1. Introductions
The DM556T is a digital stepper drive with simple design and easy setup. By implementing STEPPERONLINE 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.
