Leadshine DM556 Digital Stepper Driver 0.5-5.6A 20-50VDC for Nema 17, Nema 23, Nema 24 Stepper Motor

Leadshine DM556 Digital Stepper Driver 0.5-5.6A 20-50VDC for Nema 17, Nema  23, Nema  24 Stepper Motor

The DM556 stepper drive is designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA17, 23 and 24 hybrid stepper motors. It can be adopted in many industries (CNC machinery, electronics, medical, automation, packaging…) for applications such as CNC routers, mills, plasma, laser cutters, factory assembly lines, vending machines, etc. Its stable performance, simple design, and easy setup features make DM556 suitable for many step & direction control type applications.
