Note Communications error details are stored until an fault reset is input (you can also reset while the Unit is operating).
Broadcast Data
The following table shows the broadcast data. You can also write this 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 communications, the parameters are
temporarily stored in the parameter 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: ENTER commands that enable parameter data in RAM, and
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 0910H.
Register No.

Write parameter data to EEPROM
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 thousand. 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).
