Hello All,

I'm in the process of tuning a motor and I understand almost everything that is happening. The only thing that doesn't really make sense is how frequency relates to the speed of the motor. For instance, let's say my 3db point is at 100 Hz. I understand that from 0 to 100 Hz my motor is stable. If I have a 3000 RPM motor, how does 0 to 100 Hz relate to the maximum speed I can run the motor and still have precise positioning.

Thank you
