# KISS ESC - FAQ ## Possible failures | **Error** | **Solution** | | ----------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | The ESC shows no reaction | Check if battery is connected correctly | | The LED(8) lights up after connecting the power plug but then stays off | Check Signal connection. When using PWM re-calibrate the ESC | | The engine trundles only and does not rotate properly | Check the 3 motor connections (1) on contact (some motor cables are painted and must be stripped) | | The Copter looses power after some time. | The ESC goes into its temperature protection. Reduce the load or give it more cooling. | | The Copter jerks at full speed | 1. the ESC might go to its over-current protection. In this case it reduces its max current to 40A. This reduction can confuse the FC. Please lower the load in this case. | ## Beep/Blinking Codes 1 beep/blink /second = too many DShot errors\ 2 beep/blink /second = disarmed because of ESC signal failsave (a too long period without a valid signal)\ 3 beep/blink /second = disarmed because of a blocked motor or it was not able to get the motor running ## Questions | How can i change motor spin direction? | | How to change motor spin direction is described for each ESC in the ***ESC wiring and connection*** section. If you use a full KISS Setup with KISS FC the easiest way is to change the motor spin direction via the ESC flasher tab in the KISS FC GUI. | | -------------------------------------- | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Do i need to calibrate the ESC? | | ESC calibration is only needed if you use a PWM/oneshot/multishot signal. ESC calibration is described in [KISS ESC - calibration & 3D mode](/kiss-documentation/english-kiss-docu/kiss-esc-common-info/kiss-esc-calibration-and-3d-mode.md). | | Can i use KISS ESC in 3D mode? | | Yes! Please refer to [KISS ESC - calibration & 3D mode](/kiss-documentation/english-kiss-docu/kiss-esc-common-info/kiss-esc-calibration-and-3d-mode.md#3d-mode). If you use the ESC together with a KISS FC the 3D mode can be set via the ESC flasher tab in the KISS FC GUI. | | | | | | | | | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://flyduino.gitbook.io/kiss-documentation/english-kiss-docu/kiss-esc-common-info/kiss-esc-faq.md?ask= ``` The question should be specific, self-contained, and written in natural language.
