(1) Select control source for NET mode (Pr. 550)
The control location for NET mode can be selected to be from either the inverter's RS-485 port or a
plug-on communication option card. Therefore, to control the inverter via the option card, Pr. 550 must
be set to either "9999" (default) or "0" (Communication option input valid).
