DM860H Digital Stepper Motor Driver 18-80VAC/24-110VDC 2.4-7.2A

Description

The DM860H is a robust DSP‑driven hybrid stepper driver optimized for two‑phase and four‑phase NEMA 23–34 motors. It accepts 18–80 VAC or 24–110 VDC, delivers 2.4–7.2 A peak output current via SW1–SW3, and offers 400–25,600 steps/rev microstepping via SW5–SW8. Key functions include auto‑tuning/self‑test, anti‑resonance smoothing to eliminate mid‑speed instability, soft‑start to prevent motor kick, and idle‑current reduction for lower heat.
