Yes your thinking is correct. This is why I asked you several posts back to check the Supply voltage. If that pic is the columbo wiring then it's wired Star and 380V so your supply must be 3 phase 380V.
In which case the chinese spindle should work and I'm not going to be able to suggest anything more than have done already ie: check wiring etc and test the 0-10v is working correctly.
