The 2LD556 is a versatility fully digital stepping driver based on a DSP with advanced control algorithm. The 2LD556 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 auto-identification and parameter auto-configuration 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 2LD556 an ideal solution for applications that require low-speed smoothness.
2LD556 can drive motor to achieve much higher speed (above 3000RPM) than previous generation analog drivers, offering servo-like performances.
