Good day.

I have an issue connecting mitsubishi plc with a leadshine servo drive via rs 485 modbus serial.
Is there anybody that can assist me with this?
I am using a leadshine Elp servo drive elprs750z with a fx5u mitsubishi plc.
I do not have any experience on modbus serial programming and found a few examples and tutorials on different drives but i am not successful.
Please assist me if possible.

 

Take a look at this link

RS-485 serial settings (baud rate, 8 data bits, parity, stop bit) on both ends must be identical
Must know or assign a Modbus slave node ID to the drive.
