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:
