EcoMill 1100v with an SV0436 alarm...

Nov 15, 2023

Been running the spindle at 12k for a week now and running it overnight. Well, this morning I came in to a red light and the SV0436 Alarm. Reset, nothing. Power down and restart. Alarm seems to have gone away. Turn the spindle on and it seems to be fine. Should I be worried?

Thanks in advance!
Yup. It's a servo amplifier alarm.

Did your toolpath have a lot of direction changes in Y?
Yeah, I would imagine so. There's 2.9 million lines of code in this program I'm running. Haha! Spindle is running at 12k for about 30 hours per cycle. I was wondering if the Y axis servo is above the spindle on these so I added a Y to my Loc-Line coolant line and am dumping coolant on the bottom of the spindle to see if that keeps it cooler. (See pic)

We shall see.

Update! 53 hour cycle time, mostly at 12k, with the Y in the coolant line I haven't had that alarm come back!

Simple solution. 😂
