Any way to stop my vesc6 from doing high current shut offs other than reducing the current? Is it just high battery current or also motor current that will cause this?
I have it programmed to its highest ability. Think it’s 120 or 100 for battery and motor current.

Raise “Absolute Maximum Current” to the highest number it will allow.
Decrease “Fault Stop Time” to 85ms.
The battery current is probably affecting it more than the motor current, I’d guess.
Install the no limits firmware, then I believe you can up the “absolute max current” to where it won’t trigger faults. Had to do that on my 80100 motor.
How safe is it to do these suggestions?
Raising Absolute Max Current to the highest allowed value adds safety, not decrease it.
I don’t use the no limits firmware personally but also I’m not discouraging it. I’ve never found it necessary to remove the limits.
I remember reading somewhere that the non-no limits (default) firmware was limited to 60 battery amps regardless? @Trampa ?
Either way… Raising ABS max current and reducing fault time is not without its own pitfalls.
A soft cut out (ABS Max in firmware) may be preferable to the DRV’s (presumably?) Own safety measures in case of a current spike.
As long as you are legit not exceeding the DRVs abs max, raising the firmwares ABS max shouldn’t be an issue, but ime when it hits the DRVs max things get scary and hurt more than hitting ABS max on the firmware and whatever fault stop time you set.
It’s my opinion that some of the speed tracking can cause overshooting current spikes, and tuning some of the PID values can help reduce current spikes without necessarily needing to reduce current.
Battery amps can never exceed motor amps, so limiting battery amps to protect the ESC is sort of stupid. It’s motor amps that count. Lowering fault stop times is also not very advisable. If you system is tuned in correctly, you should not see an faults. Absolute max should be set to maximum safe current handling of the ESC. It needs to be able to handle and correctly measure currents at that level.
What would be the max setting safely set to for vesc6 in ur mind? If I do full throttle half the time it will cut out
Sorry but I’m watching this thread because I got these
100 amps but it depends on the detection results. If you get cutouts, detection is probably off. Try the latest beta FW for detection and screenshot the detection results. FW 5.3!
You can the go back to the latest stable and do another detection. Another thing you can try is lower or increase the resistance value by ±5%.
First test should be a full throttle acceleration from stand still. Use conservative settings first, then go higher. If 50 motor amps work, detection should be good.
Cutouts can also be motor related, when the stator saturates for example.
Same here I always need to turn off the. On again and again
