At my current job, we have tons of VFDs (Variable Frequency Drives) manufactured by ABB. We using them for various types of equipment. Recently we had found one that was unable to be turned on, and showed an "internal configuration fault". What a help that was haha!

This is what we found. (on the inverter section of the VFD).

No processing FYI

Nothing beats the smell of melting plastic in the morning.

I'm not familiar with VFDs but it was in the inverter section. That's the extent of my knowledge over these. I previously worked on DC SCRs...Bit different :/

Yep, black magic smoke that makes it work has definitely escaped from that board.

Wow... Did you ever track down the root cause? The last time I saw damage like this was after a lightning strike somehow bypassed our protection. However it happened... ouch!

Nope. We didn't even have any failure alarms. One of our guys found one handheld programmer that are held in the door panel had fallen off (related?). So he put the handheld back in place and it would turn on. We have no clue what could have done it. I personally think it was a freak accident as everything else is fine.

That's incredible! I do have to take what I said, previously, back. A lightning strike is NOT the only time I've seen similar damage. There was also that time when a disgruntled employee broke into a server room of one of my clients' and literally blow-torched the main production server. If only I had my camera with me... bw!

BLOW TORCH!!! HAHAHA! I wish I could have seen that!

I know when we "let people go", they have to be escorted to get their stuff until they leave. Obviously the reason above is why ;)
