Leadshine Technology Co., Ltd. is one of the largest technology companies involved in the production of high-quality motion control products in the world. The company's DM556 digital stepper motor driver Leadshine is a professional driver developed with DSP advanced control algorithm. The algorithm provides a unique way of smooth movement, ensures optimal torque and eliminates mid-range instability. It is suitable for two-phase and four-phase stepper motor Nema 23, Nema 24 and Nema 34 with less than 5.6 A phase current. The drive voltage is from 20VDC to 50VDC.

Key Features:

  • Anti-resonance provides optimal torque and eliminates mid-range instability
  • Auto-identification and auto-configuration of parameters enables optimal settings for different engines.
  • 15 microstep resolutions: 400, 800, 1600, 3200, 6400, 12800, 25600, 1000, 2000, 4000, 5000, 8000, 10000, 20000, 25000
  • Soft start without stepper motors skipping when power is turned on
  • Input voltage 18-50 VDC (36 VDC recommended)
  • Maximum drive current 5.6 A
  • Automatic reduction of idle current
  • Suitable for 2-phase and 4-phase motor
  • Input pulse frequency up to 200 KHz, TTL compatible and optically isolated input
  • Supports PUL/DUR and CW/CCW modes of operation
  • Protection against overvoltage and overcurrent
