Introducing the Step Motor Controller, a precision module for single-axis stepper motors. It offers multiple pre-set operating modes for optimal motion path selection and retains settings for distance, speed, delay, and cycles even after power-off. Ideal for general industrial control applications, it can operate independently or with other systems, but is not suitable for critical safety applications. Features: Widely applicable in various industrial settings. Clear LCD display for easy monitoring. Supports both automatic and manual operation modes. TTL serial communication for remote control capabilities. Comprehensive system functions including automatic, manual, settings, and serial port control. Specifications: Protection against input reverse connection Remote Communication: TTL serial port Speed Range: 0.1 to 999 RPM Forward/Reverse Pulses: 1-9999 Cycle Work Times: 1-9999 Color: As Shown Material: ABS Package Contents: 1 stepper motor controller 1 connecting cable Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
