Hello Everyone,
This is my first post.
I am trying to select a 3 phase motor for a high speed spindle, and after reviewing some foreign models, I noticed that they often give a S1 and S6 rating on their power curve.

Does anyone here know how to set the spindle up to run at S6? Do you have to adjust the voltage? How do you differentiate S1 from S6?


I hope someone has had some experience with this - thanks.
