1. Introductions

The DM542E 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 20-50VDC and it can output up to 4.2A current.
All the micro step and output current are done via DIP switches. Therefore, the DM542E are ideal choices for
applications requiring simple step & direction control of NEMA 17, 23, and 24 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 1.0 – 4.2A 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 DM542E stepper drive are designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA 17, 23, and 24 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.
