Features • Dual Operation Modes: Choose between jog and self-lock modes for versatile control, allowing for precise adjustments based on your project needs • Customizable Angle Settings: Easily set different CW and CCW angles, enabling tailored motion control for your specific applications • Automatic Homing Function: The device automatically returns to a starting position after a set distance, enhancing efficiency and simplifying operation • Infinite Cycle Process: Enjoy seamless operation with continuous rotation in both directions, providing reliable and repetitive performance • Robust and Durable Design: Built with a stable structure and high-quality components, ensuring long-lasting performance and reliability in various environments Features: 1、TWO MODES: Jog is turn on when a signal is given, stop when the signal disappears. Self lock is turn on when a signal is given, and stop when a signal is given again 2、SETTABLE ANGLE: Give CW signal, CW A distance stop; give CCW signal; CCW B distance stop, the CW and CCW angles can be set to different 3、AUTO HOMING: Automatically stop when the signal is turned A distance, after a delay of C time, it will automatically return, and will automatically stop when it is turned CW again for A distance, and the same is true for infinite loop CCW 4、CYCLE PROCESS: After power on, it will automatically rotate CW for a distance of A, stop for C seconds and then CCW for B distance and stop for C seconds, infinite loop 5、STABLE AND : Stepper motor controller come with stable structure, excellent performance and long service life Specification: Item Type: 42 57 Stepper Motor Controller Material: ABS Color: Black and blue Power Supply Range: DC 8V~24V universal Speed Range: 0.1~999 Minutes(with own power off memory function) Positive And Negative Pulse Range: 10~99990 Pulses Delay Adjustable Time Range: 0.1 Seconds to 999 seconds Function Selection Setting Range: P-1~P-6 Subdivision Selection Setting Range: 1~128 subdivisions Package List: 1 x 42 57 Stepper Motor Controller Package List 1 x 42 57 Stepper Motor Controller
