Desperately Need VFD help!

I am new to using a CNC. I have a CNCEST 6040, 4 axis, 1.5kw spindle. I reprogrammed the VFD values. Now the spindle will spin, but it is not moving on any of the axis. It doesn't matter if I'm using manual or computer. As I said I am new to this, Any and all help is appreciated.

What motion (CNC) system is it running?
How is it programmed G.M. code etc?
You should be able to move the axis regardless of the spindle via a MDI move.
Al.

Does it move if the spindle and VFD are turned off?
