And I would definitely go out and find out, but I gave my dad my SuperPID controller I have been using for the last three years, and I have not assembled the new one yet. And I am not going to most likely because I bought a 1.5KW spindle and VFD for mt SO3 XXL that I am slowly assembling.
I guess I could just hook up my spare 611 to the UPS, along with the SO3 and laptop and see what happens when I pull the power on it. The router would be running without a cutting load, but it would probably be close enough for a test.
EDIT: Okay, I did it. Here’s the video. It’s short, but it gets the point across.
