Below is a how to video and a written procedure that covers backing up the CMOS.BIN file on a DX100.

DX100 CMOS Saving and Loading Procedure

The DX100 robot controller by Yaskawa Motoman utilizes a CMOS (Complementary metal–oxide–semiconductor) type memory for saving all system data. This memory is backed up by controller power when the unit is on; and by battery backup power when controller power is off. One of the issues with this type of memory is a power loss coupled with a low battery condition. At this point, corruption and loss of data may occur. The best preventive measure in the case of data loss or corruption is a complete CMOS backup performed when the system is received; and at regular intervals thereafter: most importantly after a configuration change.

The CMOS backup offers the end user a bit-by-bit rebuild of the entire data table of the DX100 controller. If the controller has data loss or corruption, the controller will boot into a Maintenance mode and will not be resettable without either a CMOS backup to load or a Yaskawa factory trained technician to reset the system. This may be an extremely expensive labor cost if the system configuration must be rebuilt from the beginning.

This procedure outlines the procedure for saving the complete CMOS in the DX100 controller.

1) Boot the controller into Maintenance mode by holding down the MAIN MENU key while
turning power on to the system. The key may be released after an audible “beep” is heard

2) After booting into Maintenance mode, go to Management level security using the
following selections using the SELECT key: SYSTEM > SECURITY > MANAGEMENT

3) After selecting MANAGEMENT mode, you will be prompted to enter a password. Enter
the password and press the ENTER key (Default password is 99999999) Now the
system will be in MANAGEMENT mode as can be verified by the three keys at the icon
on top right of screen

4) Now select the target external memory device to save the CMOS file. Select EXTERNAL
MEMORY > DEVICE > then select either CF: Pendant or USB: Pendant

5) Save the CMOS file. Select EXTERNAL MEMORY > SAVE > CMOS > Select Yes when
prompted

6) After selecting Yes, the CMOS file will begin saving. This will take up to several minutes
as the file is >19MB. During this time the controller will show that it is saving the CMOS
file. When it is complete, you will hear an audible “beep” and the bottom message line
will read “Maintenance Mode”

7) If you need to load a CMOS file back into your controller, follow the same steps as
above however select LOAD instead of SAVE on step 5. *Caution: ALL data previously
saved in the controller will be lost if a CMOS file is loaded! Only load a CMOS if
instructed by Yaskawa personnel or if the system configuration must be reverted back
to a previous state.
