    In EMC3 for motor 3 I can choose only 4kHz and 31kHz. I'm using IBT-2 that is rated for 25kHz max. Is it safe using 31kHz option? 4kHz is making a lot of noise and I don't like it.

    it should work just fine, but if you are really concerned, then u can get one of those cheap chinese h-bridges on aliexpress ,that can work with 60khz pwm barely makes any noise and runs cool.

    Thanks for your reply. I will try 31kHz then.
