High resolution closed-loop steppers

[Voicecoil]

That's interesting 'coz on page 6 of the manual it says encoder resolution of 4,000, 10,000, 16,000 etc. ppr ....I was wondering how they achieved that... I don't think I'd ever want to push it as far as 32,000, just 4,000 or 10,000 would potentially provide a useful increase of resolution over the standard 1,000ppr.
