Broadcast Data
The following table shows the broadcast data.

Note: Bit signals not defined in the broadcast operation signals use local node data signals continuously.

Enter Command

When writing parameters to the Drive from the PLC using Modbus communication, the parameters are temporarily stored in
the constant data area in the Drive. To enable these parameters in the parameter data area, use the Enter command.
There are two types of Enter commands:
1. Enter commands that enable parameter data in RAM
2. Enter commands that write data to EEPROM (non-volatile memory) in the Drive at the same time as enabling data in RAM.
The following table shows the Enter command data. Enter command data can only be written.
The Enter command is enabled by writing 0 to register number 0900H or 0901H.
Register No.
IMPORTANT
Broadcast Data Can Be Written (fuNction Code 06H/10H) only.

Write parameter data to EEPROM
0910H
Parameter data is not written to EEPROM, but refreshed in RAM only.
The maximum number of times you can write to EEPROM using the Drive is 100,000. Do not frequently
execute Enter commands (0900H) written to EEPROM.
The Enter command registers are write-only. Consequently, if reading these registers, the register address
will become invalid (Error code: 02H).
