9 Maintenance and Inspection
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 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.
DANGER
• 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, and do not release the brake.
Failure to observe these safety precautions may result in death or
serious injury from unexpected turning of the manipulator's arm.
WARNING
• Before maintenance or inspection, be sure to turn the main power
supply OFF, 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.
CAUTION
• The battery pack must be connected before removing detection
connector when maintenance and inspection.
Failure to observe this caution may result in the loss of home position
data.
NOTE
• The inspection interval depends on the total servo opera-
tion time.
• 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 appli-
cations, etc.), it is recommended that inspections be con-
ducted at shorter intervals. Contact your YASKAWA
representative.
• To maintain the sealing performance, small quantity of oil
used may leak from the bottom part of the gas balancer.
