You'll get zero if you spin the MPG backwards. I think it's limited to 1.0, and it's a scale factor like feed override. It's called something like motion.adaptive-feed.
You do have to program M52 (or M52 P1) to enable AFO, and M52 P0 to disable it. - Steve ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
