5.1.1.4 Replacing the Robot I/F Circuit Board (JZNCD-YIF01- E)
5 Replacing Parts
5.1 Replacing DX100 Parts
• Turn OFF the power before replacing the robot I/F circuit
board.
• Be sure to back up robot data before replacing the
circuit board since the robot I/F circuit board 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 circuit board (JANCD-
NOTE
YIF01- E) 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 circuit board are kept
temporarily by the onboard capacitor power in the YIF
board.
The capacitor is fully charged in one hour, and
discharged in 16 hours when the I/F circuit board is
removed from the CPU unit.
If the capacitor is discharged, the CMOS data will be
cleared and all the system settings and user settings will
be lost.
Replacement Procedure
1. Back up the robot data.
Insert a CF card for backup to the programming pendant, and start the
system in maintenance mode.
Select {FD/PC CARD} ⇒ {SAVE} ⇒ "CMOS SAVE" to save the CMOS
data.
Backup all the individual data for safe.
2. Turn OFF the power after making backup.
3. Disconnect all cables on the robot I/F circuit board.
4. Remove two screws fixing the robot I/F circuit board and rack.
5. Pull out the robot I/F circuit board from the rack.
6. Insert new robot I/F circuit board into the slot of the rack.
7. Tighten upper and lower screws of the robot I/F circuit board.
8. Connect all the cables disconnected in the procedure 3.
9. Set the rotary switch as the same value as the original I/F circuit board.
10. Start the system in maintenance mode and load the backup data.
Turn ON the power with pressing the [MAIN MENU] key.
Change the security to management mode and select {FD/PC CARD} ⇒
{SAVE} ⇒ "CMOS LOAD
