Part 1 Installation
Chapter 7 Maintenance
• Routine maintenance and inspection are necessary so that the system will operate properly at all
time. 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.

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)
--- Battery life: Approx. 1 year *
• Absolute-date backup battery: AB-3 by IAI
--- Battery life: Approx. 3 years *
(Absolute-data backup battery is installed on the robot.)
• Fuses
* The actual battery life will vary depending on the use condition.
(Note 1) CR2032 is a standardized product and can be used with products by any manufacture.
Memory backup
The X-SEL Controller saves program, position, coordinate system and parameter data to its flash
memory (when written to the flash memory). The data saved by the system-memory backup battery
are positions, coordinate system data, SEL global data and error lists. (Refer to Chapter 1, “How to
Save Data,” of Part 3.)
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, A23 or D72
In the case of a low battery voltage of the absolute-data backup battery, the axis-driver status LED
will also illuminate.
