Features and Benefits.

The AC890 can be configured for 4 different modes of operation .

open-oop (volts/frequency) control

This mode is ideal for basic, single or multi-motor speed control.Sensorless vector controlWith its ultra high performance sensorless vector algorithm,the Ac890 delivers a combination of both high torgue and close speedregulation without the need for any speed measuring transducer.Closed-loop vector control

Full closedloop flux vector performance can be achieved with the Ac890 by simply adding an encoder feedback ‘technology box. Thisprovides 1 00% continuous full load standstilltorque, plus a highly dynamic speed loop more than suficient for the most demanding applications.

4 Quadrant active front-end power supply moduleharmonic content is achieved (THD< 3%)

With this confauration, the eneray is fed back into the mains supply with sinusoidal currents and unity power factor a very low curen
