I have a deep suspicion that I read something a while back about a setting in the Phaserunner I might have to change to let it see the brake lever signal without it being physically tied to the throttle
Could be a few things. I've found regen on the PhaseRunner to be so problematic that I've given up on it, but others have been using it successfully, so here are some simple things you can check, and maybe you'll be luckier than I have been.
First, you didn't mention the "Throttle fault range" setting, so this might be why you're getting the out-of-range error. Since your throttle start voltage is 1 V, set the fault range to 1 or greater, which will allow the throttle signal to be pulled all the way to zero without faulting.
Second, there's a flag you have to set to enable regen:
Go to Edit -> Edit parameters...
Click the "+"
Scroll down to "Features[04]: Analogue braking Addr 212". Select it and click Add
Check the checkbox and click Done. If it's already checked, then there's some other issue.
Give those a try and post whether that solves your problem.
