The control of the steering gear generally requires a time base pulse of about 20ms. The high level part of the pulse is generally the angle control pulse part in the range of 0.5ms-2.5ms, and the total interval is 2ms. Taking the 180-degree angle servo as an example, the corresponding control relationship is as follows:

  • 0.5ms———— 0 degrees;
  • 1.0ms———— 45 degrees;
  • 1.5ms———— 90 degrees;
  • 2.0ms———— 135 degrees;
  • 2.5ms———— 180 degrees;
