So I’ve got this problem with my VESCs. If I do a hard acceleration or if the motor needs to do a bigger push, the vesc reboots. After hooking it up to a pc and checking fault codes I get a ABS_OVER_CURRENT for a second and then it the error disappear. The biggest problem is, when this happens the board turn off and I (nearly) goes flying of.
I have tried updating the firmware, adding bigger caps, shorten the wires, removing all bullet-connectors and lowered all motor/battery settings. But nothing changes
The VESC I’m using is the Flipsky Vesc 4.20 from banggood ( https://www.banggood.com/HGLRC-Flipsky-Mini-FSESC4_20-50A-ESC-Based-Upon-VESC-With-Aluminum-Anodized-Heat-Sink-for-Rc-Car-p-1349277.html?rmmds=search&cur_warehouse=CN)
It’s probably the design of the vesc that causes this I would assume, but are there anything you might suspect why this is happening?
I have looked everywhere but haven’t found anything about these kind of huge current spikes
You should put more info (motor, battery, configuration); by the other hand…RC esc to run a board at 50A motor max, and 50 of break…I would by another Esc more capable to manage sudden acceleration, like FocBox, Vesc 6. I also will try setting 35A motor max, 30 motor break, 150 absolute current…If thats works good, it might be time to buy a better Vesc to handle those currents. Wish you the best…
Thank you so much @linsus for shearing the post! I’m gonna test the fix tomorrow and it should work. It have been confirmed by Flipsky that the problem was as described in the post
