Cost-effective micro drives get even more powerful


The Allen-Bradley PowerFlex range of AC drives has been extended with the introduction of the PowerFlex 4M, the smallest and most cost-effective member of the PowerFlex family of drives. PowerFlex 4M is available in three frame sizes from A to C to offer power from 0.2-11kW, providing Machine Builders and end users with a space saving, simple-to-install and easy-to-use AC drive that will satisfy a broad spread of applications.

Feed-through wiring, DIN-rail mounting and programming ease give users out-of-the-box AC drive control for motor control retrofits and new applications.

In new and retrofit applications, the new Allen-Bradley PowerFlex 4M AC drives from Rockwell Automation give users economical, easy-to-program variable frequency motor control with feed-through wiring for quick installation. Engineered for ease of use, the PowerFlex 4M AC drive helps users minimize mechanical machine stress and increase application flexibility.

“Machine Builders and panel builders understand the performance-enhancing, motor-protecting benefits of AC drive control, but using this flexible motor control option is often limited by wiring issues and complex programming,” said Felix End, European Product Manager, Rockwell Automation. “PowerFlex 4M AC drives give traditional electromechanical motor control and seasoned AC drive users powerful volts-per-hertz motor control in a space-saving package designed for ease of use.”

• Compact Package. With power ratings from 0.2 to 11kW (0.25 to 15Hp) and voltage classes of 120, 240, 400 and 480V, the PowerFlex 4M AC drive is the smallest and most cost-effective member of the PowerFlex family of drives. The PowerFlex 4M

A Frame measures 174mm H x 72mm W x 136mm D; the B Frame 174 x 100 x 136mm; and the C Frame 260 x 130 x 180mm. All frame sizes feature Zero-Stacking, which saves panel space by eliminating space between drives.

• Snap-In Installation. For ease of installation, the PowerFlex 4M A- and B-Frame drives are designed with simple DIN-rail, snap-in mounting features. Compared to traditional screw-in mounting, installing a DIN-rail-compatible PowerFlex 4M is significantly more time efficient.

• Ease of Setup. For ease of information sharing and setup, integral RS485 communications enable engineers to use the drives in a multidrop network configuration, and a serial converter module connects to any controller that has the ability to initiate DF1 messaging. Featuring the popular CopyCat function, an IP66 (NEMA/UL Type 4X) remote LCD keypad and an IP20 (NEMA/UL Type 1) handheld LCD keypad provide additional programming and control flexibility. Users can easily program, monitor and control the PowerFlex 4M drives with DriveExplorer and DriveTools SP software.

The drives meet UL, CE, CSA and C-Tick standards.
