[Pr. PN20_Parameter automatic backup update interval (**PABI)]
Initial value
0 [h]
Set the backup interval for a parameter automatic backup to be performed when the specified time passes on an hourly basis.
When the value is set to "0", a parameter automatic backup when the specified time passes is not performed.
When the set backup time is reached while the servo amplifier is not connected to a controller, and the power of the servo
amplifier is cycled, even if a connection is established with the controller, backup operation is not immediately performed.
There is a limit to the number of times to write to the data memory of the controller. When the number of connected axes is
large and when backup operation is performed at short intervals, the maximum memory writing frequency of the controller
may be reached earlier than the operating life.
Therefore, be careful about the frequency of writing when performing a backup.
You can check the frequency of writing so far with the special register in the CPU module.
For details, refer to the CPU module user's manual.
The estimated write interval per number of connected axes is as follows.
1 to 16 axes: Once every hour
17 to 32 axes: Once every two hours
33 to 64 axes: Once every four hours
65 or more axes: Once every six hours
Ex.
When "2" is set for the setting value of this servo parameter
After the power is turned on, whether there is any difference between the previously delivered servo parameter and the
current servo parameter is checked every two hours. When there is a difference, backup operation is performed.
