Rockwell Automation Introduces Allen-Bradley PowerFlex(TM) 700S AC Drive

Industry-first embedded standard controller option gives users complete programming and control capability at the drive level

MEQUON, Wisc., Sept. 9, 2002 - OEMs and system-level designers can improve system performance, enhance flexibility and optimize installation with the new Allen-Bradley PowerFlex(TM) 700S AC drive from complete automation leader Rockwell Automation. With selectable high-performance motor control algorithms, a high-speed data link and an integral position loop, the new drive is ideal for precise control of motor torque, speed and position in demanding applications such as printing, converting, and paper and steel processing. The PowerFlex 700S (0.37 to 55kW at 400 volts; 0.5 to 100 hp at 480 volts) is the latest addition to the PowerFlex family, a comprehensive line of AC drives for motor control ranging from 0.25 to 9,000 hp.

The PowerFlex 700S can include the DriveLogix(TM) embedded control option, which incorporates the innovative Allen-Bradley Logix(TM) control engine into the high-performance PowerFlex drive for application programmability and control of auxiliary functions in a single package. The drive can operate as a stand-alone device, communicating to a central controller, or as an intelligent drive and controller combination in a fully distributed architecture, eliminating the need for an external controller.

The PowerFlex 700S with the DriveLogix option utilizes the same programming environment and languages supported by all Logix platforms. With the first embedded drive control solution using an industry-standard PLC®, the drive can help manufacturers reduce training, installation and implementation costs, while maintaining high levels of performance and reliability.

High Performance and Flexibility. The PowerFlex 700S contains selectable, high-performance motor control algorithms utilizing Allen-Bradley Force Technology(TM) for closed loop or sensorless operation. This allows the drive to control either standard induction or servo motors, giving users the flexibility to drive multiple motor types with a single product. Unlike other drives, the PowerFlex 700S can accept multiple feedback devices ranging from standard to high-resolution encoders and resolvers.

For applications from simple indexing to complex electronic line shaft configurations, the PowerFlex 700S features a built-in position regulator for precise machine control and accurate positioning. In addition, the drive uses SynchLink(TM), a high-speed, drive-to-drive fiber optic data link, which transmits synchronized drive and application data for multiple machine sections. With SynchLink, the PowerFlex 700S synchronizes connected devices within microseconds, providing the highest level of drive coordination available.

Optimized Installation. As part of the PowerFlex family of drives, the PowerFlex 700S optimizes panel space with a bookshelf design that allows Zero Stacking(TM) or side-by-side mounting. The bookshelf design contains proven noise and voltage suppression characteristics, eliminating the need for external or motor-mounted filters. This design, combined with other space-saving features of the PowerFlex family and the embedded Logix controller of the PowerFlex 700S, optimizes installation by providing a powerful drive and control solution in a single, compact package.
