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.
