DMA882S Digital Stepper Drive User Manual
Page | 1
1. Introductions
The DMA882S 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 8.2A current. All the micro step and output current are done via DIP switches. Therefore, the DMA882S are ideal
choices for applications requiring simple step & direction control of NEMA 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
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 2.1 – 8.2A (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
1.2 Applications
The DMA882S 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.
