9-4 Saving a Change to Holding Register
(Enter Command)
The Write to Holding Register (06 hex) or Write to Consecutive Holding Registers (10 hex) function is
used to enable the new data. However, the new data is not stored in the EEPROM of the inverter and is
restored to the previous value when the inverter power supply is shut off.
To store a change to holding registers in the inverter’s EEPROM memory, issue the Enter command
according to the following procedure. In addition, after changing a control parameter, you need to recal-
culate the motor parameters. In this case, also use the Enter command to execute recalculation.
