Comparison DM556/ DM556EU/ EM556S
Product Description:

The DM556EU is a digital stepper drive with simple design and easy setup. By implementing Leadshine’s 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 - 50 VDC and it can output up to 4.2 A current.

All the micro step and output current are done via DIP switches. Therefore, the DM542EU is an ideal choice for applications requiring simple step & direction control of NEMA 23, 24, and 34 stepper motors.

Features:
  • Anti-Resonance for optimal torque, extra smooth motion, low motor heating and noise
  • Motor auto-identification and parameter auto-configuration for optimal torque for a wide range of motors
  • Step & direction (PUL/ DIR) control
  • Multi-Stepping for smooth motor movement
  • Optically isolated inputs
  • Input voltage 20 – 50 V DC
  • 16 selectable micro-step resolutions of 400 - 25,600 via DIP switches
  • 8 selectable output current settings of 1.8 - 5.6 A via DIP switches
  • Smooth motor start-up without “jump”
  • Pulse input frequency up to 200 kHz
  • Automatic idle-current reduction
  • Protections for over-voltage and over-current
