Ok so I bought a VESC made by flipsky off eBay a week ago and it arrived yesterday. I’ve been having a play with it and plan to use it on an ebike. It was working fine controlling it via up down left right on they keyboard untill suddenly it disconnected when I braked or swithed I to reverse. Upon further inspection I’ve noticed that the entire VESC is disabled for a few seconds and the green led goes off for a few seconds then comes back on again. I’ve tried fiddling with current limit settings but that changed nothing. The only thing that temporarily world was reducing some sort of delay to do with errors. Weirdly no errors showed up in the console and the red led did t blink at all. Same applies to using a throttle knob for control.
My Flipsky 6.6’s dual drive 6380 170kv motors do the same thing. Only during a full battery running 12s FOC it’s an over voltage from regeneration during braking is what I believe is the cause. Once the battery has ran down some the problem goes away. I was suggested to run no Hardware limits version of firmware. Of course run this at your own risk.
I had the same issue here with 2 dual 6.6’s. I was going crazy trying to figure out what I did wrong. Brakes would cut out momentarily after coasting at 41.2v and getting fault code over voltage. Checked and rechecked every connection down to the parallel groups. Interested in a safe workaround. I haven’t explored no hw limits.
Right I’m back now. Seems most people are suggesting over voltage which would make sense as before when it was working, that pack was only at about 38v. I’ll send screen shots and test with a lower voltage at some point this morning.
