FANUC RJ3iB Controller

The FANUC RJ3iB uses advanced technology packaged in a proven, reliable and efficient controller design. Process capability and open architecture features provide intelligence to improve application and motion performance while simplifying system integration. The R-J3iB Controller incorporates the plug-in options concept, which allows flexibility for application specific configurations while maintaining a commonality for all users of the system.

Additionally, the R-J3iB supports both analog and digital input and output modules while also allowing the addition of optional process I/O boards, as necessary.

The controller cabinet has an operator panel that provides easy, intuitive buttons with flashing LEDs to indicate operating and cycle conditions. This helps simplify daily operations, such as for simple powering up, running a program, and powering down.

Connected to the controller cabinet via a cable (internally connecting to the controllers Main CPU board), the teach pendant enables the performance of operations away from the controller. The teach pendant can teach program data, test and debug programs, and adjust variables with its 16-line by 40-character LCD display, menu-driven function keys, keypad keys, and status LEDs. Additionally, this pendant can monitor and control I/O to control EOATs and displaying current information on the status or position of the robot.
