Toshiba Industrial Robot TH180

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.;

The memory equipped on the X8GC printed board of the; robot controller is backed up by a lithium battery to save the; data. Replace the battery every five (5) years.

The lithium battery will turn its life when used for a; predetermined time. If it is used, neglecting the life, the; battery voltage will drop to below the voltage required for; keeping the memory data, resulting in the data being lost; and faults caused by leakage of the battery liquid.

If the following alarm has occurred, replace the battery with; a new one.

• 1–145 MAIN Battery alarm (Alarm code 1-45)

Note: The battery life is ten (10) years at the room; temperature. As it differs with the external environment; such as operating temperature and humidity, we; recommend to replace the battery every five (5) years.

Only the battery shown in Table 3.2 should be used. As this; is an exclusive battery, contact Toshiba Machine at order; entry.

[Battery replacement procedures]

1) If the battery is to be kept removed for more than one (1); minute, copy all programs and various parameters stored in; the internal memory to the personal computer. In the worst; case, all memory data are lost.

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.;

Replacement of Position Detector (or Encoder) Batteries

To back up the data of the position detector attached to; each motor, batteries are used.

The battery life changes with the controller power OFF time.; When the controller is operated at a rate of eight (8) hours; per day, the calculated life is approximately two (2) years; which may vary, however, with the operating condition,; ambient temperature, etc. Be sure to replace the batteries,; therefore, at the time of yearly inspection. For the replacing; procedures, see the descriptions below.

Note: The battery alarm comes in the two (2) types; battery; warning alarm (Battery alarm) and battery error (Encoder; abnormal).

Normally, when the battery warning alarm has generated,; the battery error can be avoided by replacing the batteries; with new ones. When this happens, however, the battery; error(Encoder abnormal) will occur within one (1) month; after generation of the battery warning alarm.

If the time of battery replacement is delayed, the battery; error will generate and the robot may not be moved at all.

Once the battery error has been detected, the robot enters; an emergency stop state, and reset of the encoder error is; required.

(For how to reset the encoder error, see the Appendix B of; this manual. Be sure to replace the batteries at the time of; annual inspection.
