This Motor Control Ladder Diagram is divided into two sections. The first is the power component, and the second is the control component. The core focus of the power portion is to show the flow of power to a motor or other devices in the factory environment. The primary focus of the power section is to show the flow of power to an engine or other device in a factory environment. The focus of the control section is demonstrating control of that motor. The use of the symbols depicted in the Motor Control Ladder Diagram is critical for both power and control. The symbols differ and are somewhat arbitrary depending on where you are and, in some cases, the company you work for.
