Here is a programming manual for Mit 300 seres controls, rotation stuff starts at page 184 of the PDF 172 of the scanned book. Its an old control but easy to use and it had a lot of options, and the manual is a free download. :) <http://www.meau.com/functions/dms/getfile.asp?ID=010000000000000001000000460900000>http://www.meau.com/functions/dms/getfile.asp?ID=010000000000000001000000460900000
In case that link to the PDF does not work here is the page, book BNP-A2943 should be second in the list. http://www.meau.com/eprise/main/sites/public/DOWNLOADS/-search_results?SType=3&DocType=010&SessionNum=&UserID=&Division=00010&Opt1=Yes&submit1=Search&Family=&ManualType=0055 It does a fair job of describing the interactions of the rotation and workoffsets and other things. Not the end all bible but a good place to start. _________ Andre' B.
