The 3MD560 is a three‑phase, ultra‑low‑noise microstepping stepper driver from Leadshine, designed for 42‑86 type hybrid stepper motors. It features high‑precision current control, low heat generation, and built‑in protection functions such as over‑voltage, under‑voltage, over‑current, over‑temperature, and short‑circuit protection.
The manual covers product specifications, power‑supply selection, motor compatibility, wiring diagrams, switch‑setting procedures, protection features, typical wiring examples, and a FAQ section that addresses common issues such as power‑indicator behavior, motor heating, and signal timing requirements. This manual is written in Chinese.
| Output current (typical) | 6.0 A |
|---|---|
| Input voltage range | 18‑50 V DC |
| Step pulse frequency | 0‑200 kHz |
| Insulation resistance | 500 MΩ |
| Maximum operating temperature | 70 °C |
| Maximum vibration | 5.9 m/s² |
A red indicator shows that over‑voltage or short‑circuit protection has been triggered and the driver has stopped.
Set switch SW5 to “off” so the driver halves the current about 0.2 s after the pulse train stops, reducing heat by roughly 36 %.
