8-7 Saving Data
CJ Position Control Units OPERATION MANUAL (CJ1W-NC214/234/414/434)
Data to be Saved
The data which you transferred to the PCU is lost if you turn OFF the PLC power supply or
restart the PCU. Save the transferred data to the internal flash memory on the PCU to keep
the data. Once you save the data, you can then use the saved data when you turn ON the
power supply or restart the PCU next time.
When you execute the data save, you save all parameters and data as of that time.
The content of the internal memory on the PCU is lost when you turn OFF the power supply or
restart the PCU.
You can save the content of the internal memory to a flash memory and save the parameters
and data by performing the data save operation.
The data below are saved to a flash memory.
All data for the number of axes of the PCU is saved together.
The parameters and the data that are saved to a flash memory are written into the internal
memory on the PCU when you turn ON the power supply or restart the PCU.
At that time, if the parameters and the data on the flash memory are damaged, a Special I/O
Unit memory error (user data) (error code: 0010) occurs, and the PCU starts up with the default
settings (default setting).
Do not turn OFF the power supply or restart the PCU while data save is in progress. It may cause
a failure of the internal flash memory on the PCU. Consequently, you may not be able to run the
PCU properly.
If you save data when there is a flash memory failure, a Special I/O Unit memory error (user data)
(error code: 0010) occurs. It may take up to 30 seconds to save data.
progress. If you execute the operation in any other conditions, the data save will not be executed,
and a duplicate start error (error code: 8200) occurs.
