A16B-3200-0330 - CPU Board - FANUC
This FANUC CPU board is part number A16B-3200-0330. It is installed on FANUC RJ3 Robot.
This CPU card is at your disposal to replace your defective equipment and has a guarantee adapted to your needs.
Card reconditioned and tested on bench manufacturer (Test 100%).
The CNC control unit consists of the control unit rack, the power unit and printed circuit boards installed in the rack.
On top of the rack is a cooling fan motor. At the rear there is a back plane in which the printed circuit boards are pluged. As shown in the figure below, the upper cover of the control rack opens providing access to the fan motor for possible replacement.
The power unit is installed in the slot closest to the right edge of the rack. The PMC board is inserted into the second slot from the right rack edge. The main CPU board is inserted into the third slot from the right rack edge.
When sub CPU board (or editional axis board) is inserted, it is inserted into the fourth slot from the right rack edge. The remaining other slots are used for option boards. The sequence order of the option boards in the option slots makes no difference in the CNC operation. However, in order to avoid confusion, option boards are inserted according to kinds of the boards.
At the front of a printed circuit board, the interface connectors and LED display are installed and a plastic front panel is attached. There is also a connector attached at the rear edge of the printed circuit board for connecting to the F–BUS back plane.
The modules are small printed circuit boards with surface mount devices mounted on both sides. One edge of each module board has connector electrodes. Module boards are attached by inserting them in the module connectors on the printed circuit board, simplifying the replacement of the module boards. There are a number of modules types available and the circuit function for each is different. Therefore, the connector location for installing each module on the printed circuit board is fixed. If a module is not installed in the correct connector, the system may fail to operate correctly and the circuitry of the control unit or the module itself may be damaged.
However, some modules (ROM, SRAM, etc.) are interchangeable with respect to the signal assignment, enabling the insertion of the module to the connector of the interchangeable module.
FANUC is a Japanese manufacturer of industrial robots, machining centers and numerical controls for machine tools
Since its creation in 1956, when the company’s founder, Dr. Seiuemon Inaba, introduced the concept of digital controls, FANUC has always been at the forefront of manufacturing techniques in the world. Moving from the automation of a single machine in the late 1950s to the automation of entire production lines over the following decades.
