The DM856 is a high-performance, fully digital 2-phase stepper driver based on DSP technology,
designed for low-noise and smooth motion in 2-phase or 4-phase motors (NEMA 23, 34).
It operates with a 20-80 VDC input voltage, providing 0.5-5.6A output current and up to 102,400 steps/rev microstepping,
with anti-resonance and automatic idle-current reduction.
Key Specifications & Features
Voltage: 20–80 VDC (Recommended 48VDC)
Current: 0.5 – 5.6A (programmable via DIP switches)
Microstep Resolution: Full-step to 102,400 steps/rev (programmable)
Pulse Frequency: Up to 200 kHz
Modes: PUL/DIR and CW/CCW support
Protection: Over-voltage, over-current, phase-error protections
Technology: 32-bit DSP, automatic parameter configuration
Performance Features
Low Noise & Heating: Advanced 32-bit DSP, providing low-speed smoothness and reduced motor heating.
Anti-Resonance: Nulls mid-range instability for optimum torque.
Multi-Stepping: Allows low-resolution input to produce higher microstep output for smooth movement.
Usage Notes
Wiring: Recommended to use shielded cable for control signals, grounded at one end to reduce interference.
Setup: Use the DamenCNC Manual for detailed pinouts and DIP switch configurations.
Motor Compatibility: Suitable for 2-phase or 4-phase motors with 4, 6, or 8 leads.
