I can't help but someone would be a hero if they converted and re-published the documents for these machines, so many people struggling;)

Well it's still under guarantee as only bought a few months ago, I cant see a setting causing the device to throw a motor winding short error, but then again, the spindle is new as well, one is reputable and other is chinese.

Its very random though, I have more parts to run tomorrow so will find out if my rewire disturbed anything or its still there, problem is, whichever supplier i contact will likely just blame the other.

Yep, will head that way.

It's a bit like Homer Simpsons' Smoke alarm that goes off all the time to let you know there is no smoke ;)

Will dig a timer out of the junk box.

Nah its a little UC100 usb gizmo on this one.

The machine will need to do a full e-stop as that is the only way to reset the VFD - power cycle it, pressing e-stop puts mach into reset anyway so i might as well just go into reset first.

I'm getting pretty good a restarting code now ;) even down to re-CAMing it and running the missed sections again, always do a re-home first, so far its been ok, its just the wasted tools that were really grinding my nuts - but thats my fault for not thinking of a vfd fault in the first place i guess.

Ok i'll remove the brain and use macro pump, something simple like this?

If IsActive(INPUT1) Then
   DoOEMButton(1021)'put Mach into reset
   MsgBox "VFD Fault - Processing Halted"
   End
End If

Signal conumdrum...

I have the VFD fault relay for the main spindle wired into the e-stop circuit, this is a N/C pair that open on fault, the second VFD is for the aux high-speed spindle but this one has a relay that energises to indicate a no-fault situation and drops out on a fault.

Sounds ok but the the relay being energised on no fault means it only comes on when the VFD is initialised and ready - catch22 as my e-stop will not allow it to come on unless the relay loop is closed :)

Is there a smart way round this - i don't want buttons that have to be held in while it initialises etc, could maybe use a short on-delay timer to short out the VFD relay until a few seconds after power-on but is there a better way????

Found this on the welding bench this afternoon ;)

Should do nicely i think, also fitted the belt covers on the X & Y drives so she's chip-proof now :)

Ok, on the mini-mill i've been having some failures and broken cutters because the vfd keeps dropping out on odd errors, and i did not have the fault relay wired to Mach as i was using it to control the coolant ;)

Anyways, rewired this afternoon and now have the fault relay coming in on an input to Mach, stuck a brain in to monitor it and throw the Stop (1003) button when the fault relay trips on the vfd. It seems to stop Ok so that should at least stop the wasted money in broken tools.

But, even though the input is still triggered (vfd not reset yet) you can still restart the code?

Is there a better way to do full stop and hold it until a reset is done?

Change it to throw the Mach reset button maybe??

That engine would easily pull a cart with 6-8 adults on plus water and coal around a rally field;)

Rail based stuff is a different scaling designation but just as powerful, steam is a wonderful thing:)
