Role of Encoders and PLC in Electrical Control Drives of CNC Machines and Automation

Abstract

Today is the age of automation with the applications of Electrical Power and Drives, invariably, in all modern industries,CNC machines, transportation system, Metro Trains, Automobile Vehicles and domestic applications. PLCs and microcontrollers are inbuilt combination of various Digital Integrated Circuits. Most of the automobile vehicles(medium and heavy) are rapidly changing the mechanical drives and engine parts with electrical and electronic control devices. This includes,ignition control, combustion, engine cooling and emergency signals.Electrical drives are playing vital role in speed variation with reduced power consumption for heavy duty motor. In this paper,efforts have been made, to focus on the role and application of Encoder and PLC, in CNC Machines and Automation.
