Leadshine ND556 2-phase Hybrid Stepper Drive
The ND556 is a high performance microstepping drive using pure-sinusoidal current control technology. It is particularly suitable for the applications desired with extremely low noise and low heating, compared with microstepping drives 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 therefore the ND556 can make stepper motors offer servo-like performances. Compared to the MD556, it offers higher performance-price ratio.
