People, I solved the problem. I add a new line iin my config.g a PanelDue port: M575 P1 S1 B57600. Nos its Works fine.

@alankilian, @Phaedrux and @dc42. I solved the problem, thanks for yor tips and support.

I discovered the electronic component that was damaged, it was a 47K resistor (R80) of the voltage divider (PWR_FAIL_DET2).

I replaced the resistor with another resistor and my machine returned to normal!

@Phaedrux :
I solved my problem, I add the command M501 at the end of my config.g.

I use in my Duet2WiFi the firmware version 3, RepRapFirmware Configuration Tool v2.1.8.

I made the autotune in the BED and I add the Heater model parameters at the config-override.g.

Now it's working well, thanks for the support.
