Technical advantage

1, Using the newest DSP system control, can realize quick real-time control and strong expandability, and realize new breakthrough for vector control hardware control platform, it is the best choice of high reliability control occasion. 

2, Leads magnetic field orientation vector control arithmetic successfully finish motor entirely decoupling control, realize real current vector control, make the system easy to control, perceptible improve dynamic and static performance of the system. 

3, Collect three high performance speed control types including non PG vector control(SVC), torque control(TC) and V/F control, fully meet the application occasions that ask high standards to speed control precise, torque response speed, and meet customers'different application demands. 

4, Motor parameters auto-identification arithmetic, can identify automatically motor electric parameters, lay the foundation of high performance vector control. 

5, Superior torque control performance, can meet customers'precise torque control demand.
