VFD Has defantly blown up now!

[routercnc]

I have ordered on from cnc4u as the can get itvto me this week just need to find out why it blew, I noticed a flash come from the plug on the spindle so I assume it was something that end, I found a scorch mark to prove this on the plug

I'll have to try order a spare when I get some cash back in.

Mine did exactly the same as after many years of use the constant movement on the cable and plug caused the pins to have a bit of play in them. It arced and the vfd cut out. I didn't realise what had happened and carried on for a few days. Then it arced again and the vfd was toast this time. It was an expensive Moeller drive at about £350? and had a quality feel to it but they all go the same way if power is interrupted to the motor momentarily.
I bought a Chinese one which blew the moment I switched it on, so swapped it for another and that was has been fine. I direct soldered the cables (remove end cap) added a strain relief collar and added an earth cable inside the housing. Strongly recommend this sort of mod otherwise you will blow another one if the connector can move around when the machine is cutting.

If you go for another plug then make sure it is a good fit on the pins and the cable has strain relief and cannot move around near the plug end.
