Description
Application Scenarios
In an automotive assembly line, the ABB RCX240 is deployed to control a gantry-style Cartesian robot responsible for windshield adhesive application. The controller executes precise 3D linear and circular interpolation paths, ensuring consistent bead geometry. Its multi-tasking function allows it to simultaneously manage the robot motion and a peripheral conveyor encoder tracking signal, while the “Push Function” provides torque-controlled press-fit verification of the windshield into the frame, all without requiring a separate PLC.

Technical Principles and Innovative Values
The ABB RCX240 integrates advanced motion control logic into a user-friendly platform, offering several key innovations for its class.
- Innovation Point 1: Mixed Robot Fleet Management: Unlike many controllers limited to one robot type, the RCX240 can control a hybrid system comprising a mix of SCARA, Cartesian, and single-axis linear motor robots (e.g., FLIP-X and PHASER series) from a single unit, simplifying system integration and reducing hardware costs.
- Innovation Point 2: Advanced Path Planning & Push Control: The controller features sophisticated 2D and 3D linear/circular interpolation for smooth, high-speed motion. Its unique “Push Function” allows for torque-limited press-fit and insertion tasks, providing a cost-effective alternative to full-force feedback systems for assembly applications.
- Innovation Point 3: Dual-Synchronous Drive & Area Control: For handling heavy payloads or long strokes, the RCX240 supports dual-synchronous drive (controlling two motors on one axis). Combined with its “Area Check Output” function (triggering I/O when the robot enters a predefined zone), it enables complex, coordinated material handling scenarios.
