DM860 Driver

The DM860 stepper drive adopts advanced features like electrical damping, anti-resonance, start-up smoothing, multi-stepping... With the input voltage of 20 - 80 VDC and output current of 0.50 - 5.60 A, it is capable of driving a wide range of 2-phase stepper motors with high precision at extra smoothness, quietness, and very low motor heating.

Its multi-Stepping feature allows a low resolution step input to produce a much higher microstep output for smoother & quiet motor movement, and much lower motor heating. This feature will significantly improve the performance of your stepper control systems.
