8. What is the difference between U/F control and vector control?

A detailed comparison of the various advantages and disadvantages of the frequency converter control variants is very comprehensive, so we would only like to point out one conclusion here:

In summary, U/f control and vector control show different strategies for motor control. V/f control maintains a fixed voltage-frequency ratio, while vector control introduces phase control to improve transient performance. Both systems have their advantages and the choice depends on the requirements of the application. LS frequency converters are generally preset to vector operation. The U/F control variant can be easily changed in the frequency converter menu.
