I am afraid that probably won't work. For a dc servo you need a drive 
that is very fast reacting and operates in four quadrants (forward, fwd 
brake, rev and rev brake). Your drive is designed to hold the motor at a 
steady speed and will be relatively slow reacting. It also probably 
operates in only two quadrants (fwd and reverse).

This link 
<http://www.eetkorea.com/ARTICLES/2000MAY/2000MAY09_AMD_PD_AN.PDF> 
describes the operation of motor drives. It gets a bit technical further 
down but the first few pages describe what is going on.

Mesa do a range of dc motor drives that plug straight into their FPGA cards.
