DMA860E Digital Stepper Drive User Manual
Page | 1
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 configurations can be easily done via built in DIP switches. Its
control type (step & direction or CW/CCW) and command smooth filtering can also be configured 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
Step & direction (PUL/DIR) or CW/CCW (double pulse) control
Input voltage 18-80VAC or 24-110VDC (recommended 20-70VAC or 30-90VDC)
200 KHz max pulse input frequency
16 microstep resolutions of 400-51,200 via DIP switches, or 200-51,200 via software (increase by 200)
8 output current settings of 2.4-7.2A via DIP Switches, or 1.0-7.2A via software (increase by 0.1)
Configurable control command smoothing for reducing motor vibration
Idle current reduction to 50% or 90% selection via SW4
Auto-tuning to match wide-range NEMA 23, 24, 34 and 42 stepper motors
Anti-Resonance for optimal torque, extra smooth motion, low motor heating and noise
Soft-start with no “jump” when powered on
Optically isolated inputs with 5V or 24V
Fault and Brake outputs
Over-voltage and over-current protections
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.
