STEPPERONLINE Driver 1.8-5.6A 20-50VDC for Nema 23, 24, 34

Product Description :

The Digital Stepper Driver (20–50VDC, 1.8–5.6A) is a high-performance driver designed for Nema 17, 23, and 24 stepper motors in CNC machines, robotics, and automation projects. With advanced motion control algorithms and wide compatibility, it provides smooth operation, high torque output, and excellent reliability in demanding environments.

Supporting step & direction (PUL/DIR) control, this driver can operate at frequencies up to 200kHz, ensuring fast and accurate response. Its anti-resonance feature minimizes vibration, motor heating, and noise, while multi-stepping interpolation produces smoother motion even from low-resolution step signals.

The driver offers 16 selectable microstep resolutions (400–25,600 steps/rev) and 8 selectable output current levels (1.8–5.6A peak, 4.0A RMS) via DIP switches, giving users full flexibility for different motor types and applications. With automatic idle-current reduction and soft-start technology, it ensures energy efficiency and stable performance without startup jolts.

Designed for durability, it includes over-voltage, over-current, and short-circuit protections, while its natural or forced cooling system keeps it running reliably in ambient temperatures of 0–50°C. Weighing only 300g, this compact driver is easy to mount and integrate into CNC and industrial setups.
