The Chinese spindles are pre wired in delta, can't be changed so you are OK there.
problem with these inverter manuals is everyone has different meanings and descriptions. i also feel that there is a competetion going on between these people to see who can write the most obtuse manual.

Siemens are close to the top.

Local company to me wanted to put a big 15 Kw inverter in a box with everything set and just required a remote control 100 feet away with stop and start buttons, it's called 3 wire control. Anyway their electrician couldn't understand how to do it so they sent it to the local rewinders, they called me in as I used to fit literally 100's of inverters at one time.

The book was A4 and 40 mm thick, I couldn't find anything about 3 wire operation or remote buttons or control, even got the manual up on line to search it. Soooo rang Siemens in London, had to ring them 3 times because they didn't know how and never returned calls.

In the end we got a returned call from Siemens in Germany who explained what parameters needed to be set and it worked I then looked in the book at these parameters and nowhere did it hint that altering these would enable 3 wire so i asked why not a simple diagram to show the 3 wire operation.

I was told no one uses 3 wire operation any more, they switch incoming mains on contactors !!!!!!!!!!!!!!!

[edit]

Routercnc,
Sorry what I should have done was nip in the workshop and look at what settings were on my router, I have the air cooled version and Fuji inverter but the settings will be roughly the same. I know mine works OK as the Fuji tech set it up when it was delivered.

Sorry.
