5Maintenance and Inspection 5 Maintenance and Inspection The maintenance and inspection procedures to be carried out to use the robot for a long time without trouble are described in this chapter. The types and replacement methods of consumable parts are also explained. 5.1 Maintenance and inspection interval Maintenance and inspection are divided into the inspections carried out daily, and the periodic inspections carry out at set intervals.
5Maintenance and Inspection 5.2 Inspection items The inspection items for the robot arm are shown below. Also refer to section "5. Maintenance and inspection" in the "Controller setup, basic operation, and maintenance" manual, and inspect the controller. 5.2.1 Daily inspection items Carry out the daily inspections with the procedures given in Table 5-1.
Check and eliminate the cause. damage and adherence of foreign matter. If the cables are severely damaged, contact the Mitsubishi Service Department. 3-month inspection items Is the timing belt tension abnormal? If the timing belt is loose or too tense, adjust it.
The procedures for carrying out the periodic maintenance and inspection are described in this section. Thoroughly read the contents, and follow the instructions. This work can be commissioned to the Mitsubishi Service Depart- ment for a fee. (Never disassemble, etc., the parts not described in this manual.) The maintenance parts, etc., required for the user to carry out maintenance and inspection are described in...

5Maintenance and Inspection 5.3.3 Inspection, maintenance and replacement of timing belt This robot uses a timing belt for the drive conveyance system of the J5 axis. Compared to gears and chains, the timing belt does not require lubrication and has a low noise. However, if the belt usage method and tension adjust- ment are inadequate, the life could drop and noise could be generated.

5Maintenance and Inspection (3) Timing belt tension Fig.5-7 : Belt tension The timing belt can satisfactorily convey the drive and keep a durable force only when it has an adequate tension. The belt tension should not be too tight or too lose. Instead, it should be adjusted to a degree that elasticity is felt when the belt is pressed with the thumb.
5Maintenance and Inspection 5.3.5 Replacing the backup battery An absolute encoder is used for the position detector, so the position must be saved with the backup battery when the power is turned OFF. The controller also uses a backup battery to save the program, etc. These batteries are installed when the robot is shipped from the factory, but as these are consumable parts, they must be replaced periodically by the user.

6Appendix 6 Appendix Appendix 1 : Configuration flag The configuration flag indicates the robot posture. For the 6-axis type robot, the robot hand end is saved with the position data configured of X, Y, Z, A, B and C. However, even with the same position data, there are several postures that the robot can change to. The posture is expressed by this configuration flag, and the posture is saved with FL1 in the position constant (X, Y, Z, A, B, C) (FL1, FL2).
