5.4 Internal Inspections
Turn OFF the power, remove the side cover and have a visual inspection.
When inspecting the interior, check the following items.
Main unit Loose mounting bolts, other loose items
Guide section Lubrication, buildup
Ball screw Lubrication, buildup
Visually inspect the interior of the equipment. Check whether dust or other foreign matter has gotten inside and
check the lubrication state.
The lubrication may have turned brown. This is not a problem as long as the travel surfaces shine as though they
are wet.
If the grease is mixed with dust and does not have a shiny appearance, or if the grease has lost its efficacy due to
prolonged use, then clean each section and reapply grease.
The procedure for internal inspections is outlined below.
1) With 2.5mm (RA5C, RA5R) or with 3mm (RA6C, RA6R) hex wrench, loosen the screws holding the frame
cover, and detach the frame cover.
2) Check inside.
Extend the rod when checking the ball screw. The ball screw will appear. Slide the rod manually with hand or
move it with JOG operation of the controller.
3) After finishing the inspection, assemble back in the reverse order.
