Stepper motor drivers take input signals for step and direction (and often signals for other parameters) and output motion on the shaft of the stepper motor. These step and direction signals can come from software running on a PC, a microcontroller, a PLC, or any other device capable of outputting TTL-level signals.

The system diagram above shows the basic configuration of a motion control system using stepper motors. Input signals are fed to the driver, which then translates these inputs into powerful output signals (with the help of a power supply) that drive a stepper motor in the desired fashion.
Our advanced stepper motor drivers are the link between these electrical
signals and stepper motor rotation. Our current driver, part #
SC325MS, is built on the
Allegro A3977SED IC (click here
for more information from Allegro's web site), which offers amazing performance
in a small package. Using the
TTL-level inputs on the SC325MS you can control the step, direction, motor enable,
and level of microstepping (full, 1/2, 1/4, or 1/8 steps).All that is required to form a complete motion control system is the SC325MS stepper motor driver, stepper motor, and power supply. For more information on the specifications and capabilities of the SC325MS please click here.
