Am I correct in thinking that one pulses equals one step?

If so then I pulse equals 1.8 degrees... therefore 200 pulses equals one full rotation... One full rotation equals 5mm (with my Chinese 1605 and 2005 ballscrews)....

200,000 pulses (200KHz)/ 200 pulses x 5mm = 5000mm/s = 5m/s theoretical maximum velocity...

Is this correct?
