DM556 Digital Low-Voltage Stepper Motor Drive, Using The Latest 32-bit DSP Technology.

Categories: ,

The DM556 is a versatile fully digital stepping driver based on a DSP with advanced control algorithm. The DM556 is the next generation of digital stepping motor controls. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instabilities. Motor self-test and parameter auto-setup technology offers optimum responses with different motors and makes it easy to use. The driven motors can run with much smaller noise, generate less heat, and move smoother than most other drivers on the market.

Its unique features make the DM556 an ideal solution for applications that require low-speed smoothness. Compared to the DM442, the DM556 provides a large voltage range and higher output current to able to drive a larger variety of stepper motors. Furthermore, the DSP of the DM556 is capable of driving the motors at higher speeds (above 3000 RPM) offering servo-like performance.



  1. Anti-Resonance, provides optimum torque and nulls mid-range instabilities
  2. Supply voltage up to +50 VDC (recommended not to exceed 45 V because of “back EMF”)
  3. Output current programmable, from 1.4 A to 5.6 A (DM556) and  1.0 A to 4.2 A (DM542)
  4. Automatic idle-current reduction (in standstill mode) to reduce motor heating; function switchable (reduction rate can be software configured)
  5. Motor self-test and parameter auto-setup technology, offers optimum responses with different motors
  6. Pulse input frequency up to 200 kHz
  7. TTL compatible and optically isolated input
  8. Microstep resolutions programmable, from full-step to 25000 steps/rev
  9. Suitable for 2-phase and 4-phase motors
  10. Over-voltage, over-current, phase-error protections



Suitable for a wide range of stepper motors of NEMA sizes 17, 23 und 34  (42 x 42 mm to 86 x 86 mm). 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 well suited for applications where low noise levels, less heat development, high speed and high precision are desired.

NOTE: NEVER disconnect or connect the motor while the power source is connected to driver and enegized!
