This is probably a really dumb question but my forte is not in Electronics

I am trying to wire this permament Magnet mount motor with this drive with 230VAC

I have everything wired up.... except the ground?!?! am I supposed to run this badboy with a rod straight into the earth?!!? Also I would like to have this under PC control eventually I have an encoder but I don't know how to wire it into the Control. Any help would be greatly appreciated! Thanks
