I can use a magnetic linear encoder with a 10u resolution that's
comparable with the axis resolution (20u): is this a problem ? With
this setup will I get too many rest vibrations ? Using the solution
I've described before can closed loop be used without problems ?
Maximum speed isn't the main requirement: I need to "eliminate" all no
linear mechanical effects as backlash to obtain a precise positioning
with a low settling time.
