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

This blog post is not only intended to provide a graphical illustration but will also explain the procedure and the operational concept involving the wiring principle of the forward reverse motor control circuit with the use of a PLC (Programmable Logic Controller).

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

To help facilitate for a better understanding and further learning and training on the concept of the reversible Direct On Line (DOL) control circuit (ckt) covered in our previous article, a flowchart diagram is presented below as a follow up learning guide which shows a schematic representation of the sequence of operation for the starting and stopping and running operation of a reversible DOL electric motor control circuit in order to provide a visual aid to help diagrammatically visualize how the control circuit flows.

A how to guide for the Control Circuit of a Forward Reverse Electric Motor Controller

Controlling the AC induction motor's rotation either in the forward or reverse direction with the push of a button is made possible by the forward reverse control circuit. The electrical diagram below illustrates the operational sequence of the forward reverse control system specific for the command of the forward reverse power circuit used in every electrical industry involving industrial process automation control technology.

A how to guide for the Power Circuit of a Forward Reverse Electric Motor Controller

There are certain applications that requires forward and reverse direction of motor rotation, such as a conveyor system, or perhaps the opening and closing of valves. Another example is with overhead cranes which would also require a hoist up and down function, traverse forward and backward, and a left and right traveling function. Such application would most certainly make use of a forward and reverse motor control which is intended to achieve clockwise and counter clockwise motor rotational direction.
