1. Introduction, Features and Applications
Introduction
The DM860T 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, DM860T can drive a stepper motor at
much lower noise, lower heating, and smoother movement. Its unique features make DM860T 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 18-80VAC or 36-110VDC

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, size from NEMA24 to 34. 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.
