Spindle speed control
Posted: Wed Jan 20, 2021 7:11 pm
Hi,
I was of turning a piece I took a pause. When I restarted the spindle (S800 M4) it started to turn really fast, a way faster that expected. I tried to reduce speed but I have not response. Also when I start the spindle it ramp up really fast mostly no ramp and do the same when it stopped. Previously it was starting slow and increase speed until it reached expected speed. Finally, when I do a M5 to stop the spindle, it acts but after 10 seconds delay.
Just do not understand what happen.
Thank you.
