Igor, check tacho feedback with a real scope no amplifier connected turn slow and steady ( big wheel helps , may need DC supply to release any brake ) look for mechanical influences like brushes, armature slots, bearings, connections
then attach amplifier and observe with NO motion when no motion you have your quietest signal, this is your base tacho signal, it wont get any better than this if you look with scope at tacho feedback before the above simle tests, you will see a sum of many smaller items. regards tomp ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
