I have a Hohman Designs Step to Voltage module that does that. It uses 0 to 25Khz for 0 to 10V. I couldn't use that with my ELS project because max step rate for that was 20kHz. But it would work with the Linux Installation instead of the cheapy 0-10V 1kHz PWM converter. I doubt the Bergerda AC Servo would care though.
