Inspection Schedule
Proper inspections are essential not only to assure that the mechanism
will be able to function for a long period, but also to prevent malfunctions
and assure safe operation. Inspection intervals are classified into several
levels as shown in Table 9-1 "Inspection Items".
In Table 9-1, the inspection items are categorized by three types of
operations: operations which can be performed by personnel authorized
by the user, operations to be performed by trained personnel, and
operations to be performed by service company personnel. Only specified
personnel shall perform the inspection work.
• The inspection interval depends on the total servo
operation time.
• The following inspection schedule is based on the case
where the manipulator is used for arc welding application.
If the manipulator is used for other application or if it is
NOTE
used under special conditions, a case-by-case
examination is required.
The inspection may be conducted at shorter intervals if the
manipulator is used very frequently for the application
such as handling; in this case, contact your YASKAWA
representative.
