Hi fellow Vesc users,
I am experiencing negative current when in full duty - what is the cause maybe somebody knows?
I am using Ubox 100V 100A board,
Motor is Crystalyte 5305 v2
Battery is 24s LiFePo4
This is my eBike:
Firmware used and vesc tool is 6.0 firmware from https://spintend.com/products/single-ubox-100v-100a-motor-controller-bas...
https://drive.google.com/drive/folders/19hknvr1Skb0jzSKpbtOBUzmIyPnut3Kq...
Here is youtube video demonstrating symptoms: https://youtu.be/oFnaHRKeckI
Has anybody have any suggestion, what can I change so motor will not experience negative current in max duty?
As seen from image current spipes are up to -5A - where is this negative current comming from?
thank you in advance
It seems that negative current is caused by the noisy adc2 which is the brake and adc1 the throttle. Any idea how to smooth out the adc lines? i already have the filter setting on true.
Shield the cable, keep it far away from phase and battery wires and add a ceramic capacitor of for example 10nF or 100nF between GND and ADC2.

I FOUND OUT THE PROBLEM
The cables were two close together so throtle cable was causing noise on break cable. Be carefull guys.
You are welcome!
