This driver is brand Leadshine (The most famous stepper driver company in China), and STEPPERONLINE is the biggest distributor of Leadshine in China.

The Leadshine ND556 is a high performance microstepping driver using pure-sinusoidal current control technology. It is particularly suitable for the applications desired with extremely low noise and low heating, compared with microstepping drivers which apply pseudo-sinusoidal current control technology. Because pseudo-sinusoidal current control technology may make the output current to be a distorted sine wave or generates larger current ripple, and both of them may cause the motor working in a higher noise, bigger vibration and higher temperature condition. If the motor works in that condition for a long time, that may decrease motor torque, accelerate motor aging and short motor’s operating life. However the pseudo-sine precise current control technology applied by the ND556 can solve above problems very well and make it can offer servo-like performances. Compared to the MD556, it offers higher performance-price ratio
