Overview
The ABB ACS800-U11-0020-2 is a wall-mounted regenerative drive, part of the ACS800 product family, engineered for industrial applications demanding precise motor control and efficient energy recovery. This robust unit is rated at 20 horsepower (HP) and delivers an output current of 56.1 Amperes (A). It operates on a 240 Volt Alternating Current (VAC) supply, with a voltage range of 208–240 VAC, and is designed for 3-phase input and 3-phase output configurations. The drive features a NEMA 1 / UL Type 1 enclosure, which also corresponds to an IP21 protection rating, offering defense against solid objects larger than 12.5 mm and vertically falling water drops, making it suitable for environments where dust and light splashes are present.
Installation flexibility is a key feature, with the ACS800-U11-0020-2 designed for wall mounting. It includes both a local and a remote-mounted LCD display and keypad, facilitating straightforward operation and comprehensive monitoring of drive parameters. The drive has a KVA rating of 0020. Its physical dimensions are a height of 32.12 inches, a width of 10.43 inches, and a depth of 15.35 inches. The product weight is 144 pounds. The frame size is R5. The regenerative capability of this drive enables energy recovery during motor deceleration, which directly contributes to reduced power consumption and consequently lowers operational costs. This model is ideal for applications within manufacturing, automation, and process control sectors where enhanced energy efficiency, unwavering reliability, and minimized downtime are paramount for operational success. The ACS800-U11-0020-2 is engineered to provide consistent performance across a broad spectrum of industrial systems while requiring minimal maintenance.

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.
