I want to controll brushless motor through ESC.
I have used Arduino Uno. I output pulses with PWM.

How many frequency should be output to following ESC ?

Simon-12A

and How can I check the frequency to be output to the ESC?

thanks.

Usually just one.

How can I check the frequency to be output to the ESC?

Ask the manufacturer.

That ESC will usually work with a PWM frequency of anywhere from the servo standard of 50Hz up to about 400Hz. Since it still uses a pulse width of roughly 0.7-2.3 ms then around 400Hz is the practical limit.

If you are driving it with an Arduino then you can control the PWM frequency you are using, though note that the standard analogWrite() frequency (typically approx 500Hz) is almost certainly too fast.
