Hi Group! I´m really glad that I got a message from the group :) Thanks to the person who has solved this problem and to Steve mentioned this already. I use shielded cables and a differential input, but I still have a glitch in the ssi-transmission and according to the support of the card producer the card has a failure - hopefully :), so I will get a new one. I uploaded a screenshot http://imagebin.ca/view/gWIGpMhw.html of the halscope. You can see the signals turncpt (number of the turns), rawpos (Position in the turn) and the calculated position. When error occurs both values rawpos and turncpt spread. This may be an bit-failure - the driver I wrote shout be OK ;)
By then I have to wait. Thanks Bernd > -----Ursprüngliche Nachricht----- > Von: [email protected] [mailto:emc-users- > [email protected]] > Gesendet: Donnerstag, 30.
