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 "Table 7 Inspection Items". Conduct
periodical inspections according to the inspection schedule in this table.
In Table 7, 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 trained
personnel; and operations to be performed by service company personnel. Only specified
personnel are allowed to perform the inspection work.
• Before maintenance or inspection, be sure to turn OFF the main power
supply, and put up a warning sign. (ex. DO NOT TURN THE POWER ON.)
Failure to observe this warning may result in electric shock or injury.
• Maintenance and inspection must be performed by specified personnel.
Failure to observe this caution may result in electric shock or injury.
• For disassembly or repair, contact your Yaskawa representative.
• When performing maintenance and inspection, make sure to connect
the battery pack before removing the encoder connector.
Failure to observe this caution may result in the loss of home position data.
• The inspection interval depends on the total servo operation time.
• The inspection intervals in Table 7 have been calculated based on the condition where
the manipulator is used for the arc welding application. For any different or special appli-
cations, the inspection intervals shall be calculated on an case-by-case basis. If the
manipulator will be used very frequently (for handling applications, etc.), inspections may
be required at shorter intervals. Contact your Yaskawa representative.
