Replacing the Robot I/F Circuit Board (JANCD-NIF01)
Replacement Procedure
1. Follow the replacement procedures 1 to 5 of " Replacing the Robot I/F Unit (JZNC-
NIF01) " to remove the robot I/F unit from the CPU rack.
2. Remove five screws fixing the I/O circuit board (JANCD-NIO01) and the robot I/F cir-
cuit board (JANCD-NIF01).
3. Disconnect the I/O circuit board and the robot I/F circuit board with due care.
4. Remove five studs fixing the robot I/F circuit board (JANCD-NIF01) on the base plate.
5. Fix new robot I/F circuit board (JANCD-NIF01) with five studs on the base plate.
6. Connect the I/O circuit board (JANCD-NIO01) to the new robot I/F circuit board
(JANCD-NIF01) with the onboard connector.
7. Tighten five screws to fix the I/O circuit board (JANCD-NIO01) and the robot I/F cir-
cuit board (JANCD-NIF01).
8. Insert the robot I/F unit into the slot of the CPU rack.
9. Tighten upper and lower screws of the robot I/F unit.
10. Connect all cables disconnected in the procedure 1.
11. Set the rotary switch as the same value as the removed board.
12. Start the system in maintenance mode and load the backup data.
1) Turn ON the power with pressing the [MAIN MENU] key.
2) Change the security to management mode and select {TOOL}
⇒ {Compact-
Flash}
⇒ "CMOS LOAD"
• Turn OFF the power before replacing the robot I/F circuit board (JANCD-NIF01).
• Be sure to back up robot data before replacing the robot I/F unit since the robot I/F unit
contains important data such as robot jobs and parameters.
• There are some versions which require maker mode operations after replacing the robot
I/F circuit board.
Contact your Yaskawa representative for maker mode operations.
• Before removing the robot I/F unit from the CPU rack temporarily, turn ON the system
power and charge the onboard capacitor for one hour. The CMOS data on the robot I/F
unit are kept temporarily by the onboard capacitor power. The capacitor is fully charged in
one hour, and discharged in 16 hours when the I/F unit is removed from the CPU rack.
If the capacitor is discharged, the CMOS data will be cleared and all the system settings
and user settings will be lost.
Refer to the procedure 10 of " Replacing the Robot I/F Unit (JZNC-NIF01) " to recover
data.
• For under the versions: NS3.10-00, NS2.30-02, NT2.40-02, NS2.0P-00,
NS2.0P-12, and NJ3.20-00, initialize the system in maker mode before load-
ing the CMOS data.
• For under NS1.8HA-00 versions, start the system in online mode after load-
ing the CMOS data, and load all the individual data EXCEPT jobs and
parameters.
