Micro-Step motor driver 5.6A 20-80VDC DSP

 133.00EUR - 145.00EUR 

A versatility fully digital stepping drive based on a DSP with advanced control algorithm is the next generation of digital stepping motor controls. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. Motor auto-identification and parameter auto-configuration technology offers optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drives in the markets. Its unique features make the DM856 an ideal solution for applications that require low-speed smoothness.

Owing to its higher performance DSP, driven motors can achieve much higher speed (above 3000RPM) than that of the older driver offering servo-like performances.


  • Anti-Resonance, provides optimum torque and nulls mid-range instability 
  • Motor auto-identification and parameter auto-configuration technology, offers optimum responses with different motors 
  • Multi-Stepping allows a low resolution step input to produce a higher microstep output for smooth system performance 
  • Microstep resolutions programmable, from full-step to 102,400 steps/rev 
  • Supply voltage up to +80 VDC 
  • Output current programmable, from 0.5A to 5.6A 
  • Pulse input frequency up to 200 KHz 
  • TTL compatible and optically isolated input 
  • Automatic idle-current reduction 
  • Suitable for 2-phase and 4-phase motors 
  • Support PUL/DIR and CW/CCW modes 
  • Over-voltage, over-current, phase-error protection 


Suitable for a wide range of stepping motors, from NEMA size 17 to 34. It can be used in various kinds of machines, such as laser cutters, laser markers, high precision X-Y tables, labeling machines, and so on. Its unique features make it an ideal solution for applications that require both low-speed smoothness and high speed performances.
