Just looking over the spec's on that board, If you have not already purchased one, I would think the better route to go would be a KB or Baldor style, they can be had off ebay very cheap, even new, they are around the same cost as these units.
If it is a two quadrant drive, which these appear to be, the KB/Baldor have an interlock which prevents going immediately from forward to reverse, a four quadrant drive will have auto reverse and dynamic braking, a 2 quadrant, you have to reverse the motor leads and have some way of preventing immediate reversal.
