7-4 Enter Command
The Enter command is used for copying parameter set values that have
beenwrittenthroughcommunicationsinandafterregister0101Hex ofthe
RAM area to the EEPROM of the Inverter. This is done so that the
EEPROM can maintain the parameter set values.
By issuing a DSR message to write data, the data is written to the RAM
area of the Inverter. This data will be lost when the Inverter is turned OFF.
Issue the Enter command to store in the EEPROM of the Inverter the
parameter set value that has been written through communications.

the Enter command while the Inverter is not running.
H DSR Message of Enter Command
·The Enter command is issued in response to the DSRmessage (witha functioncode
of 10 Hex) to write data.
·By writing data 0000 Hex to be sent to register 0900 Hex, the Inverter copies to the
EEPROM all parameter set values that the Inverter has received.
Note 1. Only the parameter constants (inandafterregister 0101 Hex) arestored inthe
EEPROM with the Enter command.
The RUN command (in register No. 0001 Hex) is in the RAM area. The fre-
quency reference (in register 0002 Hex) or any other data in registers with a
numberupto003DHexisalsointheRAMarea.Therefore,theEEPROMdoes
not store these parameters.
Note 2. Data can be written to the EEPROM a maximum of approximately 100,000
times. Therefore, be sure to reduce the number of Enter commands sent as
much as possible.
