1. GENERAL ÎÎ ÎÎ B–62075E/03 Various racks for a control unit, power units, and printed circuit boards shown in the figure below can be used to configure a control units. Combination of these components depends on a machine tool for which the control unit is used. Fig. 1.1.1 (b) shows the configuration of the control unit of the Series 15–B.

B–62075E/03 1. GENERAL 1.1.2 Configuration of the printed circuit boards in the CNC control unit As shown in Fig. 1.1.2, a printed circuit board consists of a printed circuit board and a number of modules installed perpendicularly to the board. 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.
