3 phase is a completely different branch of electrical work to domestic 220v single phase. And probably different again to your problem which is probably inside a box that nobody untrained will open.
Probably already covered by the 2 you have had in, and the fact you have error messages at the inverter but learn and understand exactly what the error messages are telling you, also photograph them / write them down.
Then:-
1st highlighted by the post on here re dust filter, take out anything between wall socket and lathe remote switch, extension leads anything....
2nd Unplug it from it's socket and try it in another socket, while trying something like a heater or kettle that has high current draw in the original socket.
3rd Take the plug apart check it is well wired no scorch marks and why not put a new fuse in.
4th take the cover off (WHILE UNPLUGED) check the wiring connection from 220v into inverter looking for scorch marks or any indication of a bad connection.
5th Do the same visual / prodding checks between inverter and motor
Between steps 3 and 5 you will also learn how to remove the inverter, if it is not yet working you need to take the inverter to a specialist with the error messages, I found a local industrial electric motor repair facility was able to do all the required tests and fixes when I had a similar problem on a 3phase bandsaw. I took in the inverter and motor for that, much easier than taking the bandsaw which is just bearings and pulleys anyway.
