The DMA860E is a digital stepper drive with simple design and easy setup. By implementing Leadshine advanced stepper control technology, this stepper drive is able to power 2-phase and 4 phase stepper motors smoothly with optimal torque and low motor heating & noise. Its operating voltage is 18-80VAC or 24-110VDC and it can output up to 7.2A current. All the micro step and output current are done via DIP switches. Therefore, the DMA860E are ideal choices for applications requiring simple step & direction control of NEMA 23, 24, 34 and 42 stepper motors.


  • Anti-Resonance for optimal torque, smooth motion, low motor heating and noise
  • Motor auto-identification and parameter auto-configuration for optimal torque from wide-range motors
  • Step & direction (PUL/DIR) and CW/CCW (via internal jumper set) control. Step & direction by default
  • Multi-Stepping for smooth motor movement
  • Optically isolated inputs
  • Input voltage 18-80VAC or 24-110VDC
  • 16 selectable micro-step resolutions of 400-51,200 via DIP switches
  • 8 selectable output current settings of 2.4 – 7.2A (RMS 1.5-6.0 A) via DIP switches
  • Soft-start with no “jump” when powered on
  • Pulse input frequency up to 200 KHz
  • Automatic idle-current reduction
  • Protections for over-voltage and over-current


The drive is suitable for a wide range of stepping motors, from NEMA frame size 23 to 42. It can be used in various kinds of machines including CNC machines, laser cutters, laser markers, high precision X-Y tables and labeling machines. Its unique features make the DMA860E an ideal solution for applications that require both low-speed smoothness and high speed performance.
