The DM856 is a versatile fully digital stepping driver based on a DSP with an advanced control algorithm. The DM856 is the next generation of digital stepping motor controls. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. Motor auto-identification and parameter auto-configuration technology offer optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise, lower heating, and smoother movement than most of the drivers in the markets. Its unique features make the DM856 an ideal solution for applications that require low-speed smoothness. Compared to the DM432C, broader input voltage and output current ranges make the DM856 can drive much more motors than the DM432C. What’s more, owing to its higher performance DSP, driven motors can achieve much higher speed (above 3000RPM) than that of the DM432C, offering servo-like performances. It can be regarded as an improved model originating from DM556 while supporting a broader input voltage range.
