Enter Command Chapter 7-5

7-5 Enter Command

The Enter command is used for copying parameter set values that have been

written through communications in and after register 0101 Hex of the 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.

Note The Enter command is not accepted while the Inverter is running. Be sure to

issue the Enter command while the Inverter is not running.

DSR Message of Enter Command

• The Enter command is issued in response to the DSR message (with a

function code 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 (in and after register 0101 Hex) are stored

in the EEPROM with the Enter command.

The RUN command (in register No. 0001 Hex) is in the RAM area. The

frequency reference (in register 0002 Hex) or any other data in registers

with a number up to 003D Hex is also in the RAM area. Therefore, the

EEPROM does not store these parameters.

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.
