Control system: based on the DSP high-performance vector control
Way of control : V/F control, open-loop magnetic flux vector control , PG vector control
Description:
1. Using DSP as the core of control unit to achieve high-speed high-performance control;
2. Way of speed control: SVC, VC, V/F control, torque control;
3. Automatically idendtify the motor parameters, intelligent adjustment to the best control mode;
4. Deard time compensation and automatic slip compensation function, low frequency 0.25HZ can be
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.
