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 inter-
vals are classified into six levels. Conduct periodical inspections according to the inspection
schedule in "Table 7 Inspection Items".
In "Table 7 Inspection Items", the inspection items are categorized by three types of opera-
tions: operations which can be performed by personnel authorized of the user, operations
which can be performed by personnel being trained, and operations which can be performed
by service company personnel. Only specified personnel are to do the inspection work.
• The inspection interval must be based on the servo power supply ON time.
NOTE
• These inspections were developed for applications where the manipulator is used for arc
welding work. For any different or special applications, the inspection process should be
developed on an case-by-case basis.
For axes which are used very frequently (in handling applications, etc.), it is recom-
mended that inspections be conducted at shorter Intervals. Contact your Yaskawa repre-
sentative.
