Spindle doesn't stop when emergency button is pushed
« on: August 06, 2008, 12:15:36 AM »
I'm not sure if this is a feature, bug, or misconfiguration. I was jogging around to do some simple cuts, and decided to hit the emergency button. Fortunately, it wasn't an emergency, as the spindle relay stayed engaged. Is there a place to configure this?

Tell us how you have it set up now. Sounds like a wireing/config issue to me.

I'm not sure what information you're looking for, so forgive me if I miss it. It's a small mill (sherline). No speed control, just a relay to control the spindle. Output #1 is configured to Pin 1, and works if I tap spindle toggle on the diagnostics screen. Limit switches are connected to Pins 10, 12, and 13. The stop button is connected to pin 11. All limit switches, and the stop button, work fine. Also, ignoring any inputs, if I hit the reset button, the spindle still doesn't stop. Hope this helps.

Just an FYI- Dual Contact Emergency Stop buttons should ALWAYS be used.  1 of the contacts can be used to stop your controller (Mach) the other set of contacts should be used to power your spindle (either by interrupting the hot lead to the spindle motor).

HTH,

Well, I figured it out My output was reversed. When I ran a program, the fact the spindle turned off instead of on was my clue :) Thanks for the help!

Thats great. What I figured. I have also seen some use a 2 posotion relay one for forward, one for reverse. In that case, it has no choice but to be on even in an estop.  Sids suggestion of a 2 contact e-stop switch is a great one.  ;)
