Looks like today I fired my first VESC…Just don’t understand how and why… Last week I had sometime an ABS_Over_Current Fault, but it was just randomly and didn’t effect my riding. Yesterday I was out for a 20km ride and all was good. For the first 4min of my ride today everything was fine. Than I needed to stop because of traffic. In the moment I wanted to continue driving my master VESC just stoped working. I looked the log file I recorded and there was nothing special about motor or battery current. I didn’t hit max speed or something like this, but the PCB and Mosfet temp already have been around 68 degrees. So first question is, how it can happen that the temp rise up so fast so high without big current flowing? Second question, is there an opportunity to see that the DRV chip is really broken? I opened the cover and couldn’t find anything unusual.
I have a VESC form @esk8 based on HW4.12.
I run dual with motor max 80A, bat max 40A on a 11S4P HG2 battery and 190kV Motor. Gearing is 15/59 on 6.5 inch pneumatics
