Introduction

The DM556EU 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 20-48VDC and it can output up to 5.6A current. All the micro step and output current are done via DIP switches. Therefore, the DM556EU are ideal choices for applications requiring simple step & direction control of NEMA 23, 24 and 34 stepper motors.


Applications

The DM556EU stepper drive is 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.

Pinout and Description

Connector P1

Pin Function

Details

PUL﹢(+5V)

Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each rising or falling edge active (software configurable); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) , this input represents clockwise (CW) pulseactive both at high level and low level (software configurable). For reliable response, pulse width should be longer than 2.5μs. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and ENA signals.

PUL- (PUL)

DIR+ (+5V)

DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation; in double-pulse mode (software configurable), this signal is counter-clock (CCW) pulseactive both at high level and low level (software configurable). For reliable motion response, DIR signal should be ahead of PUL signal by 5μs at least. 4-5V when DIR-HIGH, 0-0.5V when DIR-LOW. Please note that rotation direction is also related to motor-Driver wiring match. Exchanging the connection of two wires for a coil to the Driver will reverse motion direction

DIR- (DIR)

ENA+ (+5V)

Enable signal: This signal is used for enabling/disabling the Driver. High level (NPN control signal, PNP and Differential control signals are on the contrary, namely Low level for enabling.) for enabling the Driver and low level for disabling the Driver. Usually left UNCONNECTED (ENABLED).

2 400 OFF ON ON ON
4 800 ON OFF ON ON
8 1600 OFF OFF ON ON
16 3200 ON ON OFF ON
32 6400 OFF ON OFF ON
64 12800 ON OFF OFF ON
128 25600 OFF OFF OFF ON
