I was wondering which method would be better to control my VFD for my mill. I have a Teco 7300 CV.
I'm looking at using either analog 10V, modbus RS232 or RS485. I currently have the RS232 cable and if modbus is a better way to control it is RS232 or RS485 better? I can pick up the RS485 cable for around $20.
My analog signal if that is a better route would be coming from a Kflop/Kanalog board.
