The control of the steering gear generally requires a time base pulse of about 20ms. The high level part of the pulse is usually a part of the angle control pulse in the 0.5ms-2.5ms range, with a total interval of 2ms. Taking 180 degree angle servo as an example, the corresponding control relation is like this:
0.5ms--------------0 degree;
1.0ms------------45 degree;
1.5ms------------90 degree;
2.0ms-----------135 degree;
2.5ms-----------180 degree;
360 degree refitting steering gear: the actual speed reducer is infinitely variable, which can control speed and direction. There is no 0-360 degree angle control function. The control mode is the same as the control signal of the general steering gear. It is a very suitable source of power for the alteration of the tile force. When the high level is 1 milliseconds ~1.5 milliseconds, the steering engine is turning forward (1 milliseconds with the fastest rotation speed, the closer to 1.5 milliseconds and 1.5 milliseconds at the helm), and the high level is 1.5 milliseconds ~2 milliseconds reversal (1.5 milliseconds, the steering gear is stopped, the faster the reverse of 2 milliseconds the faster, the fastest speed reversal at 2 milliseconds).
