Modbus Connection ATV320 - hocine - 24.12.2024
Hello all,
i try to connect an ATV320 Variable speed drive from schneider electric with modbus connection.
I've made many settings but it's impossible for me to connect it to the LM.
In the LM, i activate the modbus RTU. i set the speed at 19200bps like the ATV
In the ATV I enable the modbus i set the adress to 1 but i don't what i need to choose in this settings
if some one can help me

Try swapping RS485 A/B and make sure that GND is connected between LM and Modbus device.

I switched the drive off and on again and now it works.
Thanks for your help Admin
