I've used that drive before and I am sure it can do 0-10VDC. I'm not sure about +/- 10VDC with direction reversal.
I think I remember looking at the drive you used before do the positioning and I believe it was much more capable than the Powerflex 40 drive. Didn't you use that other drive along with an encoder for full vector control?? Without an encoder the drive is guessing at where the motor rotor is. I think that positioning with sensorless vector drive will be very difficult unless your positioning requirements are very loose.
