Overview

The ABB ACS550 AC Drive (SKU: ACS550-U1-059A-4+K466+L502) is a versatile variable frequency drive designed for precise motor control in industrial applications. This unit delivers a 40 horsepower output with a 59 Amp current rating, suitable for demanding loads. It operates on a 3-phase input voltage range of 380-480V AC, with a frequency range of 48 to 63 Hz. The drive features an IP21 and Type 1 enclosure, providing protection against dripping water and solid objects, making it appropriate for general industrial environments. Its advanced control capabilities ensure efficient operation and can contribute to energy savings. Connectivity is a key feature, with integrated Ethernet support for Modbus/TCP and EtherNet/IP protocols, facilitating seamless integration into modern automation systems. Additionally, it includes support for pulse encoders, enabling closed-loop control for applications requiring high precision. The drive offers programmable control connections including two analog inputs (0-10V or 4-20mA), two analog outputs (4-20mA), six digital inputs (12-24V DC, PNP and NPN), and three relay outputs (6A/30V DC, 1500VA/230V AC). It also includes built-in Modbus RTU protocol via RS485 serial communication. The compact dimensions of 27.1 x 8 x 10.3 inches and its wall-mount design allow for flexible installation in control cabinets or on machinery. This drive is well-suited for applications such as pumps, fans, conveyors, and other machinery found in manufacturing, HVAC, and process industries where reliable and adjustable motor speed is critical. The ABB ACS550 series is known for its ease of use, commissioning, and maintenance. 480V products carry UL, cUL, CSA, CE, C-TICK, and GOST-R approvals.

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.
