Wide range of applications, LCD display, automatic and manual multi-mode, TTL serial communication. Main functions of the system: automatic, manual, setting, serial port control. This is an operation control module designed for single-axis stepper motors. The module has 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 when powered off. It can operate independently or be integrated with other systems. Suitable for general industrial control applications. Not intended for use in special industries such as medical treatment, fire protection, or life-critical environments.
