1. A slight correction.
Old-tech type servos, dc brushed servos like geckodrive 320, of which I have 7, used to dither.
The geckos are not in use anymore.

New ac brushless servos find the position commanded, and lock.
Zero dither.
They are "live" about 0.5 secs, and then lock solid.

Unless you happen to have a constant or no load, a servo has to dither. The drive only knows how much power the motor needs to maintain position, by the motor moving off position.
Modern drives are more accurate and will dither less, but they still need to dither to obtain position. The drive display may tell you it's exactly on position, but an oscilloscope on the encoder will likely tell you otherwise.

I have 2 brands, about 15 total in use and in stock, all are the same.
From 400W / 60V, 750W/220, 2.5 kW/220V.

Who does a 2.5kW 220V servo and drive?
And is that 2.5Kw continuous or peak?
