WebSep 1, 2010 · Speed or step response time is inversely related to the galvo/mirror inertia and resonant frequency, and is typically specified as the time to move to 99% of 0.1° (mechanical) positioning move. Maximum rms frequency or repetition rate is related to both the bandwidth and the capability of the galvo to dissipate the heat of high currents, rate ... WebDec 10, 2024 · Due to the errors of the servo system and the errors of the ball screw drive system, the positioning errors inevitably occur in the process of CNC machine tools. The measurement of traditional equipment is limited by a fixed measurement radius and a single degree of freedom, which can only be measured within a fixed plane. In this paper, four …
