Overview

The ABB ACS550-U1-059A-2+L511 AC drive delivers precise variable speed control for industrial motors up to 20 horsepower (HP) with a continuous current rating of 59.4 Amperes (A). Designed for 3-phase input voltage ranges of 200-240 VAC (±10/-15%), this drive supports motor frequencies from 0 to 500 Hz, enabling flexible operation across a wide spectrum of applications. Its compact dimensions of 23 x 8 x 9.1 inches allow for wall-mounted installation in space-constrained environments, while the Type 1/IP21 enclosure provides protection against solid objects and dripping water, making it suitable for general-purpose industrial settings. The built-in Modbus RTU protocol via RS485 enables seamless integration with industrial automation systems. With adjustable acceleration/deceleration times (0.1 to 1800 seconds) and a 1.1 overload capacity, the ACS550 ensures reliable operation under transient load conditions. The relay output extension enhances connectivity for automated control systems. Ideal for applications such as HVAC systems, pumps, fans, conveyors, and compressors, the ACS550 optimizes energy efficiency and motor performance. Its auxiliary 24V DC supply (max 250mA) supports external sensors and control devices. The drive’s user-friendly interface simplifies setup and maintenance, reducing operational downtime. With a power factor of 0.98 and frequency range of 48-63 Hz, it adapts to diverse power environments while maintaining high efficiency.

The FENA 21 DualPort module supports Three protocols Modbus-TCP, EtherNet/IP, and the PROFInet IO RT network. The Modbus-TCP protocol is simply the Modbus protocol used on top of Ethernet-TCP/IP. Modbus-TCP is an open Industrial Ethernet network which has been specified by the Modbus-IDA User Organization. EtherNet/IP is based on the Common Industrial Protocol (CIP), which is also the framework for both the ControlNet and DeviceNet network protocols. PROFInet IO RT is an open network based on the PI Organization standard.
