controller; it is necessary to use the correct combination of the robot body and robot
controller.
To replace the robot body or robot controller only, perform backup/restore of
predictive maintenance information to migrate the predictive maintenance
information.
• In order to prevent writing backup data to a different robot, an error (H.7101) occurs
when the serial number of the robot is different from the backup data value when
restoring.
• When the serial number of the connected robot was changed, an error (H.7100) is
output upon power on to notify that effect in order to prevent the occurrence of
unmatched predictive maintenance information when exchanging robot.
• When there is no backup data, all consumption degrees can be reset by performing
mechanism replacement of maintenance reset. However, in that case, the
consumption degree calculation result cannot be the correct value. (Refer to "11.2
Maintenance Reset".)
• After replacing the robot controller, if you did not restore the predictive maintenance
information or if you restored it a long time after backup was performed, the
consumption degree calculation result cannot be the correct value.
• Perform backup/restore between robot controllers having the same software
version. If the version is different, there is a possibility an error may occur when
restoring.
