We are tasked to design our own or mechanism where we can apply 3 phase motor starter like a simple start-stop-jog motor starter or forward-reverse motor starter. I'm planning to do a dumb waiter system or a conveyor system, but I can't think of a way to create it a closed loop system without using arduino or plc. I'm new to this so I'm having a hard time. Can you please me? Your help will be much appreciated. TIA
