How It Works

The RWD-MM500 operates through a high-resolution stepper motor system that provides four-axis drive control (X, Y, Z, and diagonal movement) with maximum travel distance of 25mm in each direction. The system utilizes precision mechanical components to achieve positioning resolution down to 33 nm in fine range mode, while maintaining long-term stability of <10 nm/h at 24°C through thermal compensation and mechanical design.

Control is achieved through a rotary photoelectric encoder that can manage up to two manipulators simultaneously, allowing researchers to switch between manipulator arms during complex experimental procedures. The touch screen interface displays real-time position data in both relative and absolute coordinate systems, enabling precise navigation to predetermined locations and storage of working positions for experimental protocols requiring repeated positioning.

The system operates in either continuous increment mode for smooth movement or step increment mode for precise positional adjustments, with maximum movement speeds up to 2.9mm/s for efficient positioning between experimental locations.
