Interface Boosts Interpolator Performance [Nov. 16th, 2007|09:37 am]
[Tags|, , , ]

Delta Tau has added an EnDat feature to the ACC51 interpolator boards. These upgraded boards make it easy to connect quadrature encoders to PMAC controllers. EnDat is a bi-directional synchronous digital interface that was developed by Heidenhain to provide fast, reliable data transfer, yet needs only four signal lines between the encoder and the interpolator board.
The subsequent economy of wiring allows EnDat users to achieve significant cost reductions.

Savings of up to 50% have already been reported. The technical advantages of EnDat, combined with the performance of the 4096x interpolator chips used on ACC51 interpolator boards, gives encoder feedback a very high resolution. Importantly for engineers, this in turn leads to greatly enhanced velocity loop stability and much greater static and dynamic stiffness.

Currently the Delta Tau ACC51 boards implement EnDat Version 2.1, which provides power-up only via the serial interface, with subsequent positional information derived from sine/cosine data. In the near future support will be added for the recently released EnDat Version 2.2, which provides a fast serial interface for every servo cycle.

Booklet Tracks Manufacturing Trends [Apr. 30th, 2007|10:50 am]
[Tags|]

The Manufacturing Technologies Association (MTA) has published the 2007 edition of its pocket-sized essential facts booklet 'Basic facts'. The tables and charts track the trends up to 2006 for major parts of the manufacturing technology sector, including metal working machine tools, metal cutting tools and tool/work holding equipment.

It draws together data on UK production to 2005, exports and imports for these products and also has details of UK foreign trade by product type and the leading trading partners.

For machine tools, there is also a summary of the UK's position in the world market and, more generally a chart which summarises the trends for investment by manufacturing industry in the UK.

The trends in the machine tool business are reported in our regular series of press releases, but it is worth noting that whilst exports of machine tools increased for the 4th consecutive year and the share of world exports was broadly unchanged, there was a return to a trade deficit during 2006 owing to an increase in imports as a result of the improved UK market.

For the other aspects of manufacturing technology covered in 'Basic facts' 2007, cutting tools, like the machines they are used on, have a small trade deficit, whereas the tool/work-holding sector has a trade surplus.

Copies of 'Basic facts' are available on request, free of charge, from the MTA.

AC Tech Celebrates New Space, Ships Its Millionth Product [Dec. 13th, 2006|12:08 pm]
The 250 employees at AC Technology Corp. marked a couple of milestones recently, completing the move into a 75,000-square-foot addition and manufacturing their millionth product. The company, which was started in 1983 in the former Draper Mill complex in Hopedale, manufactures variable frequency drives, which are used to control the speed of electric motors. About 40 percent of the company’s products serve the international market, company officials said. Darrow F. Hanesian of Fiskdale, director of product management, said the Douglas Street company shipped 40 drives a month in 1994.

Last month, it shipped nearly 15,000, he said. AC Technology has achieved growth by investing in automation, he said. And while the company has added to its payroll, it has managed costs, Mr. Hanesian said. “We had to hire a great deal of people,” he said. “We’ve done some good managing of labor costs and our production costs.” Peter G. Joyal of Northboro, vice president of manufacturing, said the company builds all of its products in-house, including products for Lenze AG, the German company that purchased AC Technology in 1999. Lenze is a privately owned, international group of companies that manufactures power electronics and motors.

AC Technology has a plant in Kansas that assembles power transmission parts made in Germany. The company started out making variable frequency drives for electric motors, but expanded into other electronic motion control devices, , Mr. Hanesian said. Applications for the company’s products include controlling the speed and other factors on a pitching machine and controlling the pumps on carwash equipment. The University of Maryland, for example, uses AC Technology products to control the temperature and fans in the campus heating, ventilation and air conditioning systems. To accommodate expansion, last year the company sold one of its buildings and added on to the remaining 50,000-square-foot structure, for a total of 125,000 square feet, along with 12,000 square feet of basement space for the engineering department, Mr. Joyal said. The company gradually moved into the new space, completing the move in the spring.

The firm is profitable, but Mr. Hanesian declined to speak about its finances. In the first quarter ended July 31 sales were up 27 percent from the same quarter a year ago, he said. Mr. Hanesian said he expects the company will have $300 million in sales annually within five years. Most of the company’s U.S. competition has moved its manufacturing out of the country, he said.

