Saving Data
Data transferred to the PCU will be erased either when the power to the Pro-
grammable Controller is turned OFF or when the PCU is restarted. To preserve
the data that has been transferred, it must be saved in the PCU’s flash memory.
Once it has been saved, it can be read out and used the next time the power to
the PCU 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 PCU while data is being saved. It
may cause a failure in the PCU’s internal flash memory, or cause the PCU 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.
5-6-1 Flash Memory
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 PCU 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 PCU.
5-6-2 Data Saving Procedure
Data can be saved using either the SAVE DATA Bit in the operating memory area
or using CX-Position. For details of saving data using CX-Position, refer to the
CX-Position’s operation manual.
Beginning Words of Operating Memory Area, Operating Data Area, and
Parameter Areas
The beginning words of the operating memory area, the operating data area and
common parameter area used for a PCU are determined (or set) according to
the following.
