Ok First with the spindle wires (three of them) if you have them connected incorrectly it will run in reverse so when you first start it check to make sure it is spinning the correct way. If it is wrong just change over any two of the wires.
You can do this at the VFD end on the U:V:W terminals.

You will have to ask cnc4you if the parameters have been set up in the VFD. The Chinese ones quite often need to be set. There is a list of them on the forums some where.
