Spindle overloads and drags 200 lb epoxy table 5 inches before I could stop it, it has been awhile since I had to set this up, Everything has been running great for the longest!!. All I did was do a 4 ft extension to my 4 x 10 machine, I did have to move and disconnect all the electronics. That should not have caused a loss of settings, cause I know it was working I stall the spindle more than I hope other are doing, but I need to have it set for the nano second the spindle overloads the damn thing stops!!
all the best

Brian that sounds terrible are you using EX steppers or servos system?
Ex with servos
Did you have the spindle fault enabled or disabled?
If you had it enabled you would have had to do this to your VFD: VFD Parameter Changes - EX Controller Technical Manual
There are dip switches or jumpers on your servo connector board in the control box that allow you to select if you want VFD faults to halt the system…
This only works if you VFD has been programmed with the above link.
Thanks for response Eric I definitely had it programmed to where it would work properly ,spindle would overload it would stop immediately.
I didn’t do anything but take the power off of it unhook all the cables add to 4 ft extension to the machine put it all back together and run it and then in my process the spindle gets stalled a lot , I flatten a lot of irregular shaped epoxy tables which is really hard on the spindle it’s been running so good for so long I forgot where to even start with that setting but now you brought my memory back so it’s a dip switch and VFD settings I’ll get into it.
Thanks
You’ll know if you set it up right or not by simply turning on your control box while leaving the VFD off… If you are perpetually stuck in “drive fault” then you know you set it up. If you can home the machine and use it with the VFD off then you need to enable that feature on the servo board AND make sure your VFD is programmed properly.
Okay when I start the machine up and I don’t turn on the VFD or the spindle box and I try to move it it immediately gives me a drive fault so it will not move at all so that part seems to be set up correctly is there any condition where the spindle would stall and the gantry would continue to move that would cause it to happen? Because that happened the other day, it literally, I watched the spindle stop it’s stalled and then drug that whole slab about 5 in before I get to the emergency stop button and hit it . Maybe it’s something we might want to take a deep dive into if you need any logs or anything the machine may have put out just let me know be glad to help.
A stalled spindle should have thrown a drive fault… That’s odd… You might want to check your spindle programming to make sure it’s on the right option.

can you be more specific … please explain it as you would to a small child..

I linked the VFD programming guide in this post: Spindle overloads and drags 200 lb epoxy table 5 inches before I could stop it - #4 by Eric
Follow those steps again to make sure your VFD is programmed correctly. The output for the VFD can be set to have many different functions, only one of them is correct and is outlined in those instructions
darn, I just went over the vfd settings and my vfd was not listed. I have one of the supplied by cncdepot automation direct gs21-23p0. I know a lot of folks have the old cnc depot package maybe ya’ll could add that to your PDF file.
You’d have to look up the programming guide for that particular VFD and set it up so that the output triggers spindle fault when the VFD is in a fault state. You’d also have to verify the wiring is correct too.
On our VFDs we use the built in output on the VFD in series with the servo drive faults. They’re basically all tied together, so if any motor faults or your VFD faults the system stops.
You probably have this VFD: https://www.automationdirect.com/adc/shopping/catalog/drives_-a-_soft_starters/ac_variable_frequency_drives_(vfd)/general_purpose_vfds/gs21-22p0
Looks like the documentation is there as well.
For the Durapulse GS20 you want 2.13 to be set to 9.
Ok I just checked and sure nuff the setting for 2.13 was 9 so all setting were correct yet I watched the spindle stall and drag the slab, I wonder how this could have happened. I’m very lucky it happen to drag it in the only direction I did not have it blocked in on, else I don’t know might have happened..
Thanks for the setting!
It’s a little hard to say.. I don’t have any experience with those spindles. I know with ours when they stall they open that relay so the controller goes into a fault state, perhaps those durapulse ones work differently…
I can confirm a stalled cncdepot spindle with the GS20 VFD will generate the 9031.
I accidentally buried a RIP Precision 2-1/2 Slab Slayer in 3/4 MDF and stalled the spindle.
