Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual page 385

 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 following table shows the commands given via the external terminals or given through communication (via the RS-485
terminals or the communication option) in the Network operation mode.
