The DM870 stepper drive is designed to power 2 phase(1.8°) or 4-phase(0.9°) NEMA23, 24 and 34 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 excellent performance, simple design, and easy setup features make DM870 ideal for many step & direction control type applications.
Key Features:
