V9 series is a new generation of products that organically integrates the general needs of customers with the individual needs of customers and the industry needs. Using a new control technology without velocity vector sensor, it has better low-speed stability, stronger low frequency load capacity, and higher control accuracy of open-loop vector torque control. In addition to support V/F, open loop vector control, closed loop vector control technology, it also has V/F separation technology. It has the anti-trip performance beyond similar products and the ability to adapt to the harsh power grid, temperature, humidity and dust, greatly improving the reliability of the product.
