1. Introduction, Features and Applications
Introduction
The DM860 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.
Compared with traditional analog drives, DM860 can drive a stepper motor at much lower noise,
lower heating, and smoother movement. Its unique features make DM860 an ideal choice for high requirement
applications.
Features
l
Anti-Resonance provides optimal torque and nulls mid-range instability
l
Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother
motor movement
l
16 selectable microstep resolutions including 400, 800, 1600, 3200, 6400, 12800, 25600, 51200, 1000, 2000, 4000,
5000, 8000, 10000, 20000, 40000
l
Input voltage 24-80VDC
l
8 selectable peak current including 2.40A, 3.08A, 3.77A, 4.45A, 5.14A, 5.83A, 6.52A, 7.20A
l
Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input
l
Automatic idle-current reduction
l
Suitable for 2-phase and 4-phase motors
l
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.
