I've finally hooked up my G540 to my X2 mill's spindle control board. It works perfectly, except...

When I command the spindle to start, it starts at the programmed speed, with no acceleration time. unfortunately, the X2's motor and controller really prefers to ramp up to speed over a second or so, otherwise the controller sees an overload.

I would like to set up some spindle acceleration. I have adjusted the spindle acceleration under Motor Tuning down to 40 (it was at 60,000), but it has not had any effect.

I suspect that I'm missing a setting somewhere. How do I reduce the spindle's rate of acceleration?
