Overview
The ABB ACS800-U31-0020-2 is a wall-mounted variable frequency drive designed for industrial applications requiring ultra-low harmonic distortion. This 20 HP drive delivers 56 A output current at 240 VAC, operating efficiently within a 208-240VAC input range. Its ultra-low harmonic design ensures compliance with stringent power quality standards, reducing electrical interference in sensitive environments. The NEMA 1 (IP21) enclosure provides protection against dust and light splashes, making it suitable for harsh industrial conditions.
This drive features a local or remote-mounted LCD display and keypad for real-time monitoring and control, allowing operators to adjust parameters without opening the enclosure. The compact yet robust design measures 32.12" x 10.43" x 15.35" and weighs 144 lbs, ensuring easy installation in space-constrained environments. The ACS800-U31-0020-2 is part of ABB's ACS800 product family, known for reliable performance in manufacturing, HVAC, and process automation applications.
Key specifications include 3-phase input and output, 0020 KVA power rating, and a frame size of R5. The drive's ultra-low harmonic technology minimizes energy losses and reduces stress on electrical infrastructure, contributing to lower operational costs. With ABB's expertise in low-voltage drives, this model delivers precise motor control, energy efficiency, and reduced downtime for demanding industrial processes.

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.
