achieved under sensorless vector control;

5. Simple PLC function can realize up to 16 segments speed and 4 segments acceleration control;

6. One key to shuttle keyboard, swirling free, two way custom button with the demand for expansion;

7. Multi-language, humanization display menu, highlighted OLED+LED simultaneous display 3 groups

of state parameters;

8. Keyboard is hot-pluggable and can store/copy 4 groups of operating parameter programs;

9. Powerful communications function which can support standard to support standard RS485 and

Modbus, meanwhile providing remote keyboard control;

10. Dual analog input, custom control mode, free combination of control factors;

11. Short-circuit protection, more safer and more stable;

12. New thermal management structure, unique duct design and thermostat heat agencies, allow the

product to run more stable and longer;

13. Standards EMC design to minimize pollution for power;

14. All strengthened PCB coating working well in kinds of environments.
