8.3.1
Unit and circuit board in the CPU unit
8.3.1.1
CPU board
The entire system is controlled with this circuit board. It controls the display on the
programming pendant, the control keys and the movements, and it calculates the
interpolation. This control circuit board has the serial interface for RS-232C/RS-422 and a
LAN connection (100Base-TX/10Base-T), USB (USB2.0).
8.3.1.2
Robot I/O circuit board
The robot I/F circuit board controls the entire robot system. It is connected to the control
circuit board (JANCD-YCP01-E) with a PCI bus interface on the rear. Connection to the
basic axis control circuit board (SRDA-EAXA21A) for high speed transmission.
NOTICE
Please do not change the factory setting of S1 (Factory setting is [0]).
8.3.1.3
CPU board (machine safety)
This circuit board (JANCD-YSF21-E) performs I/O processing or diagnosis processing for
the safety sequence, and it is connected with the CPU circuit board (JANCD-YCP21-E) by
the PCI Express bus I/F in the back circuit board.
It is also connected with the machine safety I/O logic circuit board by the high speed serial
communications (two lines).
8.4
CPS
This unit (JZNC-YPS21-E) supplies the DC power (DC5V, DC24V) for control (system, I/O,
brake). It is also equipped with the input function for turning the control power supply ON
and OFF.
