Hi,

I have an XSY-AT1 Chinese Unbranded 1.5kW VFD.

I had it going great up until a few days ago, where I am now unable to adjust any of the program settings. The whole display just flashes indefinitely, as opposed to the expected single-digit flashing.

I went through all of the program settings, and only P9 is able to be changed. After checking the manual, this is the password entry box. I've tried the default password of all threes, and it didn't work.

Any ideas?

Cheers!
