Gildemeister NEF 480 Retrofit

Many thanks, That at leat means my thinking was right, wich is a relief for me. I will check neutral if there is something funky. If not I‘ll try the second drive and there is simply something wrong with the first one. But I usually assume an error on my side first.

Sorry to read of the problems ----
I have used light bulbs for series resistance in the power feed ( bulbs in series for increased voltage rating and / or parallel for increased current ) when trying to energize problem electronic stuff. Works great for charging up capacitors , tracking down shorted components .and can save fuses or breakers tripping .
Hope it is a easy fix

The mail loop still not working even step checking everything and getting the conformation from Lichuan that I should work with 230V AC.

But the control loop works:



even the encoders are working. Not sure what to with the drives now.

So I checked the tail stock out:



This beast is heavy but it fits:




Then I decided to check the positions for the E stops and am not sure If I should move them. The one towards they are kind of late. The one n the front will trip after the carriage already hat hit the the chuck



and the rear ne will only work without the tailstock:

I got some spare parts for the lube system and now I think it works. I still need to bleed the system and it looks like this would take a while:



but some are already starting oil:

just some more checks and I can reassemble the cross slide. I wonder If I should resurface it to remove some of the marks of former crashes.

hi,

just one thought..

Are you definitly shure that main loop and control loop phase is the same per drive?

Yes, I am also tried connecting them so the same breaker, this didn’t help. Tried the second one too with the same result.
I was thinking about an starting current limiter. But they look so tiny compared to all the vfd‘s i wired up.
