Mitsubishi Inverter Protocol

[abdoon89]

Hello Everybody

I have a problem connecting FX3U to F700 using RS485 inverter protocol.

I built the PLC example provided in the Data Communication manual to run the inverter, and then modified all required parameters in the inverter. Yet, as I run the PLC it says that the inverter is not responding.

What could be the source of this problem?

Is it a must to use twisted pair cables? as I am using ordinary wires.

As long as send and receive wires are correctly connected and parameters are set, it should work.

It's been a while, but I know I used the sample code in the manual to set up my first one many years ago.

I have the same problem I would appreciate your help

To localize the problem you must:
- provide information about the inverter settings you have made;
- provide information about the application program;
- cable length between inverter and PLC.
