Not sure why but the DB25 cable I was using for the IO on the DYN4 was generating most of the interference. Will have to look at options for replacing it. Down to about 0.15V at idle on the analog signal which is only slightly above the bench test voltages I was seeing. Hooked up the servo enable ...

No oscilloscope but I hooked up a 0.033uFd capacitor (closest I have) across the terminals and it slowed the rotation down to about 60rpm. Any idea what could be causing the interference? I tried a different power supply with the same results and everything other than the Acorn and the DYN4 is ...

From the specifications it looks like the Acorn is rated for up to 1mA on the analog output and the DYN4 has a max of 0.1mA draw so they should be compatible. I also found a wiring guide for this application on the DMM website and it doesn't look like a enable servo signal was required:

Hi,
I'm having issues driving a DYN4 spindle motor using the analog output on an V4 Acorn. I benchtested the analog out signal using both the manual process and the updated automatic test and both pass (a little on the high side). When I hook up the motor it will run slowly (around 200rpm) with the ...
