The Shuangjie SJ-2H090M2/5 manual provides specifications, wiring, setup, and troubleshooting for the two‑phase hybrid stepper motor driver.
The SJ-2H090M2/5 driver is designed for two‑phase hybrid stepper motors up to 5 A per phase. It features high‑frequency chopping, constant‑current drive, optical isolation, eight‑level current adjustment, and selectable micro‑stepping ratios. The driver is used in engraving machines, label printers, packaging equipment, printing machines, and wire‑stripping machines.
The manual covers power supply requirements, input signal connections (CP, DIR, FREE), micro‑stepping and current settings, indicator LEDs, mechanical dimensions, and a detailed FAQ that helps resolve common issues such as direction reversal, wiring for different motor wire counts, step‑angle calculation, and noise or stall problems. This manual is written in Chinese.
