OPERATION VIA COMMUNICATION FROM RS-485
TERMINALS
Installing the control terminal option FR-E8TR allows RS-485 communication via the RS-485 terminals instead of the PU
connector on the standard control circuit terminal block.
Required parameter settings (refer to
For the initial setting and specifications for RS-485 communication via the RS-485 terminals, refer to the FR-E800 Instruction
Manual (Communication).
As is the case with RS-485 communication via the PU connector when the standard control circuit terminal block is installed,
RS-485 communication via the RS-485 terminals allows communication operation and parameter settings using the Mitsubishi
inverter protocol (computer link communication), MODBUS RTU communication protocol, or BACnet MS/TP protocol.
For the details on communication specifications and initial settings for the Mitsubishi inverter protocol (computer link
communication), MODBUS RTU communication protocol, and BACnet MS/TP protocol, refer to the FR-E800 Instruction
Manual (Communication).
CAUTION
Always reset the inverter after making the initial settings of the parameters. After changing the communication-related parameters,
communication cannot be made until the inverter is reset.
