I think , can you calibrate your ESC ?
And min think is when plug your battery to your craft then motor beeping as a stating beep right ?? After this happening ?
What outputs are you connecting the ESC to on the FC?

If you are using the PM board shown, connect the I/O PMW from the FC to the FMU PWM out on the PM board and the FMU pins pn the PM will be the servo outputs.
Same issue, I have done the things which you had mentioned , enough the beeping is out. Hoping for help to resolve this issue.
When it beeps like that it means the ESC is not get the pulse signal from the FC.
There could be many reasons for this from hardware to setup of the FC.
It’s hard to help with the information you have provided.
