Parameters
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.
