Personal-computer-based control is one of the fastest growing segments in machine control for monitoring a process and for discrete logic control of processes, such as material handling, machining, grinding, or gaging.Development of Windows NT by Microsoft (Redmond, Wa.) enabled PC-based real-time machine control to become reality.
Start the second 50 years! Hannover Industrial Fair begins its second half-century after a long, successful run that began under quite humble circumstances. This "world's largest industrial trade fair" arose from the post-World War II ravages of Germany.As Hannover Fair faces its second half century, more changes are certain due to economic and technology trends.
Fort Smith, Ark.— New products from Baldor include spindle drive motors, square flange pump motors, encoderless vector controls, hollow-shaft gear reducers, large 5800 frame motors, and a new line of advanced motion control products. In addition, the company recently introduced its new Standard-E motors that comply with the now-in-effect Energy Policy Act.
"Control products just keep getting more advanced, yet simpler to use,"was the consensus among editors at Control Engineering when it was time for them to choose the best control products of 1997. For the 11th consecutive year, the editors chose the 50 best products based on three criteria: technological advancement, impact on the market, and service to the industry.
Well, you asked for it. The 1998 edition of one of the world's largest manufacturing and technology shows is tanned, rested, and ready to go seamless.Evolving as a result of recent feedback from visitors and exhibitors requesting an even more streamlined and workable event, this year's National Industrial Automation Show (NIAS), and the three other shows that make up National Manufacturin...
Despite the temptation, size alone is not the right descriptor for ac "microdrives"—those ultracompact variable-frequency drives (VFDs) that sprouted during the first-half of the 1990s. For quite a while, it seemed, each new model would be even more miniature than the one announced just a month or so earlier.
Operating Systems Hardware Platform Motion Control Open Device Level Networks User Interface Control Software Manufacturing Information System (MIS) Level Networks Application Programming Interfaces (API) It should be clear to the controls community that GMPTG is not trying to dictate the development of OMAC by specifying technical details for every aspect of OMAC. GMPTG is not going to lead the development of any new technology but will ride the technology wave! However, GMPTG engineers are not oblivious to the technical issues associated with OMAC systems. In this section, several OMAC technical areas will be examined.
Motion control, as other technologies, has its fair share of special terms. Not all of them are rigorously defined; some require blending to suit the specific audience. Here's a sampling of some well-known and not-so-well-known terms.A motion control system typically consists of a controller to process motion algorithms and signals; an amplifier to boost signals to a level needed to p...
