5-7-2 Procedure for Saving Data

Using SAVE DATA
114
Data transferred to the Position Control Unit will be erased either when the
power to the Programmable Controller is turned off or when the Unit is restarted.
To preserve the data that has been transferred, it must be saved in the Position
Control Unit's flash memory. Once it has been saved, it can be read out and used
the next time the power to the Unit is turned on or restarted. When the data is
saved, all data including parameters existing at that point in time are saved.
Note 1. Do not turn off the power or restart the Unit while data is being saved. It may
cause a failure in the Position Control Unit's internal flash memory, or cause
the Unit to operate abnormally.
2. If a failure does occur in the flash memory, a flash memory error (error code
9300) will be generated when data is saved. Saving data can take as long as
30 seconds.
3. Only save data when all axes are stopped and no other commands are
being executed. Otherwise the data will not be saved, and a multiple start
error (error code 8000) will result.
The contents of the PCU's internal memory are lost when the power supply is
turned off or when the PCU is restarted. By saving the contents of the internal
memory to the flash memory, parameters and other data can be retained.
The following types of data can be saved in the flash memory:
• Axis parameters
• Positioning sequences
• Speeds
• Acceleration and deceleration times
• Dwell times
• Zones
Note The data for the number of axes for the particular Position Control Unit being
used is all saved at once.
Parameters and other data that have been saved to flash memory are read to the
PCU's internal memory when the PCU is powered up or restarted. If the parame-
ters or other data are corrupted at that time, a parameter destruction error (error
code 0001) or data destruction error (error code 0002) will be generated and the
PCU will be started up using the initial values (i.e., the factory settings) or the
parameters and data that had been saved prior to the last save to flash memory.
If parameters or data are lost, no operation other than data transfer or data
saved can be received. After transferring the data, save the data and turn the
power off and then on again, or restart the Unit.
Use either the SAVE DATA Bit in the operating memory area (word n+1, bit 14) or
use the NC Support Tool.
Turning the SAVE DATA Bit (word n+1, bit 14) from OFF to ON will write the data
to the flash memory.
