Stepper motor driveris an actuator which can transform pulse signal into angular displacement signal, Stepper drivers drive stepper motors to rotate at an angle called step angle in the set direction when receiving a pulse signal. The motor speed is up to the pulse frequency given from the controller, and the displacement is decided on the pulse quantity given from the controller. Stepper system consists of a stepper motor and a stepper driver. Performance of a stepper system is not only up to the motor, but also depends on the stepper driver.
