I bought a VESC 4.12 and faced a problem with running it on 12s batteries
my set up is:
190kv sk3 motor; 4 * 3s 5.8a batteries in series bt2b vesc
i made an configuration for my remote, but when im starting my board with 12s batteries, and slightly touch the trigger (10%) motor becomes insane and goes to 100% of max rotational speed on about 3 seconds. the rest 11-100% of trigger are doing nothing. No change of rotation speed. BUT! If i use 9s, 6s, 3s batteries, motor controls by the trigger very accurately - i give 10% throttle - motor spins at 10% of max speed and so on i give 50% throttle, motor gives 50% power
Here is my motor config
Here is my ppm config for gt2b
Interesting part with ppm config that, max pulsw. shows with 100% trigger: 1.85 pulsw. 0% trigger: 1.37 pulsw. min. pulsw. shows with -100% trigger: 0.49 pulsw. Deadband: 0.15 But if i use this values, than with 0% trigger (doing nothing) it shows 63% on display scale. and board going somewhere even if i turn off remote
So, to make display scale show around 50%, i used this walues: max pulsw. 1.93 pulsw. now with 100% trigger scale shows 93% 0% trigger: 1.38 pulsw. min. pulsw. : 0.78 pulsw. Deadband: 0.15
Now, if not touch trigger, motor is not rotating, BUT! if turn remote off(scale moves from 52% to 62%), motor still starts to rotate, so i changed Deadband: 0.25 and it solved the problem.
But how can i change configuration to use 12s batteries with full control motor rotational speed by my remote? am i missing something?
