  • ESC always beeping while trying to calibrate (approx. 4 beeps/second)

    Posted by nabil17 on August 10, 2022 at 9:42 am

    Good day all, I am unable to calibrate my ESCs through trasmitter as stated in the ESC’s datasheet. When I turn on the transmitter lowering the throttle and plug the battery, a beep beep beep sound is emitted constantly without any stop, it only stops when I unplug the battery (It continues when I turn off the transmitter). My battery is lipo 3S 4200 mAh.

    Anyone got some ideas?
    The RC, ESC, motor and the RC data after calibration using mission planner used are in the pics attached.
    I have been stuck since 2 months now. PLEASE HELP!
    With regards,
    Nabil. 😀

    I’m not an expert with these but I was able to do some research…based on the steps I found for calibrating these ESCs, you’re supposed to push the throttle all the way up when before you power on the ESC. Could that be the issue? (Again…I’m more of an RTF guy so this is a bit out of my comfort zone…sorry if I’m way off base.)

    F. Programming via Transmitter

    Step 1: Enter program mode
    Switch the transmitter on→Pull the throttle stick to the top position→Switch the ESC on, wait 2 seconds, you will hear two “beep” sounds,
    which denotes that Max. throttle has been confirmed→Hold the throttle stick at the top position, and then wait 2 seconds until you hear tune“♪
    123 ♪ 123”, that means you have entered the transmitter programming mode.

    Step 2: Select program parameters
    Hold the throttle stick on top position, there’re 7 parameters can be set by using your transmitter. You would hear 7 different indicating sounds
    which correspond to 7 different parameters. Pull the throttle stick to the bottom position (full Off throttle) within 2 seconds after you hear the
    correspondent sound will brings you to the correspondent parameter setting status. The indicating sounds will repeat in turn as follow.

    1. “beep-” (a short sound) which indicates the Brake Type

    2. “beep-beep-” (two short sounds) which indicates the Timing Mode

    3. “beep-beep-beep-” (three short sounds) which indicates the Start Force

    4. “beep-beep-beep-beep-” (four short sounds) which indicates the Curve Mode

    5. “beep—–” (a long sound) which indicates the Control Frequency

    6. “beep—–beep-” (a long sound and a short) which indicates the Low-voltage Protection

    7. “beep—–beep-beep-” (a long sound and two short) which indicates the Cutoff Mode

    8. “beep—–beep-beep-beep-” (a long sound and three short) which indicates the Rotation Direction

    Step 3: Select program values
    After entering parameter setting status, hold the throttle stick on the bottom position, you will be led to the repeat selection of that parameter
    setting status. Each sound likes 4 short sounds and one long sound (1 long sound=5short sounds), and by that analogy. After some sound, pull the
    throttle stick to the top position in 2 seconds, after you hear a tune “♪321 ♪3 2 1”, which means the correspondent value has been chosen and
    saved. Hold the stick on the top position, return to the second step and continue programming.

    Step 4: Exit program
    Pull the throttle stick to the bottom position within 2 seconds and hold on after saving parameters, until you hear a tune “beep—- beep- beepbeep- ♪ 1 2 3”. Set the Min. Throttle at this moment and exit program and operate as normal.(beep—-means Loading parameter. beep- beepbeep-means numbers of cells and ♪1 2 3 means ready. )

    Restore Factory settings
    To restore Factory settings, pull the throttle stick to the bottom position (full Off throttle ) within 1s after entering program mode (Step 1)→Pull
    the throttle stick to the top position within 2s, then you will hear a tune, which means that the factory settings have been restored. Pull the
    throttle stick to the bottom position within 2s, the ESC is ready with factory settings.
    If the Bidiretional mode is chosen, the Minimum Throttle actually means Middle Throttle position. Factory settings can be restored under
    Bidirectional mode.

    @noahgolly This sounds like something in your wheelhouse…any ideas as to what’s going on here?
