How do you figure that his 50Hz motor is a 2 pole motor, 2850 is quite normal as a 4 Pole motor there are 4 pole motors that run at 3400 to 6000 RPM, the fact that it is 50Hz tells you what it is, I'm sure his motor is something like the attached PDF, this is just one of many different manufactures, that make motors like this
Pn01 is correct=4 he wanted to see RPM in the readout so it needs to be set at the pole count to do this, Pn01=1 will give you a Frequency readout, and that is what he had, See the attachment, you may have found something that is different with your manual settings, but most of what you are saying though is incorrect
Pn08 and Pn09 at 15s are a good starting point for a Lathe a larger number is always better when first trying a new setup, as you can see in what is written with each Parameter, which can be adjusted to suit his machine, without going into Fault mode, which will happen if the settings are to low
I'm not going to waste my time going through the rest, post your manual you may have some different information in your manual that we do not know about
