Provide 0.5Hz 150% rated torque, easy to start the spindle motor;

With excellent speed control accuracy, the control accuracy is 0.2%, and accurate speed control is achieved;

With good field weakening control, it can achieve precise control even when running at high frequency;

It has the advantage of fast torque response, and when the load fluctuates, the current fluctuation is small;

It has good overload capacity and environmental adaptability, and has high operational reliability; 

Superior AVR function, super grid adaptability, guarantee output voltage, current and speed stability;

Excellent current limiting characteristics, strong overload capacity, can effectively reduce frequency conversion overload, over-current protection, maximum limit to ensure production continuity;

It has strong environmental adaptability, and the completely independent air duct design can greatly improve the resistance to harsh environments such as oil pollution, dust and damp heat.
