PROTECTION MECHANISM

Soft Start Protection	Soft start to a neutral position.
Over Voltage Protection	Over 9.0V drive the protection mode and 8.4V return to normal mode.
Low Voltage Protection	Lower than 4.0V, drive the protection mode and 4.5V return to normal mode.
Locked Rotor Protection	Stall in 5 sec, output torque goes down.
Temperature Protection	Overheat 85 degrees C (185 degrees F), drive the protection mode and down 75 degrees C (167 degrees F) return to normal mode.
Lose Control Protection	When losing the transmitter signal, that servo will be back to the neutral position immediately and lock.
