i already did that quant, i got all thess files from schneider site and other websites and read them all, still most of them explaining programming the drive through the display that i don't have i need to do it from software "somove" but the help of the program is so cursory and no useful tutorial on youtube so i asked here, my problem is that i don't know how to control the drive by plc through unitypro and somove without using the driver display i am new to the field so i may missing some concepts, thanks in advance.
