Position Detector Backup Batteries - Toshiba TH180 Instruction Manual

2.7

Position Detector Backup Batteries

The robot has batteries to back up positional information on position detectors in its
base. Unless the robot is used for a long period of time, the battery voltage will drop
and the positional data of origin will be lost.
Replace the batteries every year. It is recommended to replace the batteries at the
time of installation so that they can be replaced at regular inspection and maintenance.
Also, if the battery voltage for backup of the X8LC printed board SRAM of controller
has dropped, absolute position data set by the user will be lost. To avoid this, replace
the batteries on a regular basis.
If the master power voltage of the batteries has dropped, an alarm of level 1 as shown
below occurs first. When this happens, replace the batteries immediately. For the
battery replacement, see Para. 2.3.8 and 3.3.3 of the Maintenance Manual.
If the master power voltage has dropped further, an alarm of level 8 as shown below
occurs. When this happens, replace the batteries with new ones and perform
encoder error reset operation because there is a fear that the position encoder backup
data has been lost. For the encoder error reset operation, see Appendix B of the
Maintenance Manual.
