Overview
The ABB ACS800-U31-0120-5 is a wall-mounted ultra-low harmonic drive designed for industrial applications requiring precise motor control and compliance with harmonic distortion standards. Rated at 125 HP with a 156A output current, this drive operates at 480VAC with a voltage range of 380-500V, making it suitable for global installations. Its NEMA 1/UL Type 1 (IP21) enclosure provides protection against dust and non-condensing moisture, ensuring reliable operation in harsh environments.
The drive features a compact R6 frame design with dimensions of 38.19" (H) x 11.81" (W) x 17.28" (D) and weighs 221 lbs, ideal for space-constrained applications. A local or remote-mounted LCD display and keypad enable easy monitoring and configuration. With a 0120 kVA rating and 3-phase input/output, it delivers efficient performance for pumps, fans, conveyors, and other industrial machinery. The ACS800-U31-0120-5 ensures energy savings and reduced electrical stress on the power system.

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.
