Brilliant Start Stop Motor Control Circuit
However the potential danger can exist because the jog button can potentially become the active seal in causing the load to stay on without the assistance of someone pressing the pushbutton.
Start stop motor control circuit. If the operator pushes the start button then the run coil will turn on and it seals itself in until the operator pushes the stop button. The inputs to this circuit are the start and stop conditions. 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.
If it is possible to eliminate using pushbuttons that make and break the control circuit at. There s a diagram shown in the process. The most common use of 3 wire control is a start stop control.
This video guides you how the stop start motor control circuits wiring done. You could imagine both are momentary buttons on an operator screen that are on while the operator is actually pushing the button. Motor control circuits are effective way.
It also pulls in a contact that is tied in parallel with the start button giving it another path for current flow once your release the start button. Pressing the jog button creates a current path directly to the load bypassing the seal in of the control circuit.
