 Selection of control source in Network operation mode (Pr.338, Pr.339)
• There are two control sources: the start command source, which controls the signals related to the inverter stand command
and function selection, and the speed command source, which controls signals related to frequency setting.
• The table below shows the commands from the external terminals and communication (RS-485 terminals or
communication option) in the Network operation mode.
