SD780
1. Mini design with PIM integrative module(Voltage 380V) and IPM Intelligent Power Module(Voltage 220V)
2. Output 200% rated torque when frequency 1.5Hz
3. Flexible PWM Technology, electromagnetic noise of motor and electromagnetic radiation can be reduced to 70%,if compare with traditional PWM Technology
4. Intelligent regulator technology can fast control voltage and current of generatrix when accelerate, constant velocity and decelerate,can Implement excellent accelerate and decelerate characteristics,at the same time inverter can avoid useless trip.
5. New automatic Torque boost technology,use simple flux control,can Implement excellent Torque control better than common V/F control
6. Automatic current limiting function,automatic limit current in run-time, avoid frequently over current trip
