The ABB FENA-21 (3AUA0000089108) is a high-performance, 2-port Ethernet adapter module designed for seamless integration of ABB drives into industrial Ethernet networks. Featuring an integrated switch, this module supports daisy-chain and ring topologies, facilitating efficient communication without the need for additional external hardware.

Features

• Dual-port RJ45 connectivity with integrated switch functionality.
• Supports multiple industrial protocols: PROFINET IO (RT), EtherNet/IP, and Modbus/TCP.
• Enables drive control commands including Start, Stop, and Run enable.
• Supports motor speed and torque reference feeding.
• Allows for reading drive status, actual values, and resetting drive faults.
• Compatible with a wide range of ABB drives, including the ACS380, ACS480, ACS580, and ACS880 series.

Applications

• Power Generation: Control systems for auxiliary and main machinery in large power plants.
• Food and Beverage: Integration for packaging machinery, filling lines, and conveyor systems.
• Automotive: Management of conveyor systems in painting, body, and assembly workshops.
• Process Industry: Control of mixing equipment, ventilation fans, and circulating water pumps in chemical and petroleum facilities.

Technical Specifications

Installation Guidelines

• Ensure the drive is powered down and the DC bus is discharged before installing or removing the adapter module.
• Handle the module using ESD-safe practices to prevent damage to sensitive electronic components.
• Insert the module into the designated option slot on the drive; ensure it is seated firmly and secured with the provided mounting screws.
• Use shielded twisted-pair (STP) Ethernet cables to minimize electromagnetic interference (EMI) in industrial environments.
• Route communication cables separately from high-voltage power cables to maintain signal integrity.
• Verify that the drive firmware supports the FENA-21 module before commissioning.

FAQ

What is the primary advantage of the FENA-21 over the FENA-11?

The FENA-21 features two Ethernet ports and an integrated switch, allowing for linear (daisy-chain) and ring network topologies, whereas the FENA-11 is limited to a single port.

How are the communication protocols configured?

Protocol selection (PROFINET IO, EtherNet/IP, or Modbus/TCP) is configured directly through the drive's parameter settings.

Is this module compatible with safety functions?

Yes, the FENA-21 is designed to work in conjunction with drive-based safety modules, such as the FSO-12 or FSO-21, to implement advanced safety protection in industrial applications.
