 VF full separation
The output voltage and output frequency are completely independent. The output frequency is determined by the
frequency source. The output voltage is determined by P12.20. Suitable for applications such as variable
frequency power or torque motors.
 VF semi-isolated
At this point the ratio of output voltage and output frequency given by the voltage source, the formula is as
follows:：
