Should speed up smoothly.

Did you check if there is a voltage fluctuation when 0-10V is connected and servo running?

If yes you need a snubber circuit:

Re: Solidworks for $38.50 a year

Oh bummer.....3 axis milling only....... Uwe, Fusion is just cumbersome. Unnecessary parameters I actually like using the Acorn conversational. It is quick and efficient for simple cuts.

Re: Solidworks for $38.50 a year

The included Shop Floor Programmer is only for 3 axis milling...

Re: Spindle Break In Recomendations

I would do nothing.
If it is cold in the shop do a few minutes warm up with 2000 rpm
When running first time 5000rpm keep an eye on the temperature of the spindle.
