The angular displacement can be controlled by controlling the number of issued pulses, so as to achieve the purpose of controlling the displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, and its rotation runs step by step at a fixed angle.

A stepper motor is an actuator that converts electrical pulses into angular displacement.
