We see from your search that you're looking for information on the term "Absolute Encoders",
and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest.
Let me be your guide.
Start with
the news release High-performance, all-digital servo drives from
Parker Electromechanical Automation USA, which we summarised at the time by saying "Parker's Electromechanical Automation Division, a leading supplier of motion control technology, has announced four Compax3 servo drives with high-current power
levels".
A couple of weeks before,
we featured the news release DSP based servodrives for precision motion control from
Gefran SIEI UK: "The ArtDrive-S XVy-Evolution series high performance DSP based servodrives for precision motion control applications have been launched by Gefran".
In February 2007, we covered the news from Halifax Numerical Controls
concerning its Retrofit CNC and machine rebuild service
- take a look at Retrofit CNC raises long bed miller productivity
which says: "Control reliability and ease-of-use were the key factors in a subcontrac tor's decision to change to GE Fanuc for the CNC and drives of a long-bed, travelling gantry Cincinnati machining centre".
Take a look also at the news release from Micromech, Control systems for beam alignment girders at DLS,
as well as Five more servo geared motors added to range from Lenze,
and Rotary encoders include fieldbus versions from Telemecanique.
