How to choose the speed control mode of general inverter: general inverter is also called high-performance inverter, PG-free vector inverter, torque control inverter, why? It turns out that the speed control mode is different, so how to choose the speed control mode of the inverter? The following is a brief introduction to the hard power editor
The first type: vector control without speed sensor
High-Performance General Vector Inverter Refers to open-loop vector control, which is suitable for general high-performance control occasions. One inverter can only drive one motor. Such as machine tools, centrifuges, wire drawing machines, injection molding machines and other loads. When setting the inverter function code (that is, setting F0.01), select the setting range value: 0.
The second type: vector control with speed sensor
Refers to closed-loop vector control. An encoder must be installed at the motor end, and the inverter must be equipped with a PG card of the same type as the encoder. It is suitable for high-precision speed control or torque control occasions. One inverter can only drive one motor. Such as high-speed papermaking machinery, hoisting machinery, elevators and other loads. When setting the inverter function code (that is, setting F0.01), select the setting range value: 1.
The third type: V/F control
It is suitable for occasions where the load requirements are not high, or one inverter drives multiple motors, such as fans and pumps. It can be used in occasions where one inverter drives multiple motors. When setting the inverter function code (that is, setting F0.01), select the setting range value: 2.
Warm reminder: The motor parameter tuning process must be carried out when selecting the vector control mode. Only accurate motor parameters can give full play to the advantages of vector control.
