15.1.1 Common to preventive maintenance functions

Functions such as consumption degree calculation of the preventive maintenance function assume that
the same controller and the same mechanism are used.
When the serial number of the connected robot was changed, the error (H.7100) is output to notify that
effect upon power ON in order to prevent reliability of the preventive maintenance function from
decreasing after exchanging the robot or robot controller.
Also, in order to prevent writing backup data to a different robot, the error (H.7101) occurs when
attempting restoration if the serial number of the robot body is different from the backup data value, and
restoration cannot be performed.
Also, in case the backed up data format has been changed as a result of version upgrade of the robot
controller and it is attempted to write the old format data, error H.7102 is output to notify that effect.
