Digital Stepper Driver 0.2-2A 5-24 VDC for NEMA 8, NEMA 11, NEMA16,  NEMA17 Stepper Motor

OK2D4020A is a digital two-phase stepper driver controlled by the latest 32-bit ARM processor. This digital driver has peripheral subdivision, current, and auxiliary function dial codes, which users can freely set according to their needs. Advanced drive control algorithms are written internally to ensure accurate and stable operation of the stepper motor in various speed ranges. Among them, built-in subdivision algorithms can ensure smooth operation of the motor at low speeds; The parameter self-tuning algorithm can adapt to various motors and maximize motor performance; The built-in smoothing algorithm can significantly improve the acceleration and deceleration performance of the motor. In short, this digital drive can meet most applications and is a cost-effective motion control product.
