On my second machine I recently installed the EX with servos, I do mostly slab flattening with that one and unfortunately the spindle will get stalled. It happened the other day and the gantry continued to move breaking the bit. Where can I find the setting for this and it there a safe way to test this short of stalling the spindle?
Hey Brian - do you have the VFD’s output setup right for that one? It should go to a failure mode, and turn off the machine on an error like that.
It is definitely not working, I have the vfd turned off and I can jog all over the place.
I also set the dip switch 4 to on and then off, and checked the wizard and it is set to warn on vfd faults. I’m about to start over on trouble shooting , I tend to miss some steps some times…
this machine has the Automation direct gs20 VFD in it so the internal setting may be wrong, what do you think and where would I find the right ones…
I think what’s going on here is that you don’t have the relay output on the VFD programmed or wired correctly (or both)
That DuraPulse GS20 has good documentation (And a nice Windows app!) to help you configure it.
What we do on our VFDs is configure them so that the relay is closed ONLY when the VFD is in a “good” state. (IE powered on and not faulted) that way if you forget to turn it on, or it stalls the relay opens and the EX goes into a fault state.
I’d double check our schematics for EX to see how we wire it (it’s very simple, just two wires into the VFD) and then check your wiring on that durapulse.
If that looks good I’d configure the parameters on that VFD accordingly.
I have directions for it on my page:

It’s the GS10, but it is likely the same! I set parameter P02.13 from 11 (Malfunction) to 9 (Drive is Ready):
damn, 02.13 is already set to 9
That means it is (probably) something with the hardware or dip switches
Ok I just talked to Alex at CNC Depot and he got me sorted out. here is a pic.
Early during the install the spindle would not spin up and I saw that moving the wire from r10 to r1 made it work, well it also disable what I needed so we put it back and now it is working. thanks to all that helped…

So what did you have to change, if anything, in CNC12 so that the spindle spins as it should and it shuts down via VFD on fault?
