PowerFlex variable-speed drives extend power range

Power range of Rockwell Automation’s PowerFlex family of variable-speed ac drives has again been widened.


Future plans for PowerFlex 700H and 700S drives include still higher power ratings and inputs to 690 V.

Power range of Rockwell Automation ’s PowerFlex family of variable-speed ac drives has again been widened. OEMs and end-users stand to benefit from the modular structure, standardized packaging, and common features of these drives in lowering training, maintenance and inventory costs. Allen-Bradley PowerFlex line now includes new 700H ac drive and additional power ratings for 700S ac drive up to 450 horsepower.

PowerFlex 700H drive is designed for accurate open-loop (V/Hz and sensorless vector) speed control of motors for fans/pumps, conveyors, mixers, stamping presses, and simple extruders. It comes in power ratings of 200-450 hp (or 132-250 kW) at 400 and 480 V input. Standard I/O options include 24 or 115 V digital I/O points, plus analog I/O provision for flexibility. 700H drives reportedly integrate easily into manufacturing processes via NetLinx communication options, including DeviceNet, ControlNet, and EtherNet/IP networks.

PowerFlex 700S drive features selectable high-performance motor control algorithms, a high-speed data link, and an integral position loop—and is now available in ratings from 0.5 to 450 hp (0.37 to 250 kW) at 400 and 480 V. Precise control of motor torque, speed, and position in paper, converting, and steel processing are typical applications. 700S drives can include DriveLogix embedded control, an option that incorporates A-B Logix for application programmability and control of auxiliary functions in one package. This option allows the drive to work standalone, communicating to a central controller, or as an intelligent drive and controller in a distributed architecture, without the need for an external controller

CSA/cUL-certified, UL-listed, and CE-marked PowerFlex drives meet worldwide power ratings, packaging requirements, and electromagnetic compatibility (EMC) criteria.
