At present, the stepper motor ring distributor has two forms: hardware distributor and software distributor.
The loop distributor of stepper motor refers to the hardware logic circuit that realizes pulse distribution, and the commonly used methods are hardware ring distributor and software loop distributor.
The hardware ring distributor adopts a pure hardware circuit to achieve the purpose of controlling the rotation direction and number of steps of the stepper motor by changing the output pulse sequence of the distributor.
The software ring distributor uses a microprocessor to decode and sequence the input digital signal, and realize the purpose of controlling the rotation direction and number of steps of the stepper motor by changing the timing of the output pulse.
