VBL1650 - RoborunPlus PC Utility - Regen

I downloaded the RoborunPlus PC utility (looks very nice btw). I didn\'t see any settings for adjusting the regenerative braking. I\'m not sure if this is an analog or digital input to start regen or if regen happens after a certain percent of deceleration (if so I didn\'t find any adjustment settings for this in RoborunPlus).
