In the previous article, we introduced the principle of stepper drivers and the wiring diagram of stepper drivers. Now, let”s follow in the footsteps of the editor to understand how to use and repair stepper drivers.
We have understood the principle and wiring diagram of the stepper driver, but we still do not know how to operate it. Next, taking the ZHH-MC two-phase hybrid stepper motor driver as an example, we will talk about the user manual of the stepper motor driver.
