This manual details the installation, wiring, DIP switch settings, and operation of the KND BD3D-C dual-axis three-phase hybrid stepper motor driver.
The KND BD3D-C is a dual-axis three-phase hybrid stepper motor driver designed for use with KND1, 10, and 100 series CNC systems. It features AC servo control principles with full digital current loop control to ensure smooth low-speed operation without resonance or crawling. The device supports phase currents from 1.0A to 6.8A and offers multiple subdivision settings down to a minimum step angle of 0.03 degrees. This manual is written in Chinese.
