    Hi, I have problem with traction loss motor (motor 3 in SMC3). In LFS traction loss is working for about 15 seconds and after that motor is not working at all. In SMC3 then I use Sine Mode it is working for about 2,5 full sine waves and shuts off too like hiting Max limits (but it isn't). Motor and BTS temperature is ok. What can I do with this?

    USB isn't disconnecting. because motor 1 and 2 are keeping their position.
    Here is a screen shot what is happening in SMC3 and settings.

    Kp looks unusually high, so does Fpwm.

    Yeah, with 4kHz and 600 Kp it works fine, but 4kHz noise is unpleasant. For motor 3 it is only 4kHz or 31kHz :/
