7.3.2 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.