“We’ve stayed ahead of the curve,” he said. “The way we were able to do it was to invest in research and development and automation. We didn’t spend when we didn’t need to, we invested wisely and we were not afraid to invest in our future. “We’re ahead of the growth curve, and we’ll spend to drive our growth,” Mr. Hanesian said. When competitors went through a few rounds of layoffs over the last five years or so, AC Technology seized the opportunity to snap up quality workers in a range of areas, he said. “When that happens, you’re letting good people go,” he said. “We went on a raid and got some good people in all areas.” The company held a celebration two weeks ago, with the production of its millionth product, a unit of the company’s new SMVector motor control. Mr. Hanesian said the company would continue to expand its product line.

“It’s a very fast-paced culture here,” he said. “That’s one of the main things that has kept us at the top.” Most of AC Technology’s competition is from multibillion-dollar companies with diverse manufacturing divisions, he said. “This is what we eat, sleep and breathe every day,” he added. “Each generation of electronics gets smaller, less expensive and has better parts.” Mr. Hanesian said the company still provides support and parts for its older “legacy” products. “It’s important for us to tighten up that contact” between customer service and users of the company’s products, he said. “While other companies are going to India (to provide customer service) and increasing that distance, we’re shortening it.” The company purchased 40 acres of land contiguous to the headquarters where up to 40,000 additional square feet of building space could be constructed, he said.

How Does A VFD Work [Aug. 22nd, 2006|05:05 pm]
[Tags|]

You can divide the world of electronic motor drives into two categories: AC and DC. A motor drive controls the speed, torque, direction and resulting horsepower of a motor. A DC drive typically controls a shunt wound DC motor, which has separate armature and field circuits. AC drives control AC induction motors, and-like their DC counterparts-control speed, torque, and horsepower.

Application As An Example
Let's take a brief look at a drive application. In Figure 1, you can see a simple application with a fixed speed fan using a motor starter. You could replace the 3-phase motor starter with Variable Frequency Drive (VFD) to operate the fan at variable speed. Since you can operate the fan at any speed below its maximum, you can vary airflow by controlling the motor speed instead of the air outlet damper.

New PS400 and PS500 Programmable Pressure Sensors [Jul. 30th, 2006|10:03 pm]
[Tags|]

TURCK Inc. introduces new programmable pressure sensors that combine high accuracy and performance with simple programming, resulting in an extremely user-friendly sensor. The PS400 and PS500 Turck Sensors are easily programmed via three controls: two push buttons for scrolling through programming features and one recessed enter key. The menu is clear and concise to allow parameters such as set points, reset points, output functions, analog ranges, and a range of special options to be programmed with ease. The menu also includes an optional electronic lockout that disables the push buttons from functioning until the lockout is removed. The high accuracy Turck programmable pressure sensors are specified with a switch point accuracy of =+/- 0.5 percent, generally exceeding what is required by the machine engineering sector.

The combination of high accuracy and flexible programming often allows a single sensor to replace several conventional sensors (with varying sensing ranges) resulting in a significant reduction in inventory. These Turck sensors feature a large, bright 4-digit, 7-segment LCD display with a constant indication of pressure in either psi (pounds per square inch), bar, kPa (kilopascals), or MPa (megapascals). This display is tilted at a 45 degree angle, and can be inverted electronically for easy reading in a variety of applications. The Turck PS400 and PS500 pressure sensors are encased in compact, 34 mm diameter housing with various threaded connections for simple, versatile installation. The Turck PS500 series also features a process connection that allows the housing to rotate 360 degrees for optimal viewing prior to locking the sensor in place. The innovative PS400 and PS500 Turck Pressure Sensors were designed to tolerate tough applications. Stainless steel housing with an integrated stainless steel M12 eurofast connector enables fast and reliable installation. The sensors also offer a variety of stainless steel pressure connections including G1/4 and 1/4-18NPT threads. The Turck Pressure Transmitters are highly resistant to overpressure and burst pressure, yet they also incorporate a patented medium stop system that prevents leakage when these levels are exceeded, which immediately seals the sensor if the pressure cell has been damaged. All of these features were incorporated to create a pressure sensor ideal for use in virtually any application.
