I’ve got my VESC 4.7 configured with latest firmware (2.8FOC) and I’m having trouble using FOC mode. It will start from as stop very well, but when I apply brakes the motor seems to lose contact with the VESC and the controller doesn’t respond for a moment. There’s a “tick” sound from them motor and then no resistance at all, even though I’m still applying brake from the controller (GT2B). On the bench, I see that the red light is flashing when this happens. I don’t seem to lose connection to the VESC from BLDC Tool, so I don’t think that VESC is rebooting.
Any thoughts on what is going wrong? I love the quiet operation but not enough to lose the brakes! Build thread here pics of BLDC Tool configuration below.
