The DMD606 is a stepper‑motor driver developed by Leetro, capable of driving two‑phase or four‑phase hybrid stepper motors with high performance and low cost. It uses a bipolar constant‑current chopper technique, offering higher power output, reduced vibration, and improved positioning accuracy.
The manual covers product features, application ranges, pulse‑mode selection, electrical parameters, pin assignments, microstep and current settings, power‑supply requirements, input signal waveforms, interface circuits, and wiring examples, helping users install, configure, and operate the driver safely. This manual is written in Chinese.
