The DM860I 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, DM860I can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM860I an ideal choice for high requirement applications.

Key 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 20-80VDC
  • 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
