Description

The DM556 Stepper Motor Driver is a high-performance, fully digital 2-phase stepper motor driver utilizing advanced 32-bit DSP technology with a sophisticated control algorithm. Designed for driving 2-phase hybrid stepper motors (e.g., NEMA 17, 23, 34 with 42mm to 86mm frame sizes), it operates on a 20-50V DC input voltage (typically 24-48V recommended) and delivers a peak current of up to 5.6A (1.8-5.6A adjustable). Its anti-resonance feature optimizes torque and eliminates mid-range instability, while motor auto-identification and parameter auto-configuration ensure optimal performance with various motors, simplifying setup. The driver supports microstepping up to 1/128 steps (15 selectable resolutions from 400 to 25,600 steps/rev), configurable via DIP switches, alongside eight current settings for fine-tuned control.

Key features include extra-smooth movement, low noise, and reduced motor heating, making it ideal for applications requiring high precision and quiet operation, such as CNC machines, engraving machines, laser cutters, and pick-and-place devices. It supports PUL/DIR or CW/CCW control modes, with a pulse input frequency up to 200kHz, and includes optical isolation for strong anti-interference ability. Built-in protections—over-voltage (triggers at 52±1V), over-current (exceeds 16A), and phase error—are indicated by a red LED flashing 1-4 times every 3 seconds, prioritizing the highest-level fault. An automatic idle-current reduction (50% after 0.4 seconds, switchable via SW4) minimizes heat during standstill. For Arduino use, connect PUL+ to a digital pin (e.g., D3), DIR+ to D2, ENA+ to D4, with all negatives to ground, and power with a 24-36V supply. Use the AccelStepper library for advanced motion control. This RoHS-compliant driver, weighing approximately 300g, operates from -10°C to +45°C (or up to +85°C in some specs) and requires a heatsink for continuous high-current use. Note: Never connect or disconnect the motor while powered, and adjust DIP switches only when off.
