Note:
•
You can write the EEPROM to the drive a maximum of 100,000 times. Do not frequently execute the Enter
command (0900 (Hex.)) that is written to EEPROM. When the command data or broadcast message is
transmitted to the drive, the Enter command is not necessary.
•
Parameter data cannot be written to EEPROM during undervoltage, even using 0900 (Hex.).
•
If undervoltage occurs when a making several parameter changes issued with a single ENTER command, the
writing process may be aborted before all of the new changes have been written. Because all of the data has
not yet been written, the EEPROM data error
CPF06
will be displayed the next time power to the drive is
cycled. To prevent
CPF06
, wait approximately 5 seconds after issuing the ENTER command before shutting
off drive power.

When you change the parameter settings
Upper and lower

related parameters
Not affected. The settings of related
parameters remain unchanged. They must be
changed manually, if needed.
Automatically changes the default settings
for the related parameters.
Fault detection when
you set more than
one parameter
Accepts and responds as usual to correct
setting data if the data contains parameter
setting errors. The drive discards the
disabled setting data, but will not return an
error message.
Error occurs if only one setting is invalid.
All data sent are discarded. The drive
