Product Overview
The Allen-Bradley 20BD065A0AYNAND0 is a PowerFlex 700 adjustable-frequency AC drive manufactured by Rockwell Automation. It converts fixed-frequency, three-phase 480 VAC power into a controllable voltage and frequency for operating three-phase induction motors at variable speed and torque. With a continuous output current of 65 A, the 20BD065A0AYNAND0 is rated for 50 HP in normal-duty applications and 40 HP in heavy-duty applications. This makes it suitable for fans, pumps, compressors, conveyors, extruders, mixers, material-handling systems, and other rotating equipment where energy efficiency, process control, and mechanical stress reduction are priorities.
Housed in a Frame 3, IP20/NEMA Type 1 enclosure, the Allen-Bradley 20BD065A0AYNAND0 uses sine-coded PWM and supports V/Hz, sensorless vector control, and optional enhanced vector-control configurations. The installed vector-control cassette provides 115 VAC digital and analog I/O, allowing the drive to receive start/stop commands, speed references, and interlock signals while returning status, fault, and feedback information. Sensorless vector control delivers improved speed and torque regulation without an encoder, reducing wiring, cost, and failure points.
This specific catalog configuration includes a factory-installed brake IGBT, although it does not include an internal braking resistor. It also includes a second-environment EMC filter and common-mode choke to support compliance with the CE EMC Directive, and its printed-circuit boards are conformally coated for improved resistance to moisture, corrosive atmospheres, and conductive contamination. The drive has no Human Interface Module; a blank plate occupies the HIM position. Rockwell Automation has discontinued the PowerFlex 700 Frame 7–10 family, including the 20BD065A0AYNAND0, and recommends the PowerFlex 755 as an engineering-replacement platform. Nevertheless, verified spares remain essential for supporting installed PowerFlex 700 systems.
