Protection Mechanism
Soft Start Protection Soft start back to 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 immediately be back to the neutral position and locked.
