Usage Tips: Wide range of applications LCD display Automatic and manual multi-mode operation TTL serial communication Main system functions: automatic, manual, setting, and serial port control This is an operation control module specifically designed for single-axis stepper motors. The module features built-in multiple fixed operation modes, allowing users to quickly select the appropriate motion trajectory. Distance, speed, delay, and cycle times can be saved and set even when powered off. It can operate independently as a standalone module or be integrated with other systems. Suitable for general industrial control applications; not intended for use in medical, fire safety, or life-critical environments.
