Chapter 9 Maintenance
Routine maintenance and inspection are necessary so that the system will operate properly at all times. Be
sure to turn off the power before performing maintenance or inspection.
The standard inspection interval is six months to one year. If the environment warrants, however, the interval
should be shortened.
1. Inspection Points
Check to see if the supply voltage to the controller is inside the specified range.
Inspect the ventilation holes in the controller and remove dirt, dust and other foreign attachments, if any.
Inspect the controller cables (controller
actuator) and check for any loose screws or cable
disconnection.
Check the controller mounting screws, etc., for looseness.
Inspect each cable (axis link cable, general-purpose I/O cable, system I/O cable, power cable) for loose
connection, disconnection, play, etc.
2. Spare Consumable Parts
Without spare parts, a failed controller cannot be repaired even when the problem is identified quickly. We
recommend that you keep the following consumable parts as spares:
Consumable parts
Cables
System-memory backup battery: CR2032 (Note 1) --- Must be replaced after approx. 1.5 years* (Note 2)
Absolute-data backup battery: AB-5 by IAI --- Must be replaced after approx. 2 years* (Note 2)
(Absolute specification)
Fuses
(Note 1) CR2032 is a standardized product and can be used with products by any manufacture.
(Note 2) The actual replacement timing will vary depending on the use condition. For details, refer to “
Battery Backup Function” in Appendix.
Memory backup
The XSEL Controller saves program, position and parameter data to its flash memory (when written to the flash
memory). The data saved by the battery includes position data, SEL global data, error list and content of the
user-data backup memory in the controller with expanded memory (with gateway function).
(Refer to Chapter 1, “How to Save Data,” of Part 3.)
Caution
In the case of a controller with expanded memory (with gateway function), only positions from Nos. 1 to 10000
can be saved in the system memory.
To save position data from Nos. 10001 to 20000, the data must be written to the flash ROM.
When the battery voltage drops, an applicable error code will be displayed on the panel window.
Error Codes Indicating Low Battery Voltage
System-memory backup battery A01 or A02
Absolute-data backup battery A03 or A23
In the case of a low battery voltage of the absolute-data backup battery, the axis-driver status LED will also
illuminate.
