SVX9000 GENERAL PURPOSE INDUSTRIAL DRIVES Compact, modular solution to variable speed applications.
At the core of the SVX9000 is sensorless vector control technology coupled with an adaptive motor model and sophisticated ASIC circuit features. The motor flux model is based on measurements of all three output currents and the voltage as given by the ASIC circuit. The model automatically identifies motor parameters for both the sensorless vector mode and the U/f mode, keeping track of changes in the parameters over time. The vector control is carried out in a system of stator flux coordinates, which is immune to small variations in measurements and motor parameters. Sensorless Control Performance
