Parameter
● Combination of computer and multiple inverters
SC-FRPC
Fig. 6-113: Connection of a computer to several inverters
The inverters may be affected by reflection depending on the transmission speed or transmis-
sion distance. If this reflection hinders communication, provide a terminating resistor. If the PU
connector is used to make a connection, use a distributor since a terminating resistor cannot be
fitted. Connect the terminating resistor to only the inverter remotest from the computer. (Termi-
nating resistor: 100 )
