I completely rewired the machine then started on the long journey of programming the VFD. After taking everyone’s advise on different parameters, which got me really close, I finally tweaked the settings where the spindle spins and stops correctly using the onboard commands. If anyone needs them, here are my final parameters. Don’t ask me my logic, because it was all trial and error......mostly error.

I've just run up against an interesting XYS-AT1 issue. I was mains wiring up a new XYS-AT1 I just bought to check it worked and it went bang. Oh dear! I wired as per my other XYS-AT1, from left to right Earth, Neutral, Live. As per the instruction on the board. However see smoke and two blown resistors. I looked at the 'manual' and see its says Earth, live, Neutral?
Can someone tell me the mains wiring terminals they have for this. Thanks

Do you have the manual for it. Also did you have the spindle connected? A picture of the terminals would help

Wired it as my other XYS-AT1 unit and the same as Routercnc did in his video. Got the 2 page manual, looked at it after I had wired it, no load just the three mains wires. The manual says different than the board?! Routercnc mentions in his video a similar issue with another inverter. UK seller has agreed to take it back for refund, annoying as it was £30, guess I know why :)
