B-G431B-ESC1 20vdc Max?

Oddly the on board NFETS are rated 60v, why only 20v input? Can we safely go to +48vdc, if not why? Our motor driven FW the voltage does not go above Vbus.Is FOC space vector 7 phase or 5 phase switched? Thanks

Resolved! I am usinng STM32H7 nucleo board. I want to generate 20KHz pwm wave. How can I control the resolution (that is a value from 0-10000 that corresponds to 0-100%)?

 So I adjusted the ARR and Prescalar values to adjust the pwm frequency(20KHz). Timer Clock is 200MHzI want to change the resolution in the run time with a function. How can I change it?Changing the ARR value will change the resolution?Thanks in adva...
