UNDERSTANDING PROGRAMMABLE LOGIC CONTROLLERS

Image
  Modern industrial automation systems are smarter and more advanced than ever before. But have you ever wondered how did they get this way? What gives them the power and capability? What drives them? The answer is the PLC. So now the questions are ‘What does PLC stand for?’;‘What does a PLC do?’ Read on for a detailed introduction to PLCs. What is a PLC? First let’s learn the  PLC full form .  PLC stands for  Programmable Logic Controller. According to Wikipedia, “A  programmable logic controller  (PLC) or  programmable controller  is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.” The  PLC  or  Programmable Logic Controller  is the heart and brain of industrial automation.It is a specialised computer control unit th...

BASICS OF SERVO MOTOR CONTROL

Ever wondered how metal cutting & forming machines provide such accurate motion for milling, lathes, etc.? Or how a robotic vehicle in military application controls bomb detonation with careful precision? Or how do spinning machines in textile factories operate with unfailing accuracy and consistency for repetitive tasks? It’s all thanks to the precise control of servo systems. Let’s start with a fundamental question: What is a servo? Technically, the term ‘servo’ refers to a function and not a specific device, although the term is used as a short form for a servo motor or servo system. DIFFERENCE BETWEEN SERVO MOTORS AND DRIVES? To many, a servo drive and a servo motor can seem like the same thing because they are often used together in tandem. In reality, they play different roles in automation. What is a servo motor ? Servo motors are electrical devices made up of various parts, that move and rotate parts of a machine with efficiency and precision.  Servo motor functions ...
