8-3. Caution
Cautions in data transfer and flash writing
Never shut OFF the main power while the data is transmitting and writing into flash.
Data may be lost and controller may be rendered inoperable.
Cautions in storing parameters in a file
Encoder parameters are stored in EEPROM of the actuator’s encoder itself (not in
EEPROM within the controller, which is different from the other parameter types). When
the power is turned on or software is reset, encoder parameters are read from EEPROM
into the controller.
Therefore, if you store the parameters of the controller, which has been powered on
or of which software has been reset when the actuator (encoder) is not connected, in a
file, the encoder parameters stored in this file become invalid values.
Cautions in transferring a parameter file to controller
When the parameter file is transferred to the controller, the encoder parameters are
transferred to EEPROM of the encoder (excluding manufacturing information and
function information).
Therefore, if you transfer the parameter file read from the controller, which has
started up when the actuator is not connected, to the controller (which is connected to
the actuator), the encoder parameters of invalid values are written in EEPROM of the
encoder.
When storing the parameters in a file, do so when the actuator is connected.
