Control circuit specifications
2.3.5 When connecting the operation panel using a connection cable
When connecting the operation panel (FR-DU07) to the inverter using a cable, the operation panel can be mounted
on the enclosure surface and operationality improves.
2.3.6 RS-485 terminal block
2.3.7 Communication operation
REMARKS
· Overall wiring length when the operation panel is connected: 20m
· Refer to the following when fabricating the cable on the user side.
Commercially available product examples (as of Sep., 2006)

(4 paires)
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 315.
