Automatic Backup Function

9.3.1
Automatic Backup Function
With the automatic backup function, the data saved in the NX 100 such as system setting or
operational condition are collectively backed up in the CompactFlash which is inserted in the
programming pendant.
In case of an unexpected trouble such as data loss, the backup data saved in the Compact-
Flash by the automatic backup function can be loaded to the NX100 memory to restore the file
data.
The automatic backup function is enabled only while the NX100 power supply is ON in nor-
NOTE
mal mode whereas it isn't while in the maintenance mode or the power supply is OFF.
Outline
The automatic backup function saves the internally stored data in a single file in advance for
the smooth restoration from unexpected troubles of the NX100.
The teaching operation is one of the factors that changes the internally stored data. Thus, a
mode which backs up the latest data after the teaching operation is prepared. To confirm the
termination of the teaching operation, check the mode key whether it is changed from teach
mode to play mode.
Other than the teaching operation, the present position of the robot or the value of a variable
can be pointed out as the factors to change the internally stored data. These data, however,
are changed after each operation and have very little need to be retained permanently.
Accordingly, backing up these data at regular interval should be well enough to operate and
the mode to back up the data at regular interval is also prepared.
Furthermore, the mode to back up the data when starting up the NX100 and when inputting
signals are also available for some specific versions.
With the automatic backup function, all the part where the internal data is stored in the physi-
cal memory area is collectively saved. If there is any data which is in the middle of changing
while executing the automatic backup function, the data might not be usable for restoration
because of its inconsistency. Therefore, the function is terminated with an error during the
play back operation or while the manipulator is in motion so that the automatic backup cannot
be operated. Set the automatic backup function to be executed while the manipulator is not in
the playback status and while the manipulator is stopped.
