5.4.3 Bus Mode (Serial channel / Field bus)
There are two built in communication protocols available: Modbus RTU/ASCII and NFO Classic (legacy NFO
protocol). Both communicate using either USB or RS485. For other fieldbus communication protocols, the inverter
also accepts an Anybus CompactCom module as an option. Please contact NFO Drives AB for more information.
For controlling the inverter or altering its parameters via Modbus or NFO Classic protocol, the Windows program
“NFO Sinus Manager” is available and can be downloaded from www.nfodrives.se
