1. Introductions

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.

1.1 Features

 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
 Opto Isolation for input control signals
 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 via DIP switches
 Soft-start with no "jump" when powered on
 Pulse input frequency up to 200 KHz. TTL compatible and optically isolated inputs
 Automatic idle-current reduction
 Protections for over-voltage and over-current

1.2 Applications

The DMA860E stepper drive are designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA 23, 24, 34, and 42 hybrid
stepper motors. It can be easily adopted in many industries (CNC, medical, automation, packaging...), such as X-Y
tables, engraving machines, labeling machines, mills, plasma, laser cutters, pick and place devices, and so on. Its
excellent performance, simple design, and easy setup make it ideal for many step & direction control type applications.
