Hi, Tim,

Full stepping at 200KHz wouldn't be of much use, as you say, because the
stepper would not follow (in most real situations). 

However if you are *microstepping* at 200KHz per microstep, and 10
microsteps per 
step (if I read their data sheet correctly) then it works out to more like
300ipm
max, which is a more reasonable maximum. 

Best regards,
