The ND556 is a high performance micro-stepping driver using pure-sinusoidal wave current control technology. Current and micro-step settings are selected by DIP switches. Pure-sinusoidal drive technology offers smoother motion than a standard micro-stepping driver. This results in less resonance, higher achievable speed, lower motor heating, and longer machine life. To further lower motor heating and save energy, the driver will optionally reduce the motor current to 60% when the motor has been sitting stationary for half a second.


  • Micro-stepping, current chopping drive
  • Pure-sinusoidal precise current control technology
  • Extreme low motor noise
  • Both driver and motor low heating
  • High performance, low cost
  • The current semi-reduction automatically switches in on absence of clock pulses
  • Suitable for 4, 6 and 8 lead motors
  • Optically isolated input signals
  • DIP switch current setting with 8 different values
  • Over-voltage and short-circuit protection

The ND556 is suitable for a wide range of NEMA 17 and 23 stepping motors and suits various kinds of machines, including as X-Y tables, labeling machines, laser cutters, engraving machines, and pick-place devices.
