PI8000 is sensorless vector control (field oriented control, flux oriented control, indirect torque control) high performance frequency changer (variable speed drive, VSD, frequency inverter). It achieves perfect motor control via servo function, and offers comprehensive drive solution in motion control. 
 
This series vector control variable speed drives (VSDs, adjustable frequency drive) have the following features:
1. Sensorless Vector control (field oriented control, flux oriented control, indirect torque control) variable speed drive (vsd, variable frequency drive, frequency inverter, adjustable speed drive) with high performance, excellent quality and low pollution.
2. It achieves quick-response and precise control  by decoupling control of motor magnetic flux current and torque current, which makes the speed adjustment and torque control runs at a high degree of accuracy and wide range. 
3. Brand new & reasonal hardware platform, advanced processing technique and perfect testing equipment, which guarantees the reliability.
