Overview of the Ethernet network and the FENA-01/-11/-21 module 35
FENA-01/-11/-21 Ethernet adapter module
The FENA-01/-11/-21 Ethernet adapter module is an optional
device for ABB drives which enables the connection of the drive to
an Ethernet network.
Through the adapter module you can:
• give control commands to the drive (for example, Start, Stop,
Run enable)
• feed a motor speed or torque reference to the drive
• give a process actual value or a process reference to the PID
controller of the drive
• read status information and actual values from the drive
• reset a drive fault.
The protocols used to access these functionalities over Ethernet
are described in chapters:
• Modbus/TCP – Communication protocol
• EtherNet/IP – Communication protocol
• PROFINET IO – Communication protocol.
The adapter module supports 10 Mbit/s and 100 Mbit/s data
transfer rates and automatically detects the data transfer rate used
in the network.
Note: PROFINET IO uses only 100 Mbit/s in the Full duplex mode.
The adapter module is installed into an option slot on the drive
control unit. See the drive manuals for module placement options.
