Units and Circuit Boards in the CPU Unit
Control Circuit Board (JANCD-NCP01)
This board performs to control the entire system, display to the programming pendant, control
the operating keys, control operation, calculate motion type. This board has the Serial inter-
face for RS-232C, video output, PS2 connector, and LAN (100BASE-TX/10BASE-T). But this
board, however, cannot be used for video output and PS connector. (The video output and the
PS connector must be adjusted by the manufacturer only.)
Control Power Supply (CPS-420F)
This unit supplies the DC power (DC5V, DC24V, DC3.3V, DC±12V) for control (system, I/O,
brake). It is also equipped with the input function for turning the control power supply ON and
OFF.
