Thank you for your answer , I don’t think to use the FW parameter
It is not a good practice to put abs max too high, if it is set to about 50% above max motor current, abs max should not trigger. If this happens the motor parameters are not set optimal. Try to re-run the motor wizzard. Maybe increase max motor current slightly to 130 or 140A but not higher, it could burn your motor windings.
Vesc fw 6.06 runs well in my efoil setup with a 63100 outrunner. I checked my setings, battery current max is 112A, max motor 168A and abs motor max 250A. This is on a makerX 75200 vesc. As a 6384 is smaller these values times 0.8 should be right. Make sure your battery is capable do deliver the current you set.
I just saw you‘re using a 75100 vesc which is designed for 100A (motor) phase current so you might run into thermal limit or burn your FET if you go to high with max current.
My old system had the same hardware and settings, but I never exceeded the 250 amp maximum current. During my sessions, my vesc temperature never exceeded 57 degrees Celsius, even with a 120 amp motor current. I can’t figure out why I’m getting such high spikes. Are there any hardware issues that could be causing me to experience more spikes exceeding the maximum current?
If I increase my battery current to 65 amps or 70 amps and decrease my motor current to 100 amps, will I lose a significant amount of torque, especially during water starts, and will my high peak torque be reduced?
I haven’t enabled “slow abs current” to be set to true, is that necessary?
@sat_be @ludwig_bre @Jezza is it better to put it on true or put abs max on 265 amp ?
No sure, you risk to kill your vesc, see here: Mixed up config for FAULT_CODE_ABS_OVER_CURRENT · Issue #633 · vedderb/bldc · GitHub
So it seems to be better to put 265 amp absolute max …
I don’t understand why I have this high spikes
What is the actual high spike value?
I’m still new, and still learning, so feel free to disregard. I’m having a similar issue with fault code over 250 and the motor cutting out. I was at 200 and raised it to 250 and all was good, then I broke my prop and tried several 3d printed ones. None worked to get me up without cutoff, so just wondering if you have the same prop on the different 6384 you are now using. I’ve given up on 3D printed ones (even after trying sanding butter smooth, epoxy, etc) and ordered a new one. Also, when I go to terminal and type faults, I don’t always get a reported fault the first time I do it. So I wonder if you were getting the fault all along each time it cut out?
I solved my cut-off problem by finally activating the “slow ABS” function; my final settings are as follows:
Battery current 60 amp
Motor current 130 amp
Absolute max 250 amp
Slow ABS : true
