BD600 – High Perfomance Vector Control Inverter

 

3

The series of BD600 products are high-performance inverter based on core technology platform of vector control and torque control, which have the functions of PG vector control, non-PG vector control and V/F control and are more suitable for requirements of high end control in terms of control accuracy. The modularized soft hardware functions meet the demands  of high-end industries, such as jack-up, lifting, paper making, chemical fiber, elevator, rolling mill and packaging.

Product features :
