Just wanted to let you guys know, the stuff regarding max duty cycle is on Vedder and My radar.
Vedder has pretty good theory on what is going on, he made the maximum duty cycle limit work better which is somewhat ironic. Basically before as you approached max duty it wouldn’t correctly prioritize Q-axis current (the current that makes torque) over D-axis current (no torque). Now it does this more efficiently which is good, the problem is it causes a more abrubdt feeling torque loss when the limit is come up against and can cause oscillations with some setups since it is a rapid change. The solution is to soften the change as per the setting @Trampa is pointing to.
I’ve talked with Ben about the best ways to add this into the wizard for next release. It does cause a slight decrease in top speed power in the last 5% so people on e-bike or expert users and other applications might not want this limit imposed without being informed.
