Electrical Wiring Diagram Forward Reverse Motor Control and Power Circuit Using Mitsubishi PLC

This blog post is intended to provide a graphically illustrated procedural concept involving the wiring principle of the forward reverse motor control circuit when using a PLC (Programmable Logic Controller).

A diagram of the ladder program contained inside the PLC memory specific to this function is also included below to clearly illustrate the operational sequence of command execution for this motor control system.

Electrical Wiring Diagram Star Delta Control and Power Circuit Using Mitsubishi PLC Program

This article is intended to diagrammatically demonstrate the concept of the wiring principle of a star delta (wye delta) motor control and power circuit when using a PLC (Programmable Logic Controller) ladder program to control the switching of a 440 volts induction motor.

Motor Start Stop Time Sequence Electrical Control Circuit Using PLC Ladder Program

The following is a sample tutorial of a typical timing sequence involving a start and stop function of a common DOL (Direct On Line) motor control circuit using PLC (Programmable Logic Controller) ladder program.

Types of electrical circuit connections - Basic tutorial on series and parallel circuit

There are mainly two basic types of circuit connection in an electrical system. These two basic configuration are most commonly known as the series connection and the parallel connection.

Although there are a lot of other complex circuits constructed from various designs and installation purposes to suit specific electrical requirements, all of them are based from a combination of these two basic wiring principle.

Learn how to use an electrical multimeter - A basic introduction tutorial and multimeter manual

Introduction:

When you get behind the wheel of a car, what is the next thing that you would most certainly do besides closing the door and strapping yourself securely to the seat. Obviously enough, it is expected that you would turn the ignition to start the engine, grab the steering wheel, shift the gear and step on the pedal because this is the most basic routine that every driver would instinctively do to drive a car. This inherent trait almost comes as a second nature to all experienced driver, which simply is an automatic pattern of behavior in reaction to the specific situation of driving a motor vehicle.

Similarly, having an aptitude for using an electrical multimeter would always come in handy when working with electrical circuits. Just as it is vitally important to have a thorough understanding about what makes up the structure of an electrical circuit, which involves the installed electrical switching components that are connected in such a way as to provide a continuous controlled flow of electrical path between the circuit's supply or source voltage down to the connected load in the circuit, so too is the importance of using a multimeter in circuit analysis.
