Leisai DM556/DM856 stepper driver manual with specifications, wiring, setup, and troubleshooting.
The DM556/DM856 is a digital stepper driver from Leisai that supports 0.1‑5.6 A output current, 20‑50 VDC (DM556) or 20‑80 VDC (DM856) input, and up to 200 kHz pulse frequency. It features low noise, built‑in auto‑tuning, and protection functions such as over‑current, over‑voltage, and motor open detection.
The manual provides a full overview of electrical parameters, mechanical installation, heat‑dissipation methods, interface descriptions, DIP‑switch settings for current and micro‑stepping, power‑supply recommendations, motor selection guidance, typical wiring diagrams, and a troubleshooting section with common fault codes and solutions. This manual is written in Chinese.
