Servo motor control typically requires a time base pulse of approximately 20ms. The high-level portion of this pulse generally consists of the angle control pulse within the range of 0.5ms to 2.5ms, with a total interval of 2ms. Taking a 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;
