Description 1. The new 32-bit DSP technology is adopted, and the most control algorithm is applied to greatly reduce the noise and vibration during motor operation, with low noise, low vibration and low temperature rise.2. DSP digital stepping motor driver, standard single pulse interface. Provide energy-saving semi-automatic current locking function, with automatic semi-current, overvoltage, undervoltage and overcurrent protection functions.3.1.4-5.6a eight gear current value is optional. The voltage of dm556 is DC 24v-50v, which is suitable for all two-phase hybrid stepping motors with current less than 5.6A. The semi enclosed casing can adapt to more severe environment. There are 16 kinds of Mini steps, and the output current has 8 gears.4. In the application field, 3D printers, engraving machines, marking machines, cutting machines, Phototypesetting, plotters, automatic packaging machines, dispensing machines, CNC machine tools and other automatic equipment have been significantly improved for users with large vibration and noise5. Dm556 is a new generation of high-performance digital stepping driver based on DSP, with advanced control algorithm. The motor driven by dm556 has less noise and vibration than other drivers on the market.Colour:As shownMaterial: PCB+ABSPackage Contents:1 x stepper motor driverOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
