Tutorial motor control o shows you how to make a small control circuit where all components are found in the component database. Architecture of a plc it consist essentially of. They are called ladder diagrams because they resemble a ladder with two vertical rails supply power and as many rungs horizontal lines as there are control circuits to represent. When including a plc in the ladder diagram still remains. Figure 5 below shows a schematic diagram for a plc based motor control system similar to the previous motor control example. Examples of control circuits 6 2 wire control 6 3 wire control 6 9 shunting thermal units during starting period 10. If interlock not required then simply remove the symbol from the diagram and connect with simple. Ladder diagrams ladder diagrams are specialized schematics commonly used to document industrial control logic systems. This figure shows the e stop wired to cutoff power to all of the devices in the circuit including the plc. The above figure shows the physical layout of motor starter however this would be designed through ladder logic in this plc tutorial.
Tutorial motor control o shows you how to make a small control circuit where all components are found in the component database. If we wanted to keep the motor running even after the operator takes his or her hand off the control switch es we could change the circuit in a couple of different ways. Tutorial panelbuilder o document a household panel by. Above figure does not show limit switch because it depends on external interlock like say level switch flow switch pressure switch etc depending on application. They are called ladder diagrams because they resemble a ladder with two vertical rails supply power and as many rungs horizontal lines as there are control circuits to represent. Inst maint wiring qxd 5 03. This motor control application can also be accomplished with a plc. O the project looks like pcsmotordemo1.
