September 2005 1.0 Overview of Drive 1.1 Introduction The PowerFlex™ 7000L “C” Frame drive represents the third generation of medium voltage drives at Rockwell Automation. The PowerFlex 7000L “C” Frame medium voltage AC drive is part of the PowerFlex family of AC drive products. The Allen-Bradley PowerFlex™ family of Drives incorporates leading-edge technology, embedded communications, and significant commonality across multiple platforms, networks, operator interface programming and hardware. Designed for end users, solution providers and OEMs, PowerFlex 7000L “C” Frame liquid-cooled drives meet applications ranging from 3000 to 9,000 horsepower (2240 – 6715 kW). The PowerFlex 7000L “C” Frame drive is a general purpose stand alone medium voltage drive that controls speed, torque, direction, starting, and stopping of standard asynchronous or synchronous AC motors. It is intended for use on a host of standard and specialty applications such as fans, pumps, compressors, mixers, conveyors, kilns, fan-pumps, and test stands. Primary industries for these applications include petrochemical, cement, mining and metals, forest products, power generation, and water / waste water. The PowerFlex 7000L “C” Frame drive is a global product that adheres to the most common standards from NEC, IEC, NEMA, UL, and CSA. It is available with the world’s most common supply voltages at medium voltage, from 3300 to 6900 volts. � The design focus is on high reliability, ease of use, and lower total cost of ownership. � For 3300V designs, contact the factory.
