Saving Data

Saved to
CX-Position's
FD or HD
3. Downloading and uploading using CX-Position. (Refer to 5-7 Transferring
Data with CX-Position.)
Parameters and data created with CX-Position, as well as the PCU's inter-
nal data, can be uploaded/downloaded between the PCU and CX-Position.
Note Be sure to use only parameters and data for which correct operation is possi-
ble.
The transferred data is written to the PCU's memory, but it will be lost if the
power is turned OFF or if the PCU is restarted from the CPU Unit. To keep the
transferred data permanently in the PCU, it is necessary to save it to the
PCU's flash memory using the operating memory area. For details on saving
data to flash memory, refer to 5-6 Saving Data. Once saved, the data is kept in
the flash memory of the PCU, and is used the next time the power is turned
ON or the PCU is restarted. If the data is merely transferred without being
saved, when the power is turned OFF or the PCU is restarted, the contents of
the memory will revert to whatever was saved previously.
CPU Unit
Note 1. Data saved to flash memory is automatically read to the internal memory
at power up or restart. The axis parameters that are read to the internal
memory can be set to either the axis parameters saved in flash memory or
to the axis parameter settings in the CPU Unit's DM Area.
2. Do not turn OFF the power or restart the PCU while the data is being
saved. It can cause a fault in the PCU's internal flash memory. Saving data
may take up to 30 seconds.
3. Data cannot be saved while a data transfer is in progress or while the PCU
is busy. Any attempt to execute a save will result in a multiple start error
(error code 8000).
