Selection of operation mode and operation location
(5) Selection of command source in Network operation mode (Pr. 338, Pr. 339)
⋅ There are two control sources: operation command source, which controls the signals related to the inverter start
command and function selection, and speed command source, which controls signals related to frequency setting.
⋅ In Network operation mode, the commands from the external terminals and communication (RS-485 terminals or
communication option) are as listed below.
