Question: Internal Reset Error After Throttle Release on Golden Motor BLDC with Kelly Controller

[youganghyeon]

Hello, I’m using a Golden Motor BLDC 10kW (HPM series) motor with a Kelly KLS 72150N controller.


When running the motor under no-load conditions, it spins up to maximum RPM without any issues.


However, when I suddenly release the throttle, the motor briefly stops and then continues to rotate in the same direction for about 1–2 turns.
Immediately after that, the controller emits a 3-2 beep code, indicating an Internal Reset Error.


I’m not sure why this is happening.
Has anyone experienced something similar or does anyone have suggestions on how to resolve it?


Any help would be greatly appreciated.
