With speed sensor vector control
(FVC)
0: VF control
VF control is suitable for low-speed occasions where the control accuracy is not high, and can also be used for
occasions where one inverter drives multiple motors. It is recommended to set P1-00 ~ P1-05 in VF control.
1: No speed sensor vector control (SVC)
It refers to the open-loop vector control, which can be applied to high-performance general occasions without
pulse encoder, occasions requiring low-frequency large torque and high speed control accuracy, such as
machine tools, centrifuges, wire drawing machines, injection molding machines, etc.
2: With speed sensor vector control (FVC)
It refers to closed-loop vector control. The motor end must be equipped with encoder, and the frequency
converter must be equipped with PG card of the same type as the encoder. Suitable for high precision speed
control or torque control occasions, such as high-speed paper machinery, lifting machinery, elevators and other
loads.
For vector control of frequency converter, only one motor can be driven by one frequency converter, so accurate
parameters of controlled motor must be obtained for self tuning. See P1-35 for specific tuning method.
