I’m on my second blown (DRV error) slave VESC and have no idea what is going on. Bought two motors and VESCs from DIY. Ran BLDC detection on each, etc. Followed this set of instructions on configuring CAN bus. Everything seemed fine. The board ran great, for a half mile until I started going uphill it started stuttering and I noticed that only one wheel was getting power.
Turns out the slave VESC had a DRV error. I couldn’t find any obvious visible issues with the VESC and I wasn’t exactly sure why it blew, but I thought I probably hadn’t insulated the leads well enough. Ordered another one (this time with the warranty) which took a few weeks to receive. In the meantime, I removed the second motor and put at least 100 miles on the board with a single motor/VESC. Zero problems. Up/down hills, all over the place.
Received the new VESC. Carefully ran through motor detection and everything. Over-insulated every lead and used CAN bus to connect the VESCs. This time, I got about 2 miles on it before I ran into the same problem, again which I noticed again while going uphill. Sure enough, same DRV error.
I’m not even sure where to start looking or what could be causing this. Any ideas?
