One of our buildings lost 2 drives to a power bump. We are getting a converter phase imbalance and a converter ac under voltage. The fault guide mentions a possible bad rectifier which is what I’m leaning towards. The DC buss is about 460v instead of about 680 like the other cars. I’m wondering if I’m looking in the correct place, and if I am, are they located on the HVIB? I didn’t really tear into the drive too much. Thanks
