An Electronic Speed Controller (ESC) is a device used in electric-powered drones to regulate the speed of the electric motor. It serves as an intermediary between the motor and the power source, interpreting signals from the Aerial Electronics Module.
Possible Causes:
Corrosion or bad connection to and from ESC
ESC went bad
The propulsion motor connected to the ESC failure
Troubleshooting Steps:
Check for corrosion on the wires going to and from the ESC
Verify there is no update for the drone or ESC
Replace the ESC
If you want to confirm that the ESC is faulty, you can swap it with another one on the drone and check if the error message changes for the ESC #
In rare cases, the propulsion motor may be the cause of the issue
Swapping the ESC with another one on the drone can help narrow down the problem.
Important Note: If you replace the ESC, a mini update will occur for the specific part. Return to the home screen and wait for a pop-up to appear in the center. It will display a message such as "Incompatible Firmware."
Prevention
Keeping the ESC free from chemical residues and dirt can aid in heat dissipation, prolonging its lifespan and helping to prevent unexpected failures.
Using props that aren't chipped, bent, warped, or loose ensures that the motors don’t have to work harder than necessary.
