INSTALLATION AND WIRING

2.4.7 RS-485 terminal block

⋅ Conforming standard: EIA-485(RS-485)

⋅ Transmission format: Multidrop link

⋅ Communication speed: MAX 38400bps

⋅ Overall length: 500m

⋅ Connection cable:Twisted pair cable

(4 paires)

2.4.8 Communication operation

Using the PU connector or RS-485 terminal, you

can perform communication operation from a

personal computer etc. When the PU connector is

connected with a personal, FA or other computer

by a communication cable, a user program can run

and monitor the inverter or read and write to

parameters.

For the Mitsubishi inverter protocol (computer link

operation), communication can be performed with

the PU connector and RS-485 terminal.

For the Modbus RTU protocol, communication can

be performed with the RS-485 terminal.

For further details, refer to the instruction

manual (applied).
