AS450 Vector Drives

AS450 drive is a vector drive. AS450 drive not only has the typical V / F control technology, but also uses the speed sensor free vector control technology, closed-loop vector control and torque control technology. These technologies further strengthen the product reliability, environmental adaptability, customization and industrial design, which can well meet the application requirements of various heavy-duty applications.

1. Open loop vector control and torque control technology;

2. Strong master-slave control function, suitable for flexible and rigid connection;

3. High speed lifting function, when light load or no load, the frequency converter can calculate the operation speed according to the size of the negative load, so as to improve the working efficiency.
