This must be a newbie question, but I haven’t come across a definitive answer yet.
My configuration - Chinese 250W BLDC motor connected to VESC (v2.18 firmware) with Hall sensors supplied by a juicy 22.2V cell pack
PPM input as throttle control and it was verified to cover the full range (0 to 100%) when displayed on BLDC Tool.
Question - When freewheeling downhill, I want to be able to apply a variable amount of braking instead of simple on/off. Is that possible with a PPM throttle? I have tried tuning the “Motor min (regen)” and “Batt min (regen)” current limits already, but it made no difference.
If regen braking cannot do it, are there other methods?
Supplementary info - When I used PID speed control, variable speed propulsion forward and reverse was totally achievable.
