Overview
The ABB ACS800-U31-0040-5+K458 is a wall-mounted variable frequency drive (VFD) designed for industrial applications requiring ultra-low harmonic distortion. Rated at 40 HP with a 55A output current, this drive operates efficiently within a 480VAC voltage range (380-500V) and supports 3-phase input and output. Its NEMA 1 / UL Type 1 (IP21) enclosure ensures reliable operation in standard industrial environments, protecting against dust and non-corrosive contaminants.
This drive features a local or remote-mounted LCD display and keypad for easy configuration and monitoring, along with a ModBus adapter for seamless integration with automation systems. The ACS800 series is known for its energy efficiency and advanced control features, making it a trusted choice for demanding applications. Weighing 144 lbs and measuring 32.12" x 10.43" x 15.35", it is ideal for space-constrained installations. The drive's ultra-low harmonic distortion minimizes electrical interference, ensuring compliance with strict power quality standards.
Key applications include pumps, fans, conveyors, and compressors where precise speed control and energy savings are critical. The ACS800-U31-0040-5+K458 is manufactured by ABB in Denmark, a leader in industrial automation and drive technology.

FENA-21
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.
