Motion Control & Drives


Compact motor drive for up to 3,7 kW (5 hp)

April 2002 Motion Control & Drives

Available in power ratings from 0,2 to 3,7 kW (0,25-5 hp) and in voltage classes of 115, 230 and 480 V, the Allen-Bradley PowerFlex 4 AC drive is designed to meet global OEM and end-user demands for flexibility, space savings, and ease of use, providing a cost-effective speed control option for applications such as machine tools, fans, pumps, conveyors and material handling systems.

Ease of installation and use

Suitable for installation in machines and control panels, the drive features an integral keypad with a local potentiometer for easy control. This new drive, with its intuitive keypad, contains a group of parameters that enables Quick Start - for fast and easy start up. The PowerFlex 4 is also designed with simple access to terminal blocks for ease of wiring. For ease in programming and monitoring, the new drive features integral RS485 communications, making it compatible with Allen-Bradley DriveExplorer and DriveExecutive software when using a serial converter module.

Flexible, space-saving size

Rockwell says that the innovative and cost-effective PowerFlex 4 was created without sacrificing flexibility. The microdrive is available in an IP20 compact package style that can be either DIN rail or panel mounted. An optional IP30/NEMA 1 kit provides added application flexibility. The compact PowerFlex 4 also permits zero stacking, which allows drives to be mounted side by side, saving valuable panel space. An integral filter version is available for single-phase 230 V designs further reducing the drive's footprint when complying with EMC requirements.

Worldwide compatibility

Like all products within the PowerFlex family of drives, the PowerFlex 4 is designed to meet worldwide power ratings, packaging requirements and electromagnetic compatibility (EMC) criteria.

Commonality within the PowerFlex range allows the user to feel familiar with programming and start up of any PowerFlex AC drive. Rockwell Automation ensures worldwide performance reliability through an extensive testing programme and local support services.
