UL Certified Two Phase Open loop Stepper Drive USR2556

The USR2556 is an upgraded version of the open loop stepper driver launched by Rtelligent, and the product design idea is derived from our experience accumulation in the field of stepper drive over the years. By using a new architecture and algorithm, the new generation of stepper driver effectively reduces the low-speed resonance amplitude of the motor, has a stronger anti-interference ability, while supporting non-inductive rotation detection, phase alarm and other functions, support a variety of pulse command forms, multiple dip settings.
