To enter a 50 Hz square wave signal output terminals, and high pulse duration control signal cycle time can control the speed and reversing stall. A high pulse duration corresponds to a speed. High for 1 ms to 1.5 ms, steering gear forward (1 ms forward the fastest, the slower the closer to 1.5 ms, 1.5 ms servo stall), high servo reverse 1.5 ms to 2 ms (1.5 ms servo stall, the closer the faster the speed of the reversal of 2 ms, 2 ms, the fastest reversal).The steering gear with a median adjustment potentiometer (open shell to pry the circuit board to see), debugging can be high pulse is set at 1.5 ms to observe the steering gear stall, if you stop and turn on the regulation potentiometer until the stall so far, so the zero.
