Please help. Can't work with PWM on ESC32v3

[Masa]

Hi, all
I'm able to connect to the AQ ECU and change RPM with the interface using an FTDI.
But I can't work with PWM from Arduino uno.
Using motor is Hyperion VP Z2209-30.
I'm powering the ESC via 5v of Arduino connected to PC.
I tried a lot of width of frequency, but It did'nt work
I can't understand appropriate frequency of PWM and duty.
Please need your help i do not understand the problem here.

These are parameter in ESC

BAUD_RATE = 230400 baud

SERVO_SCALE = 360.0 deg

Try and change pwm max period to 20000 to allow 50 hz pwm
