9.1
Inspection Interval
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 5. Conduct periodical inspections
according to the inspection interval in " Table 1 Inspection Items ".
In " Table 1 Inspection Items ", the inspection items are categorized by 3 types of operation:
operations which can be performed by personnel authorized by the user, operations which
can be performed by trained personnel, and operations which can be performed by service
company personnel. Only specified personnel are to do 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 ON THE POWER.)
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.
• Do not remove the motor, or release the brake.
Failure to observe this caution may result in injury from unexpected turning of the table.
• The inspection interval depends on the total servo operation time.
• For axes which are used very frequently other than arc welding, it is recommended that
inspections be conducted at shorter intervals. Contact your Yaskawa representative.
