Hey so I have been running my setup for about 2 weeks now with probablly about 10 miles on it. And recently my vesc has been reporting “fault_code_drv” I built a custom remote from a wii nunchuck similar to a lot of examples out there with nrf and arduino. I have been having issues with the remote dying on me because of a short I believe and am working to fix it. So i was about 1/2 mile away from my house when the remote died on me, no surprise here. And so I walked it back but there was a hill so I decided to just jump on the board with the battery unplugged and cruise down the hill so I wouldn’t have to walk. I have ridden it before with no power and had no issues.
Could the motor create enough current as a generator to blow my vesc? I know with the old vesc tool you could limit the amount of current from an input, but with the new tool there isn’t an option so I guess I just didn’t think of it. Is it practical to try and replace the drv chip or is there probally other componets blown too?
I am kinda less concerned on fixing it and more on undestanding why this happened so I can avoid it in the future!
Let me know if you have any thoughts. Patrick.
