Protection Mechanisms

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.
