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.
