Introduction The DMA860H is a fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with traditional analog drives, DMA860H can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DMA860H an ideal choice for high requirement applications. Features

  • Anti-Resonance provides optimal torque and nulls mid-range instability
  • Motor auto-identification and parameter auto-configuration technology, offers optimal responses with different motors
  • Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement
  • 16 selectable microstep resolutions including 400, 800, 1600, 3200, 6400, 12800, 25600, 51200, 1000, 2000, 4000, 5000, 8000, 10000, 20000, 40000
  • Soft-start with no “jump” when powered on
  • Input voltage 36-112VDC or 24V—80VAC
  • 8 selectable peak current including 2.40A, 3.08A, 3.77A, 4.45A, 5.14A, 5.83A, 6.52A, 7.20A
  • Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input
  • Automatic idle-current reduction
  • Suitable for 2-phase and 4-phase motors
  • Support PUL/DIR and CW/CCW modes
  • Over-voltage, over-current protections

Applications Suitable for a wide range of stepping motors, from NEMA size 17 to 42. It can be used in various kinds of machines, such as X-Y tables, engraving machines, labeling machines, laser cutters, pick-place devices, and so on. Particularly adapt to the applications desired with low noise, low heating, high speed and high precision.
