Hi, im running a Maytech vesc 6, Fw 5.1, using FOC. When I run the motor or any detection >10A the usb connection with the vesc from the VESC tool (Win 10) stops with the error "Serial port error, a device attached to the system is not functioning". When I run a detection with low amps (flux linkage or hall sensors) no error / result is returned. Has happened with multiple cables / computers, and im unsure what could be causing it. No faults show up in the terminal. Motor settings:
(the motor is a large ebike motor)
Any help is appreciated
thanks
This is non original hardware, not a VESC. It's hard to tell what is going on there. Probably the ESC is shutting down due to under voltage or over voltage or another event that causes device shutdown. The shutdown will delete the fault, so you can not see the fault code.
