Fanuc Robot M-710i

Warning: This maintenance check requires trained personnel with PPE!

Mechanical unit cable in good condition?

If cable is not in good condition, replace it.

Contact information of local FANUC representative

Controller batteries in good condition?

If batteries are not in good condition, replace them.

Sign off on the robot maintenance

Check whether the cable connected to the teach pendant, operation box and robot are unevenly twisted or damaged

Retighten the end effector mounting bolts

Retighten the cover mounting bolts, the robot installation bolts, bolts to be removed for inspection, and bolts exposed to the outside

Refer to the recommended bolt tightening torque guidelines at the end of the manual

An adhesive to prevent bolts from loosening is applied to some bolts. If the bolts are tightened with greater than the recommended torque, the adhesive might be removed. Therefore, follow the recommended bolt tightening torque guidelines when retightening the bolts

Check the mechanical stopper and the adjustable mechanical stopper

Clean spatters, sawdust and dust

Check that spatters, sawdust, or dust does not exist on the robot main body. If dust has accumulated,remove it. Especially, clean the robot movable parts well (each joint and the wrist flange)

The insulation failure occurs when the spatter has collected around the wrist flange or welding torch, and there is a possibility of damaging the robot mechanism by the welding current. (See Appendix C)

Inspection points of the mechanical unit cables

For the J1-axis, inspect the cables from above the J2 base and from the side by removing the metal plate on the side of the J1 base. When the J2 base cover is attached, inspect there after removing the cover. For the J2-axis, inspect there after removing the J2 base side cover. For the J3-axis, check cables after remove cover of J3 casing. When severe dust/liquid protection option is selected, gasket is attached to the cover. If you remove covers, be sure to exchange gasket for the new article.

Check the cables for a jacket break and wear. If wires of the cable appear, replace it.

Inspection points of the connectors

- Power/brake connectors of the motor exposed externally

- Robot connection cables, earth terminal and user cables

- Circular connector: Check the connector for tightness by turning it by hand.

Check for external damage or peeling paint

Check the mechanical cable. damaged or twisted

Check the motor connector and exposed connector loosening

Tighten the cover and main bolt

Check the mechanical stopper and adjustable mechanical stopper

Check the end effector (hand) cable

Check for damages to the teach pendant cable, the operation box connection cable or the robot connection cable

Check whether the cable connected to the teach pendant, operation box and robot are unevenly twisted or damaged. If damage is found, replace the damaged cables.

Check for damage to the mechanical unit cable (movable part)

Check the connection of each axis motor and other exposed connectors

Retightening the end effector mounting bolts

Retightening the cover mounting bolts and external main bolts

Retighten the cover mounting bolts, the robot

installation bolts, bolts to be removed for inspection, and bolts exposed to the outside. Refer to the recommended bolt tightening torque guidelines at the end of the manual.

An adhesive to prevent bolts from loosening is applied to some bolts. If the bolts are tightened with greater than the recommended torque, the adhesive might be removed. Therefore, follow the recommended bolt tightening torque guidelines when retightening the bolts.
