My ESC does not generate a beep when powered up.

Generally speaking, the ESC shall generate a long beep from its buzzer when it is:

  • Properly powered up
  • Properly receiving PWM signal

Under a normal procedure, we recommend NOT to check the PWM signal box before you connect the stand to the power source:

Once the ESC is powered up, you shall hear the ESC doing a constant short beep. When checking the box, the ESC shall generate a long beep to notify it receives a signal. If your ESC is still doing constant short beep after checking the ESC control box in the GUI, please follow this guideline:

  • First of all, check the brand and the made of your ESC and confirm if your ESC has an embedded BEC (Battery Elimination Circuit). The BEC is a voltage regulator and provides 5 V for the internal use of the signal processing. In case that your ESC does not have an BEC built-in, you must provide an external 5V to your ESC.
  • There is a 5 V port on the circuit or on the Power and Control Console, you may use those ports to power up the control section of your ESC.
  • For the newer version of the Series 1585, there is also the extra 5 V port on the circuit for the non-BEC ESC. If you are using the old version of Series 1585, you may need to use an external power supply 5 V to power up the control section of the ESC.
  • If the problem persists, or your ESC has a built-in BEC, but your ESC is still not making a long beep after checking the box in the GUI. Please check your ESC’s PWM signal input requirements, the PWM signal output from the thrust stand uses standard 50 Hz.
  • Your ESC may also require a calibration at first use, please make sure that you have properly followed the procedure proposed by the manufacturer.
  • Please check if your ESC is being powered with the correct voltage (HV or LV).
  • If your problem still persists, please contact support@tytorobotics.com and indicate the following information:
  • Subject: ESC not receiving signal
  • Include the made and the model of your ESC
  • The voltage that you are using
  • A photo of the wire connection of your ESC
