Hey, guys.
I have a 311 that runs fine on INS, but on NOR, it begins to accelerate and then dies after a few inches. Indications are a "DC link UV." Bus voltage looks fine. I've read there's a parameter at 4-3-1-7 that will allow me to change the threshold, but I can't see it. I can go 4-3-1, and then step through a variety of options. None of those options, however, allow me to change the threshold for low bus voltage. Thoughts?
