I'm Excited to use my new VFD. although I'm stuck at something that might be very simple.
there is no ground wire on the UVW side of my VFD. the manual says this for the grounding section.

3.2.2.6 : Grounding Terminal : " Do not share the grounding terminal with zero line of power supply."

i have no idea what that means so im scared to share the ground thats going in on my single phase power side.

i have some images. any help would be appreciated. Thanks!

You should ground the frame of the motor to the service ground provided, this should be the same as the earth terminal on the power entry point.
The +/PB is a brake resistor terminal.

In this case the ( 2 ) Grounds can connect to the same Ground Terminal, or if you can find a place on the Heat sink of the VFD that has a place to mount the Ground wire, this can even be on the mounting foot of the VFD, just make sure it has a good contact, if you did it this way, remove paint or any anodizing from the Heat sink, set your parameters correct for your spindle
