AC890 System Drive
The AC890 is a compact, modular systems drive engineered to control speed and position of open-loop and closed-loop, single- or multi-motor AC induction or servo motor applications. Power range up to 1000kW. The AC890 can be configured for 4 different modes of operation : Open-loop (volts / frequency) control Sensorless vector control Closed-loop vector control Quadrant active front-end power supply module With this configuration, the energy is fed back into the mains supply with sinusoidal currents and unity power factor; a very low current harmonic content is achieved (THD < 5%).
