Figure 5 below shows a schematic diagram for a PLC based motor control system, similar to the previous motor control example.

Modern electrical machine tool equipment may vary from that of a single-motor machine (such as a drill press that performs simple, repetitive operations) to very large, multimotored automatic machines, which contain highly complex electrical control systems. Typically, these machines are especially designed, factory-wired, tested by the builder and then erected in the plant.

Two of the phases are also connected to the transformer to power the logic. The start and stop buttons are at the left of the box (note: normally these are mounted elsewhere, and a separate layout drawing would be needed).

From an electrical standpoint, industrial machine equipment and tools - from drill presses to multi-motored automatic machines.
By Blandine Honorine. Electrical Wiring. Published at Saturday, January 20th 2018, 01:41:31 AM. Conductors and cables should run from terminal to terminal without any intervening joins. This refers to making a joint in the middle of a wire or cable. If it is necessary for any reason then use a suitable connector or terminal block. Don’t use a twisted and soldered joint.

When constructing junction boxes and pull boxes, you must be careful to exclude materials such as dust, flyings, oil and coolant. After you complete all wiring operations, you must seal all unused knockouts or openings.
By Claudie Ulysse. Electrical Wiring. Published at Friday, January 19th 2018, 20:08:48 PM. Wiring diagrams show the connections to the controller. Wiring diagrams, sometimes called “main” or “construction” diagrams, show the actual connection points for the wires to the components and terminals of the controller.
