Hi,
if that is the case, and the parameter is adjustable? then I would set it to 1250 line per rev
which corresponds to 5000 counts per rev.
With 1:1 coupled leadscrews at 5mm pitch then the resolution is 1um, an easy number to deal with.
The steps per unit (mm) in Mach would be 1000, easy. Set the max velocity in Mach at 5000 units/min
ie 5m/min. That would mean that Mach and the CSMIO would demand no more than 1000 rpm
from your servo.
Set the acceleration as high as is practical, excessive acceleration will cause over current events, so you
want to back off by 25% or so from that.
At 1000 rpm and 1250 lines/rev the A/B quadrature signals would be 21kHz, real easy going.
