In 13.5.3. Motions at Drift and Wave Frequency (ansys.com), there are some descriptions of RAO based responses.  If you want to get the 6 DOF motions, please use Structure poistion - actual response.

The actual responses give you the actual LOCATION and/or OREINTATION of a structure's COG.  If the actual response -> global z result at a time step is  -4.9m, it just means that at that time, the COG in the global coordinate system (the origin is at the mean water level) is at -4.9m in the vertical direction.
