Chapter 5 Maintenance

x 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.

x The standard inspection interval is six months to one year. If the environment warrants, however, the

interval should be shortened.

1. Inspection points

x Check to see if the supply voltage to the controller is inside the specified range.

x Inspect the ventilation holes in the controller and remove dirt, dust and other foreign attachments, if

any.

x Inspect the controller cables (controller o actuator) and check for any loose screws or cable

disconnection.

x Check the controller mounting screws, etc., for looseness.

x 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

x Cables

x System-memory backup battery (optional): AB-5 by IAI -- Must be replaced after approx. 5 years*

x Absolute-data backup battery (optional): AB-5 by IAI -- Must be replaced after approx. 2 years*

(Absolute specification)

*: The actual replacement timing will vary depending on the use condition. For details, refer to “

Battery Backup Function” in Appendix.

When the battery voltage drops, an applicable error code will be displayed on the panel window.
