New Build, Aluminium Frame Router/Mill

[Davek0974]

Machines been working well generally, only major issue is random VFD drop-outs with an error code that indicates a short in the motor windings?

Its not done that much work really, i cant believe the spindle is dying already?

The MAJOR issue with this issue is that i haven't wired the VFD fault signal into Mach3 yet so the spindle cuts out and *ping* goes another cutter :(

I need to drag the diagrams out and figure a way to get the fault into Mach, at least that will save my cutters, but surely not the spindle already - this was from Aliexpress, any warranty do you think??

Is there a "good" spindle to replace it with?

Nah doubt it's spindle Dave I'd think it's more like setting that needs tweaking.

Main concern was the error code pointing towards motor phase short, not current overload etc, I'll check the manual but i don't think the short setting would be adjustable?

Might be a long shot but have you checked the motor connections at both ends

Not yet but will pull it apart this weekend.

Been working well, last week did a 5 hour run of parts :)

Today i had one part and the blasted spindle cut out 4 times on me, luckily as i don't trust it i was close enough to e-stop each time and save my cutter.

I can't see any loose wires and its the same vfd message each time :(

Not sure what i can check really?

Ok, pulled it apart and rewired the VFD relay into Mach3, if it faults now it will throw the Cycle-Stop button so at least that will save any more busted tooling.

Not sure what the real cause of the drop-outs is but at least i can walk away from it now.
