These are coloquially known as the first harmonic, second harmonic and the third harmonic and ‘occur at 30RPM, 90RPM and 120RPM respectively. The majority of motor controls can very easily reduce the effects of the first and second harmonics = without much effort, while the third harmonic is still present. Standard 10 microstep GM215 with Sub-Microstepping The GM215 has proprietary Advanced Resonance Compensation (ARC) Exclusive Sub-Microstepping Damping that allows it to run a motor as smoothly as possible regardless of resonant speeds. The way this is accomplished is twofold: The GM215 has A standard stepper drive has either a fixed resolution or a fixed set of intelligent mathematics built in that can modify the motor’s waveform in real resolutions where each full step location of the motor is chopped to a time and has a settable motor profile adjustment that will warp the waveform smaller set of steps, known as microsteps. This means that a motor with according to user settings. a step angle of 1.8 degrees will have 2000 stopping locations with most ten microstep drives and will have noticeable pulsing at low speed. Ifa What does this mean for your application? It means the smoothest possible motor is being run at high speed this will not make a difference, but it motion from a stepper motor and unsurpassed compensation for motor can make or break a design at low speed. non-linearity. This can be the difference between your machine and your competition, giving you the edge in functional performance. The GM215 is different; every single microstep is further broken up into a further 16 Sub-Microsteps. This gives a step motor the smoothness of a servo with an 8000 line encoder on it while operating off of the same . . input frequency of a normal 10 microstep drive. Low speed jittering is ARC Damping: Perfectly synchronous motion, nonexistent with the GM215 which, when combined with high speed full i i. hing, will It in the th ible with regardless of motor nonlinearity. step morph ee e smoothest motor movement possible with *Minimum order quantity of at least 1000 per annum LEE SSS... gg:
