However, I have found that this is not the case when i'm trying to go slow downhill, and when I apply a brake force until it hits maximum, I will not be able to modulate the braking anymore and the brake force remains at maximum. It is only when I release the trigger close to neutral when the VESC totally lets go and starts to coast downhill.
This is quite concerning as sometimes when you are trying to navigate traffic going downhill, not having the ability to modulate braking and speed becomes a little concerning.
I have tried to make the following adjustments in BLDC Tool but nothing seems to solve the problem:
1. Varying motor and battery current limits and absolute max settings
2. Bringing max ERPM at full brake down to 0 (not recommended but had to try)
3. Varying PPM pulsewidth limits
Would anybody be able to point me in another direction to investigate how I'm able to continue modulating the braking after getting to max brake? Any advise would be appreciated. I'm not sure if it is a voltage issue or the fact that my motor is sensorless, it does not look like either of these could be the cause, but I could be wrong.
I've posted a image file of the realtime capture of data from the VESC on a flat ground going into full brake and releasing pulsewidth into neutral. The jump from full brake to no brake is seen in the circled portion.
My battery/motor setup is as below:
Motor: 5065 Sensorless 190kv
Battery Setup: 9S2P Li-ion
Would appreciate any advice! Thanks!
