■4. Precautions for QCPU
The restoration to QCPU with the factory-settings or whose memory is formatted is available only in the following
cases.
• For a single CPU system: When the connection type is the bus connection or direct CPU connection
• For a multiple CPU system: When the connection type is the direct CPU connection
However, in a multiple CPU system which includes a QCPU with the factory-settings or whose memory is formatted,
batch restoration to multiple controllers cannot be performed.
Restore each controller with the following procedure.
■5. Precautions for MELSERVO-J4 series
(1) Restoration procedure
Use the rotary switch of a servo amplifier to set the network number and station number that are specified in the
controller list file.
For the setting method, refer to the manual of the servo amplifier used.
After the setting, turn off and then on the servo amplifier.
Perform restoration on the GOT.
(2) Engineering tool
The GOT backup/restoration function backs up the data of a servo amplifier to the data storage installed in the GOT.
You can read the data from the data storage by using the engineering tool (MR Configurator2 Ver1.52E or later).
However, the GOT backup/restoration function cannot restore the data edited with the engineering tool.
(3) Backup
The GOT collectively backs up the data of all the MELSERVO-J4 series servo amplifiers that are specified by their
network numbers and station numbers in the controller list file.
(4) Restoration
To restore data to MELSERVO-J4 series servo amplifiers, select target servo amplifiers based on the network
numbers and station numbers. All the data for the selected servo amplifiers are restored.
In the absolute position detection system, if you replace a servo amplifier and then restore data to the new one, set
the home position again.
After restoration is performed, turn off and then on the servo amplifier.
(5) Backup/restoration availability
The backup/restoration is available in the cases shown below.

■6. Precautions for motion controller CPUs
(1) OS for motion controller CPU
The OS for the motion controller CPU cannot be backed up or restored.
For backing up or restoring setting data for the motion controller CPU, install an appropriate OS on the motion
controller CPU in advance.
(2) Backup/restoration target
The GOT backs up or restores data stored in the SRAM built in the motion controller CPU, regardless of the
operation mode.
For writing data to the FLASH ROM built in the motion controller CPU, restore the data to the SRAM, and then write
the data in the SRAM to the FLASH ROM with MT Developer.
(3) Backup
For backing up data for controllers including the motion controller CPU, do not set the motion controller CPU to the
installation mode.
When the motion controller CPU is set to the installation mode, the GOT does not back up data for the motion
controller CPU. (The GOT backs up data for the other controllers on the same base unit.)
