Ok so went for an hour of riding to test out everything. Everything seemed fine until I was going at max speed I guess 23+ plus and I suddenly hit the brakes because i saw someone crossing the street and the board braked for 0.1 seconds and i felt it stopped braking. I tried to brake again and it didn’t do anything, after like 3 seconds i tried it again and it braked but this time i wen easy on the throttle while braking. It was a very scary experience. Curious to know what causes that. Any help will be appreciated as I need to fix that…let me know what do you guys think. My specs/screenshot of current set up are on the first post. Using exertion space cell 3, exertion standard VESC and 6372 motor spec r.
your max input voltage is probably too low, a voltage spike may cause the vesc to shut down…
Maximum Input Voltage 60V
is this mono or dual?
if its mono, i would change current limits:
Motor Max 60AMotor Min REGEN -20 (this really depends on your weight & preferences, maybe go down from -40 in increments of 5 & test it)
Batt MAX 40A (slightly higher is ok, but eventually you’ll blow a fuse, go up in 1A increments & test it)
Batt Min REGEN -12 (this is probably correct, it’s always best to try to keep Motor Min Regen & Batt Min REGEN as close as possible)
Can you check the advanced tab as well? There’s a setting (Max Current Ramp Step) in there that multiplies itself by 10 every time you write config on the motor config tab (software glitch). It should be .04 at default. Not sure if this affects your braking, but I’m sure it’s not great to leave at 10x/100x/1000x/etc the normal value. See here:
It could be that the battery regen braking setting you have is incompatible with the amount of current the battery could handle. Try reducing the regen current.
So I input all the settings including the ones from @onloop and I am bench testing it. The board is at 100% and when i give full throttle and instantly try to brake it doesn’t do anything. Going slower and braking works just fine…any ideas?
connect VESC and check the display box in the above picture. Full throttle and you’ll get the max pulsewidth, min throttle and you’ll get the min pulsewidth. Put the values in the respective boxes and apply. Make sure to switch to ppm only!
