Is anyone running one of the 2.2kw spindles below 12000 rpm? I was just wondering if it can go lower without much drawback. If so how much.
Other than the frequency what settings to change?

I have a 2.2kw from linermotion2008 with a hatichi x200 (12000-21000 rpm) and the spindle did not come with any specs about speeds.

Fan or water cooled?

Ive ran mine in the 3,000-4,000 range just fine. it has a ton of TQ.
