I'm looking at driving 2-phase, 1.8 degree/step stepper using microstepping/sine-wave drive. I don't need to increase position resolution, but I need to minimize vibration to a bare minimum. I have never had a fancy microstepping driver so I was wondering--do the 1/8th and 1/16th-stepping microstep drivers really result in a smoother-running motor compared to full or half-stepping with an H-bridge?
I will probably implement my own microstepping in software. Does anyone know the PWM frequency used by microstepping drivers? I looked at the datasheet for this one
But it never says what the actual PWM frequency is. I'm guessing like 5kHz but it would be nice to know so that I can copy it.
