This section provides an overview of the system conguration needed to use inverter communication.
Inverter communication is used over the built-in RS-485 port, communication board, and communication
adapter. Serial ports assignments are hard-coded as follows regardless of the system conguration.
5.2.2 System conguration
Depending on the connection method, use either a 10BASE-T or shielded twisted pair cable to connect with
devices over RS-485 communication.
CH2: communication boardCH1: built-in RS-485 port
CH3: first communication adapter
CH4: second communication adapter
PU
connector
(RJ45 connector)
Stranded-wire cable
(Use twisted-pair or 10BASE-T LAN cable)
Termination resistor
(Which is built in the FX5 PLC, and must be
arranged by the user for the inverter, and
supplied with or built in for other communication
equipment)
