Caution
xx Notes on transferring data and writing it to the flash memory
Never turn OFF the main power while data is being transferred or written to the flash
memory, because data may be lost and the controller will no longer be able to operate.
x Notes on saving parameters to a file
Encoder parameters are stored in the EEPROM of the actuator’s encoder. (Unlike
parameters of other types, these parameters are not stored in the controller’s
EEPROM.) When the power is turned ON or software is reset, encoder parameters
are loaded from the EEPROM to the controller.
Accordingly, if parameters are saved to a file after the controller power was turned on
(or software was reset) while the actuator (encoder) was still not connected, the
encoder parameters in this file will become invalid.
x Notes on transferring a parameter file to the controller
When a parameter file is transferred to the controller, encoder parameters are
transferred to the encoder’s EEPROM (excluding manufacturing information and
function information).
Accordingly, if a parameter file is read and transferred to the controller after the
controller power was turned on while the actuator was still not connected, invalid
encoder parameters will be written to the encoder’s EEPROM (as they are transferred
to the controller to which the actuator is connected).
To save parameters to a file, do so while the actuator is connected.
