servo operates erroneously.
When an overcurrent flows due to an output short circuit, etc., the overcurrent protection circuit automatically
limits the current to protect the FET.
Remove the cause of the short circuit, etc. before operating the model again.

Overcurrent
protection
When abnormal heating of the FET due to an overload, etc. is detected, the heat protector operates so that
the speed is gradually reduced.
When the FET temperature drops, the heat protector automatically resets. However, remove the cause
of the overheating before operating the model again.
Heat protector
When the Ni-Cd/Ni-MH battery voltage drops, this function limits the motor output current and ensures steering
operation.
After the speed drops, immediately recover the vehicle.
