A Talk on the Motion Control Basics | Motion Control Components
Whenever we talk about motion control in semiconductor fabrication, we probably visualize robotic arms placing wafers on vacuum chucks, shifting the exposure area in step-and-scan lithography machines. In semiconductors, fabrication time is ‘money’ & yield is ‘king’. The main aim is to gain more precision, get there faster, and accelerate harder. Therefore, the advanced trends in motion control are offering the tools to do just that. You can rely on the Kensington controller for the best results.
In today’s ever-shrinking feature sizes, contamination control is most important in ensuring yield. Though the fab floor is maintained within the process tools, the standard is considerably tighter. Basically, motion controllers are pieces of electronics that run software to command movements on automated pieces of machinery.
Typically, motion controllers are designed to manage the particular actuator type on the axes they command. It means that these controllers include the intelligence to command either electric actuators or hydraulic actuators.
Motion Control Components | Automation Technology for the Semiconductor & Electronics Industry
The designers of motion control systems presently must select from among an ever-expanding array of components as well as technologies. With the continuing improvement in microprocessors, programmable logic technology, power semiconductors, & software, the designers of motion control systems are working to achieve highly reliable, accurate, as well as sophisticated results than ever before. In order to realize these improvements, the designers should prefer the most suitable motion control components & technologies among a broad range of products as well as suppliers.
In addition to this, making these choices involves not just choosing the top-quality components, like controllers, motors, motor drives, as well as feedback sensors, but also planning how these components & others will work together in the finished system.
The initial step of choosing motion control components is to define the system’s basic needs clearly. Does the system require the control of force, speed, position, or maybe a combination of these? Is accuracy the most important goal or repeatability? How many axes of control are needed? Do multiple axes require coordination, as they are in an x-y-z arrangement? The most common mistake is not considering these special needs of an application when picking components.
Once the designer gains a complete understanding of the exact requirements, the expert is ready to find out which products will best meet the requirements of the system. Undoubtedly, mechanical factors have much more effect on the electronic design of motion control systems than the electronic design of mechanisms. The product flow, throughput, human operator needs, as well as maintenance problems help determine mechanics, that in turn helps decide electronic as well as software requirements. Thus, electronics engineers must understand the mechanics of motion control systems to attain successful electronic designs.
Solving Unique Challenges!
Though motion controllers are particular to the task of moving equipment, they share some commonalities with other controls for automation in process applications. These process setups are dedicated to batch material processing, chemical production, climate control, as well as similar tasks in such disparate industries. For the best results, you can rely on the Kensington motion controller.
And discussion about it goes on.
