( 4 ) Additional Information
[ a ] Writing Parameters to EEPROM
The procedure to write parameters to the parameter storage memory in the Inverter (EEPROM) is given in the follow-
ing figure.
The parameters are first written to work memory in the Inverter with the ICNS-WR system function. To write those
parameters to EEPROM, you must use the Write Enter command that is shown in the following figure.
[ b ] Executing the Write Enter Command
To execute the Write Enter command, use the ICNS-WR function to write data of 0 to the reference “FEED”.
