The working principle of a pulse driver can be simply summarized in three steps: Receiving commands, converting pulses, and outputting control signals. Each step will be explained in detail below.
Receiving Commands: The pulse driver controls the motor by receiving commands. Commands can be transmitted via various methods such as serial ports, parallel ports, and network communication. Different devices have different interfaces and communication protocols; the appropriate communication method should be selected based on the specific situation.
Converting Pulses: After receiving the command, the pulse driver needs to convert the digital signal into a pulse signal. The pulse driver generates the required pulse signal through internal counters and timers. Different devices have different pulse types and frequency ranges.
Outputting Control Signals: Finally, the pulse driver converts the required pulse signal into a voltage signal that the motor can recognize, and controls the motor's rotation and stop through the output signal. Generally, the pulse driver achieves single-step, full-step, or micro-step control by controlling the high and low levels of the pulses.
