2ph 42mm NEMA17 57mm NEMA23 motor DSP Digital Stepper Drive DM442 18-40VDC 1.46-4.2A Leadshine New   The DM442 stepper drive adopts advanced features like electrical damping, anti-resonance, start-up smoothing, multi-stepping. With the input voltage of 20 - 40 VDC and output current of 1.46 - 4.20 A, it is capable of driving a wide range of 2-phase stepper motors with high precision at extra smoothness, quietness, and very low motor heating. A DM442 stepper drive is easy to setup and configure via DIP switches. There are 16 resolution settings from 200 - 25600, and 7 output current settings from 1.46 - 4.20. Also, a user can simply set the idle current to full (100%) or 50% of the output current via a DIP switch. Compared to the DM432C, DM442 can output more current. What’s more, owing to its higher performance DSP, driven motors can achieve much higher speed  than that of the DM432C, offering servo-like performances.   Features: Extra-low motor noise offers excellent quietness Anti-Resonance, provides optimum torque and nulls mid-range instability Self-test and Auto-configuration technology, offers optimum responses with different motors Microstep resolutions programmable, from full-step to 102,400 steps/rev  Supply voltage up to +40 VDC  Output current programmable, from 0.5A to 4.2A Pulse input frequency up to 200 KHz  Automatic idle-current reduction Supports PUL/DIR and CW/CCW modes   Specifications Model Phase Current(A) Voltage(V) Microstep resolution Adaptive motor Weight(kg) Dimensions(mm) DM422 2 0.5-2.2 18-36 DC 1-256 39 42 0.15 86*55*20 DM442 2 1.4-4.2 18-36 DC 1-256 42 57 0.2 116*69*26.5 DM542 2 1.0-4.2 18-48 DC 1-256 57 86 0.23 118*75.5*33 DM556 2 2.1-5.6 18-48 DC 1-256 57 86 0.28 118*75.5*33 DM856 2 2.1-5.6 18-70 DC 1-256 57 86 0.28 118*75.5*33 DM870 2 2.1-7.0 18-70 DC 1-256 57 86 0.28 118*75.5*33 DM860 2 2.4-7.2 18-80 DC 1-256 57 86 0.38 151*97*48 DM1182 2 2.2-8.2 90-130 AC 1-256 86 110 1.3 200*145*83 DM2282 2 2.2-8.2 180-240 AC 1-256 86 110 130 1.7 200*145*83 3DM580 3 2.5-8.0 18-48 DC 1-256 57 86 0.27 118*75.5*34 3DM2283 3 2.9-11.7 180-240 AC 1-256 86 110 130 1.7 200*145*83        Mechanical Specifications ( unit: mm [inch] )   Applications: For a variety of small and medium sized automation equipment and instruments, such as: laser processing equipment, engraving equipment, medical equipment, measuring equipment, electronic processing equipment, textile and garment equipment.
