Parker AC890 Compact Modular System AC Drive

The AC890 is a compact, modular systems AC drive engineered to control speed and position of open-loop and closed-loop, single- or multi-motor AC induction or servo motor applications, up to 500HP.

The Ac890 is a compact, modular systems drive engineered to control speed and position of openloop and closedoop, single- or multi.motor Ac induction or servo motor applications. Compatilble with a wide range of feedback options, the Ac890 may be used with any ACmotor and virtually any speed/position feedback options. With this flexibility you may not even need to replace your existing Ac motor toachieve high performance, saving you time and money. The Ac890 is available in 380-460/500v 3-phase 0.75 to 500HP and 220v-240V 3phase 0.75 to 10HP.

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
