FMBT-21 module overview
The FMBT-21 Modbus/TCP 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
