8-6 Saving a Change to Holding Register
(Enter Command)
The Write to Holding Register (06 hex) or Write to Consecutive Holding Registers (10 hex or 17 hex)
function is used to enable new register 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.
Use the Write to Holding Register (06 hex) command to write data to the holding register for the Enter
command (0900 hex). Below are the values to be written to the holding register (0900 hex).
*1. When the motor parameter initialization is executed, the parameters listed below are initialized to the default
data.

Precautions for Correct Use
• After receiving the Enter command, the inverter returns a response to the host and writes the
value to the EEPROM memory. You can monitor the during data write signal (Coil No. 0049
hex) to check whether the data is written.
• Since the inverter’s EEPROM memory has a limit for the number of rewrites (approximately
100,000 times), the inverter life may be shortened if the Enter command is frequently used.
