Hi guys, got the diff in my Kyosho fixed and did another test-run (one 7S pack), same gearing as before: 84 km/h no-load @ 3.7 V/Cell (but actual RPM limited to 79 km/h, due to max RPM rating of motor). I increased the Current limits from 80 A to 90 A, which resulted in an average peak Current of around 70 A now: roughly 10 A more than I was seeing with the 80 A limits I ran before. It did increase the number of ABS_OVER_CURRENT faults too, compared to the 80 A limits, but it is still very driveable. Motor is a bit at its limits, hitting 82°C after roughly 7 minutes driving (in ~25°C ambient) and needing cool-downs after that. Highest VESC temp recorded in fault codes was 68°C - being mounted exactly above a 70-80°C motor probably isn't helping much to keep it cool.
The last log snip shows 2 Current spikes resulting from holding the brake a bit too long, causing the VESC to switch from braking to reverse. These spikes are larger and more abrupt than the Current build-up resulting from how I typically throttle at acceleration myself. While it is quite fun to play around with on sand/gravel, as you can reverse the motor while the car still has forward momentum and throw up a lot of dust, maybe a braking mode like in conventional hobby ESCs, where the ESC only reverses when "double-tapping" the reverse after stand-still, would be nice in order to reduce mechanical/electrical stress a bit more?
Also, if I set soft RPM limits in the App Config/PPM tab, write them to the VESC, then disconnect/reconnect VESC, the numbers are there after read config, but the Soft RPM limit tick-box is not ticked anymore, as if the soft RPM limit is not enabled. Is this a little bug in the tool?
If there's any changes/settings you want me to test, please let me know Benjamin.
