Start Stop Motor Control Diagram. A switch is wired in series with the seal in of the pilot device. Start stop contactor wiring diagram in 2 positions working principle.
Stop button or plc input i01. Sometimes the cables will cross. Figure 1 is a typical wiring diagram for a three phase magnetic motor starter.
When you press the start button and the stop button is not pressed the 24vdc relay energizes and it pulls in the r1 contactor that feeds three phase power to the motor.
In a jog motor control a dual push button with one normally motor control open and one normally close contacts is inserted in between the normal stop and start push button of the across the line magnetic starter. Stop button or plc input i01. It also pulls in a contact that is tied in parallel with the start button giving it another path for. In this ladder logic example there are two inputs.
