We see from your search that you're looking for information on the term "Absolute Encoder",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release DaimlerChrysler places large drive order from
Control Techniques, which we summarised at the time by saying "Around 600 Control Techniques drives were used in the Vaneo production facility in Ludwigsfelde and production was optimised by direct communication between PLCs and the drives".
Earlier in the week,
we featured the news release Positioning systems are easy to fit from
HMK Automation and Drives: "Integrated positioning systems combine a brushless motor, 24V drive, precision gearbox and absolute encoder in a compact easy-to-fit package".
In January 2008, we covered the news from Gefran SIEI UK
concerning its SieiDrive TPD32 Digital DC Drives
- take a look at DC drives boost flexibility
which says: "Gefrans EasyDrive PC configuration software allows the user to set up, diagnose and program the SieiDrive TPD32 Digital DC Drive in a graphical environment".
Take a look also at the news release from Rodriguez (UK), Geared motor slips into position precisely,
as well as Encoders take on hazardous duties from Industrial Encoder Corporation,
and Servomotors increase power ratings from Lenze.
