Toshiba Industrial Robot TH180

Cable ducts; (1) Make sure that any cable duct will not twist, bend or; crack; locally at the time of robot motion.

(2) Make sure that all connectors of the cable ducts are; tightened completely.

Make sure that the hand set flange bolts are tightened ; completely.

Make sure that the robot base installation bolts are; tightened; completely.

Make sure that each axis can move smoothly.

Change in positioning accuracy

Fill grease to the ball screw spline.

Lubrication of reduction gears

Fill grease to the reduction gears from the grease nipples.

Make sure that all cables and air tubes are in the good; state.

Replacement of position detector batteries

(Be sure to replace the batteries every year.)

Replace the position detector backup batteries (housed in; the; robot base unit). If the running time is long, battery; consumption is small. If the power OFF time is long, the; consumption is large. If the battery voltage drops, a battery; alarm occurs. Then replace the batteries immediately.;

Lubricated state of ball screw spline

Make sure that the ball screw spline (or tool shaft) is greased; completely and that no rust is developed on it.;

Apply the grease to the ball screw spline.

Move each axis by hand and make sure that it moves; smoothly.

(1) Make sure that each timing belt is not worn off or; cracked.

(2) Check each timing belt for tension.;

Cautions on Maintenance and Inspection

When performing inspection or maintenance of the robot,; strictly observe the following precautions to protect; yourself; and coworkers.

• Be sure to turn off the main power switch of the controller; before approaching the robot for maintenance and; inspection.
