max pulse frequency maybe 25kHz
nr of pulses per rev 2000 (10x microstepping)
-> 12.5rev/s * 20 mm = 250mm/s = 15m/min = 590ipm = plenty!

..but you need a pretty stiff ballscrew (and big motors!) to run it at
12.5*60= 750rpm

and the 'electrical resolution' i.e. size of one step would be 20mm/2000 =
0.01 mm which might be a little large.
