Centroid Community CNC Support Forum

I’m in the process of converting a small milling milling machine too centroid. I’m using a minarik 4 quadrant drive with PCM isolation board for the 180vdc spindle motor. The speed is straight forward. But not sure how to wire the direction. The manual says short common to Dir terminal. So I assume I only need to use one output realy and assign it as VFD direction? Any help would be appreciated.
