1. Introductions
The DM320T is a digital stepper drive with simple design and easy setup. By implementing 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 18-30VDC and it can output up to 2.2A current. All the micro step
and output current are done via DIP switches. Therefore, the DM320T are ideal choices for applications requiring
simple step & direction control of NEMA8,11, 14, 16, 17 stepper motors.
1.1 Features
Anti-Resonance for optimal torque, extra 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) control
Multi-Stepping for smooth motor movement
Optically isolated inputs
Input voltage 18-30VDC
8 selectable micro-step resolutions of 400-12800 via DIP switches
8 selectable output current settings of 0.3 – 2.2A via DIP switches
Soft-start with no “jump” when powered on
Pulse input frequency up to 60 KHz.
Automatic idle-current reduction
Protections for over-voltage and over-current
1.2 Applications
The DM320T stepper drive are designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA11, 14, 16, 17 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.
