Mounting The Operation Panel (Fr-Du07) On The Enclosure Surface; Communication Operation - Mitsubishi Electric FR-A720-00030-NA Instruction Manual

2.3.5

Mounting the operation panel (FR-DU07) on the enclosure surface

Having an operation panel or a parameter unit on the enclosure surface is convenient. With a connection cable, you
can mount the operation panel (FR-DU07) to the enclosure surface, and connect it to the inverter.
Use the option FR-CB2, or the following connector and cable available on the market.
Securely insert one end of connection cable into the PU connector of the inverter and the other end into the
connection connector of the operation panel (FR-DU07) along the guides until the stoppers are fixed.

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 335.
