I think the RMHV is essentially the same as the DDCSV, and I don't think there is an option to use step/dir for spindle control. And I don't think the 0-10V is isolated. The only way you could get it to work with a non-isolated drive would be with a 0-10V to 0-10V isolator, but they aren't common or cheap (IIRC the last time I looked they were upwards of £150).
The easier option would of been to get an isolated Sprint drive, however experience has taught me the motors on these are far more likely to fail and cause the speed controller to fail, rather than the controller to fail.
