Description
The stepper driver 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.
This is a high-performance open-loop stepper driver designed for precision motor control in various applications. It supports advanced features and reliable performance for smooth operation.
