1. Introductions
The DM556T 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 20-50VDC and it can output up to 5.6A current. All the micro step
and output current are done via DIP switches. Therefore, the DM556T are ideal choices for applications requiring
simple step & direction control of NEMA 23, 24 and 34 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

TTL compatible and optically isolated inputs

Input voltage 20-50VDC

16 selectable micro-step resolutions of 400-25,600 via DIP switches

8 selectable output current settings of 1.8 – 5.6A 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 DM556T stepper drive are designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA 23, 24, and 34 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.
