Spindle won't start!

Hello,

The spindle on my VMC20 won't start. It stopped in the middle of a program today, and won't restart. I shut everything down and restarted. In MDI it will change from hi to low, but when I try M3 the alarm says "Spindle Motor Overload". Any ideas would be most appreciated. You guys have saved my butt on more than one occasion!

Thanks,
Gamila

Gamila,

My guess is your spindle encoder went out. Same thing happened to my 4020. When I M3'ed the spindle just turned at a very slow rpm no matter what I plugged in for rpm. Do you get a C axis fault???

Good Luck getting back to making chips,
Gitman

Hello Gitman,

No C axis fault. The spindle won't move on it's own at all. I get the overload fault and then an emergency stop fault.
