Modular systems drives AC890 systems drive 0.55kW - 1200kW Description 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 or servo motor applications. Features The AC890 can be configured for 4 different modes of operation Open-loop (volts / frequency) control This mode is ideal for basic, single or multi-motor speed control. Asynchronous motors Sensorless vector control With its ultra high performance sensorless vector algorithm, the AC890 delivers a combination of both high torque and close speed regulation without the need for any speed measuring transducer. Closed-loop vector control Brushless motors Full closed-loop flux vector performance can be achieved with the AC890 by simply adding an encoder feedback ‘technology box’. This provides 100% continuous full load standstill torque, plus a highly dynamic speed loop more than sufficient for the most demanding applications. 4 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%). Torque motors Compatible with a wide range of feedback options The AC890 is compatible with any AC motor and virtually any speed/position feedback options. With this flexibility you may not even need to replace your existing AC motor to achieve high performance, saving you time and money. • Incremental encoder • EnDat 2.1 (SinCos) encoder • Resolver International standards Complies with : - EN61800-3 (EMC) directive - CE marked to EN50178 (Low Voltage) directive - UL Listedto US safety standard UL508C Demanding environments For environments that have dusty, humid or corrosive atmospheres, the AC890 can optionally be supplied with conformally coated circuit boards that improve the drives resistance to corrosion, thereby increasing reliability and service life. Industries that would typically benefit from conformal coating could include : • • • • • • • Water and wastewater Paper and pulp processing Steel Marine and offshore Outdoor cranes Wind & wave power genera
