9 Maintenance and Inspection
9.1 Inspection Schedule
9.1
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 six levels as shown in
periodical inspections according to the inspection schedule in
In Table 9-1, the inspection items are categorized by three types of operations: operations to
be performed by personnel authorized by the user, operations to be performed by personnel
being trained, and operations to be performed by service company personnel. Only the
specified personnel are to do 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
handling application. If the manipulator is used for other application or if it is 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 even in case of the handling application. For details, contact your Yaskawa
representative.
