Overview

The ABB ACS550-PD-038A-4 is a wall-mounted, general-purpose packaged AC drive designed for reliable motor control in industrial applications. This 25 HP drive delivers 38A output current at 480VAC (380-480V range) with 3-phase input and output, making it ideal for pumps, fans, conveyors, and other variable-speed machinery. The NEMA 1 / UL Type 1 (IP21) enclosure provides protection against dust and light splashes, while the integrated disconnect switch and fuses enhance safety and simplify maintenance. The advanced control panel enables precise speed and torque adjustments, and the compact dimensions (39.9" x 10.2" x 11.9") and 75 lbs weight allow installation in space-constrained environments. Compatible with ABB’s ACS550 product family, this drive offers energy-efficient operation with built-in overload protection to extend motor life. The R3 frame design ensures compatibility with standard industrial mounting configurations. With a power factor of 0.98, frequency range of 48-63 Hz, and programmable acceleration/deceleration times from 0.1 to 1800 seconds, the ACS550-PD-038A-4 provides flexible control for demanding applications. Built-in Modbus RTU via RS485 enables easy integration with industrial control systems. The drive supports motor frequencies from 0 to 500 Hz and includes 24V DC auxiliary voltage (250mA max) for external devices. With a 1.1 overload rating, it safeguards connected equipment from temporary current spikes, extending component life.

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.
