5. General Maintenance
M anipulator (S5 / PS series)
Inspection Point
Check for tram mark misalignment or damage at
the home position. (Visual)
Clean the area of motion range for each joint if
dust or spatter is present.
Check for damage and outside cracks. (Visual)
Tighten loose bolts. Replace if necessary.
(Use Spanner, Wrench)
Tighten loose screws. Replace if necessary
(Use Spanner, Wrench)
Check for loose connectors. (Manual)
Check for proper belt tension and wear.
(Manual)
Check for proper belt tension and wear.
(Manual)
Check for conduction between the main
connector of base and intermediate connector. *1
Check for wear of protective spring. *1
(Visual, Multimeter)
Replace the battery unit when an error warning
that low battery status is occurring at startup of
the software or every three years.
Keep the oil seals clean removing any dust such
as metal powders. (Visual)
Remove the condensation if it presents in
manipulator. *3
(Use Screw-driver, Wrench )
*1 When checking for conduction with a multimeter, connect the battery (for
backing up motor encoder) to the BAT and OBT connectors, which are encoder
connectors for maintenance, on the motor side. Then, disconnect the encoder
connector on the cable unit side from the motor. If you disconnect the encoder
connector on the cable unit side from the motor before connecting the battery to
the BAT and OBT connectors, the arm position data will be lost and the arm
will need to be calibrated again.
*2 Replace the cable unit every 24000 hours.
*3 When the manipulator is used in the environment where rapid changes in
temperature and humidity occur, perform the inspection more often than
specified above.
