The servo motor itself has the function of emitting pulses, and the servo mainly relies on pulses for positioning. Every time the servo motor rotates an angle, it will emit a corresponding number of pulses, forming a response or closed loop with the pulses received by the servo motor. In this way, the system will know how many pulses have been sent to the servo motor and how many pulses have been received back. In this way, the rotation of the motor can be accurately controlled to achieve precise positioning, which can reach 0.001mm.
