    AC70 sensorless vector control frequency inverter is one of the most best-selling low voltage inverters of Veichi that it's famous for its great quality and stable performance. This sensorless vector control frequency drive is of compact structure design and made of durable components that it can meet various kinds of load challenges and application scenarios.

    1. Advanced control algorithm

    AC70 vector motor control drive is developed with the latest control algorithms such as V/F, vector control without PG and PID control (what is PID control?) that it can flexibly meet multiple complicated application requirements such as fast response speed, high precision speed control, variable speed control and more. 
    Without PG vector control, the torque response speed= 20ms, torque control precision ±1%, 150% rated torque under 1Hz.
    Efficiency Improving
