6.5.4 RS-485 Communication as a Command Input Device
Internal RS-485 communication can be selected as a command input device by setting DRV-06
(command source) in the Drive group to “3 (Int 485)”. This configuration uses upper level
controllers, such as PCs or PLCs, to control the inverter by transmitting and receiving signals via
the S+, S-, and RS-485 signal input terminals at the terminal block.
