The DM870 is a versatility fully digital stepping driver based on a DSP with advanced control algorithm. The DM870
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 self-test and parameter auto-setup technology offers
optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise,
lower heating, smoother movement than most of the drivers in the markets. Its unique features make the DM556
an ideal solution for applications that require low-speed smoothness.

Compared to the DM432, broader input voltage and output current ranges make the DM870 can drive much more
motors than the DM432. What’s more, owing to its higher performance DSP, driven motors can achieve much
higher speed (above 3000RPM) than that of the DM432, offering servo-like performances.

Applications:
Suitable for a wide range of stepping motors, from NEMA frame size 17 to 34. It can be used in various kinds of
machines, such as laser cutters, laser markers, high precision X-Y tables, labeling machines, and so on. Its
unique features make the DM870 an ideal solution for applications that require both low-speed smoothness and
high speed performances.
