    I think it is HY02D223B.

    The wires seem to be ok. I have nice Igus cables.

    Could you recommend a decent VFD? After this incident I do not want to deal with Chinese stuff any more.

    I have only 230V single phase. I have one fuse in the CNC electronics enclosure and one in the workshop general fuse panel.

    The circled thing exploded violently. I cannot read the part number on it.





    Thank you all
