Note Communications error details are stored until an error reset is input (you can also reset while the Unit is operating). Communications error details can
also be read by using the register numbers given in the Register column in the U: Monitor parameter table.
Broadcast Data
The following table shows the broadcast data. This is write data only.
Register Address

0002H
Note Bit signals not defined in the broadcast operation signals use local node data signals continuously.
nENTER Command
When writing parameters to the Inverter from the PLC using RS-422A/485 communications, the parameters
are temporarily stored in the parameter data area in the Inverter. 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 Inverter 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.

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 Inverter 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).
