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 that is suitable for Cnc drive . 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, Cnc drive, etc.

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, works well as Cnc drive as well
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 200KHz, 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-curren protection
