Hi Tomek What do you mean with your question? The maximum speed is given by your whole drive chain and does not have much to do with the Microflex Drives. The Motors have a maximum allowed rpm, maybe you use a gear and ballscrew. This gives you the maximum speed (Additionally ballscrews have a critical rpm, wich you shouldn't surpass).
I used Mint Workbench and the automatic tuning for the inner control loops (speed and torque). There you can also choose your maximum allowed Motor rpm. With my motors this was 4700rpm You have to take care when you choose the ppm for the incremental encoder feedback. Depending on the max. allowed encoder counter frequency of your interface card you have to reduce the value. (Nyquist) Maybe this helps Greets Marc Am Dienstag, den 17.04.2007, 22:53 +0200 schrieb Tomasz Brzozowski: > Thank You Marc > Your information are very helpful. > I have Mesa card 5i20 so I will try to use PWM output as DAC (with > capacitor filter).
