Overview

The ABB ACS550-U1-012A-4+K454 AC drive delivers precise variable speed control for industrial motors up to 7.5 horsepower, operating on 380-480V AC input with a rated current of 11.9 Amps. This compact drive measures 14.5 x 4.9 x 8.3 inches and mounts directly to walls, simplifying installation in tight spaces. Its Type 1/IP21 enclosure provides basic protection against dust and dripping water, making it suitable for general industrial environments where exposure to contaminants is moderate. Designed for pumps, fans, conveyors, and similar machinery, the ACS550 offers advanced control algorithms that optimize motor performance while reducing energy consumption. The drive supports acceleration and deceleration times adjustable from 0.1 to 1800 seconds, allowing precise control over motor ramp-up and ramp-down to minimize mechanical stress. Built-in RS485 communication with Modbus RTU protocol facilitates seamless integration into existing control architectures, enabling remote monitoring and parameter adjustment. The ACS550 operates at 48-63Hz with a power factor of 0.98, ensuring efficient power utilization across global electrical grids. With a 1.1 overload capacity, the drive protects connected motors from temporary current surges without unnecessary tripping, extending equipment lifespan. This drive is part of ABB’s Low Voltage Drives portfolio, a trusted solution for industrial automation requiring reliable, compact variable frequency control.

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.
