so as to avoid negative effect on VF operation. The gain should be chosen 0 when
the electrical machine is free from oscillation. Only when the machine is subject to obvious oscillation, can
the gain be increased to a proper extent. The larger the gain is, the more apparent the oscillation
suppression.
To use the oscillation suppression function, accurate parameters of the related and non-load current of the
electrical machine is required, otherwise the VF oscillation suppression will not be effient enough

VF separation is generally apllied to induction-heating, inverter and torque motor control, etc.
To choose VF separation control, the output voltage can be set either through function code F3-14 or analog
quatity, multistage command, PLC, PID or communication. When doing non-numeric setting, 100%of each
setting should be correspondent with the nominal voltage of the electrical machine. When the percentage set
by analog quantity and other outputs is negative, then the absolute value of the setting should be considered
as the valid set value

The correspondence between the given signal and the given voltage should be determined by setting the
parameters of F4 and FC group if the voltage sourse is multistage command. The given 100.0% by
multistage command of FC group parameter refers to the percentage compared to the nominal voltage of the
