incoming voltage to DC link to low drive system 2.connector board 1

good idea to not mention brand, model or anything helpful... we can just try to guess...

Well that looks like an ABB s4c or s4c+ pendant, so I've moved this thread into the ABB subforum.

But really, more information would be useful. We are not mind readers.

There is a list of things to check that accompany that error, check those.

It may be a safety circuit issue depending on how Drive System 2 is wired, especially if a non-ABB configuration.

Could also be as simple as the transformer breaker was bumped in an aux cabinet. The possibilities are plenty without more detail.

terrible picture but i think the top error is mains missing which means you have a phase out

I had the same issue last week I found it be loose connection

I had the same error loose wiring from the beaker board to rectifier

I Think it could be problem in +/-15 V ( which is considered a Dc_LINK )
