biesse rover 316 retrofit

here is the sound of the engine that I can not eliminate in any way (can pwm be increased to 20k is limited), unfortunately linux mint 19.3 does not recognize the 7i92 card at start configuration, ie it throws out an error at startup, although I entered good network parameters, also debian on pc also freezes, I chose the second kernel when starting the computer but the same..after 1-10min jogging..this is so complicated

Sounds like the PWM frequency.

LinuxCNC crashing is not common and probably indicates a hardware issue
with the PC.

if it should be pwm does it can be increased over 20k, in pnconfig it is disabled and fixed? we will see on other axis whan i connect all.
now i am trying to install and enter the pnconfig in mint 19.3, if it doesnt work will change pc as next step, even i think is ok Dell 980, i5 8gb ram nic on board.

The PWM rate is set by the drives, there is nothing on the LinuxCNC side that can change it

which would be the recommendation of the computer?  maybe what freezes the whole linux has to do with the computer, and whether it is acceptable and better to insert ssd hard due to vibration (to note that my computer is in a closet where there is a lot of vibration.

Little progress today (big for me) I found that the freezing of linux is hopefully because of Pc, I replaced Pc today and after an hour nothing bad happened, following Tommy's instructions I got to the point when looking at halscope (but I'm not really clear that straight line..somehow everything goes fast and I can't see what's going on)..to be continued:)
Motor still sounds at high frequency both in operation and while standing. when I turn on all three axes the orchestra will play
