2. How to Save Data

2.4 Notes
Note on transferring data and writing it to the flash memory:
Never turn off the main power while data is still being transferred or written to the flash
memory. The data may be lost and the controller operation may be disabled.
Note on saving parameters to a file:
Encoder parameters are saved in the EEPROM of the actuator’s encoder (unlike other parameters, they
are not stored in the controller’s EEPROM). Therefore, encoder parameters are loaded from the encoder’s
EEPROM to the controller after the controller power is turned on or a software reset is executed. For this
reason, saving controller parameters to a file after the controller power has been turned on (or software
reset has been executed) without the actuator (encoder) connected to the controller will create a file
containing invalid encoder parameters.
Note on transferring a parameter file to the controller:
When a parameter file is transferred to the controller, the encoder parameters in the file will be transferred
to the encoder’s EEPROM (excluding manufacture information and function information). Therefore,
transferring to the controller a parameter file that has been read from the controller after the controller was
started without the actuator connected will write invalid encoder parameters to the encoder’s EEPROM.
(This applies when the file is transferred to the controller to which the actuator is currently selected.)
Save parameters to a file in a condition where the controller is connected to the actuator.
Note on the increased number of position:
The number of position data for the X-SEL-P/Q, PX/QX controller (w/gateway function) compatible with
increased memory has been increased to 20000.
Please be noted as follows.
* When using a memory backed up by battery (or parameter No.20=2), a memory backed up by battery
will be used when the conserved region has position No. 1-10000, and the main CPU flash ROM will be
used when it has position No. 10001-20000. Therefore, the data of position No. 1001-20000 will be
cleared if the power is turned off or the software is reset without writing to the flash ROM. Then next
time the power is turned on, the data from the previous writing to flash ROM will be loaded. To retain the
data, write it to the flash ROM. When a memory backed up by battery is not used (or parameter No.
20=0), the conserved region of all the position data No.1-20000 will be the main CPU flash ROM. Write
it to the flash ROM if you wish to retain the data.
