TRANSPORTATION & INSTALLATION MANUAL
2.6 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 the origin will be lost.
Also, if the battery voltage for backup of the X8HC printed board SRAM of the
controller has dropped, absolute position data set by the user will be lost. To avoid
this, replace each battery on a regular basis.
If the battery master power voltage has dropped, an alarm of level 1 as shown below
occurs. When this happens, replace the battery immediately.
Error code Descriptions
1–049 Axis1 Battery alarm
1–065 Axis2 Battery alarm
1–081 Axis3 Battery alarm
1–097 Axis4 Battery alarm
1–113 Axis5 Battery alarm
1–129 Axis6 Battery alarm
1–145 MAIN Battery alarm
If the master power voltage has dropped further, an alarm of level 8 as shown below
occurs. When this happens, replace the battery with a new one and adjust the origin
of the robot, if shifted, because there is a fear that the position encoder backup data
has been lost.
