Hi all,

Since yesterday I've a problem on my Huanyang vfd, type HY04D023B. It worked for the last year perfectly but now it stopped working and I didn't change anything on my cnc machine.
When I plug in the vfd it starts up like normal and I can control it for a couple of seconds, after that it freezes up. In the couple of seconds I have I managed to do a factory reset (PD013 and put it to 8) but that also didn't help. I fully disconected the vfd and only connected the power supply, but still the same issue. Depending on the moment it freezes the display shows someting else: "r0000", "r0195", ....

Someone an idea what could cause this?

Kind regards,
