Finally got back to doing something with the system. Lots of electrical noise issues whenever the AC Servo is enabled but mostly with MACH3. Moving cables and the motor solved a lot of those problems.
Booting instead with LinuxCNC has been very successful. I have LinuxCNC with the parallel port configured to create 1kHz on PIN14 and DIR on PIN16 out through the PMDX-126. Through my adaptor board I can run the Bergerda AC Servo from 135 RPM all the way up to 2950 RPM. The PWM to 0V-10V board was only $11.23 Cdn and works best with a max of 1kHz. Any higher and the low end won't drop below about 500 RPM. For the parallel port version I can do this: setp pwmgen.0.pwm-freq 1000.0 That doesn't work for setp hm2_7i92.0.pwmgen.00.pwm-freq 1000.0 How do I set the PWM frequency? Googling hm2_7i92 doesn't turn up anything that is helpful.
