INTELLIGENT ACTUATOR
Part 1 Installation
Chapter 8 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.
(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) --- 1 year (Note 2)
 Absolute-data backup battery by IAI IA-XAB-BT --- 1 year (Note 2)

 Fuses
(Note 1) CR2032 refers to a battery conforming to the CR2032 standard, and any CR2032 battery
by any manufacturer can be used.
(Note 2) The actual battery life will vary depending on the use condition.
Memory backup
The X-SEL Controller saves program, position and parameter data to its flash memory (when written to
the flash memory). The data saved by the battery are positions, 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 or A23
In the case of a low battery voltage of the absolute-data backup battery, the axis-driver status LED will
also illuminate.
