Forward and Reverse control Bidirectional motion control can be achieved by pressing a button or turning a potentiometer. The device can automatically switch direction through its working mode to support multiple scenes and applications. Controller and Driver Integrated step motor controller and driver functions in one unit. Allows not only driving the motor but also realtime control of the stepper motor state. 9 builtin work states Comes with 9 default workflow programs to cover common applications. Supports Forward, Reverse, Delay, Loop, Selflocking, Nolock, rotating speed control, and related modes for versatile use. 4 control modes In addition to the builtin parameter work mode, it can be controlled by external buttons. Compatible with other drivers or UART command control for flexible integration. Use scenarios Precision indexing and positioning in small automation tasks such as camera sliders, micropositioning stages, or compact CNC projects that require bidirectional motion and speed control. Applications needing holding or delaying actions, such as clamps, gates, or latching mechanisms, with options for selflocking or nolock modes. Prototype development and system integration where control is required from external controllers, other drivers, or UART commands. Key attributes Function: bidirectional control, automatic direction changes, realtime motor state management, and multiple builtin modes. Compatibility: supports external button input, other drivers, and UART command control for flexible integration. Performance: integrated controller and driver for reliable drive and responsive control in real time. Operation modes: builtin parameter work mode plus four external control options for versatile use.
