From Makers Electronics's description

DM860H Digital Stepper Motor Driver 18-80VAC/24-110VDC 2.4-7.2A 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. Features Peak current 2.4–7.2 A, selectable in eight levels via SW1–SW3. Voltage supply 18–80 VAC or 24–110 VDC without additional wiring modes. Microstepping from 400 to 25,600 steps/rev via SW5–SW8. Auto‑tuning/self‑test for quick setup and optimal performance. Anti‑resonance filtering for smooth mid‑speed torque and low vibration. Soft‑start prevents motor “jump” at power‑on. Idle‑current reduction to 50 % after ~1 s inactivity. Opto‑isolated step/direction inputs (PUL/DIR) with fixed CW/CCW handling. Comprehensive protections: over‑voltage, under‑voltage, over‑current, and motor‑open/short. Specifications Parameter Value Model DM860H Driver Type DSP‑controlled two‑phase hybrid stepper driver Supported Models NEMA 23–34 hybrid stepper motors Input Voltage 18–80 VAC / 24–110 VDC Peak Output Current 2.4–7.2 A Microstep Resolution 400–25,600 steps/rev Pulse Frequency Up to 200 kHz Control Modes Fixed PUL/DIR step & direction Soft‑Start Yes Anti‑Resonance Yes Idle‑Current Reduction 50 % after ~1 s inactivity Protections Over‑voltage, under‑voltage, over‑current, motor‑open/short Operating Temp Range 0 °C – 50 °C Storage Temp Range –20 °C – 80 °C PINOUT Applications Drives NEMA 23–34 motors in CNC routers, laser cutters, and electromechanical actuators. Ideal for pick‑and‑place machines, XY tables, and robotics requiring smooth torque. Suited for automation, packaging, and precision instrumentation.
