The Zi Sheng ZS-2D2250M (Bipolar) 2‑phase microstep driver user manual provides safety guidelines, installation steps, wiring, settings, and specifications.
This manual outlines safety precautions, warranty terms, and proper use of the ZS‑2D2250M driver. It warns against operation in wet, flammable or explosive environments, stresses proper grounding, ventilation, and the need for an independent DC power source, and details the one‑year warranty and conditions that void it.
Installation instructions cover storage conditions, mounting requirements, and environmental limits. The guide explains LED status indicators, switch‑based current and pulse/revolution settings, and provides a complete pin assignment table with voltage and impedance specifications for connecting stepper motors and control signals. This manual is written in Chinese.
| Input voltage range | 12‑48 V DC |
