Controller and Driver integrated This unit combines a stepper motor controller and driver functions in one module. It can drive the motor and also monitor and control the working state of the stepper motor in real time. 4 Control Modes Builtin parameter work mode plus flexible external control options. It can be controlled by external buttons, other drivers, or UART commands, providing versatile integration with your system. 9 Work States Builtin 9 default workflow programs to cover most applications and meet a variety of scenarios. Includes Forward, Reverse, Delay, Loop, Selflocking, Nolock, Rotating speed, and additional modes. Forward and Reverse Rotation direction can be changed by pressing a button or by adjusting a potentiometer. The direction can also be automatically changed through the selected working mode to support multiscene and multiapplication use. Use scenarios 3D printer or CNC axis control: precise positioning with realtime state monitoring, easy integration via external buttons, UART, or other drivers, and multiple workflow modes to suit different print or machining tasks. Automated motion platform or conveyor subsystem: leverage forward/reverse, delay, and loop modes to manage cycles, hold positions with selflocking, and control speed for synchronized operations. Robotics or laboratory automation: remote control through UART or external switches, automatic direction changes for multiscene experiments, and a compact, integrated solution for compact control loops.
