Broadcast Data

The following table shows the broadcast data.
Register
Address
Note: Bit signals not defined in the broadcast operation signals use local node data signals continuously.
Note: Refer to register 000FH, bits 000CH through 000FH, in Table D.4 when using bits 000CH through

Enter Command

When writing parameters to the Drive from the master using Modbus communication, the parameters are temporarily stored in
the constant data area in the Drive, and they will be lost if power to the Drive is shut OFF. To enable these parameters in the
parameter data area, which is retained when power is removed, use the Enter command.
There are two types of Enter commands:
1. Enter command that enables parameter data in RAM.
2. Enter command that writes data to EEPROM (non-volatile memory) in the Drive and also enables data in RAM.
The following table shows the Enter command registers. Enter command registers can only be written.
The Enter command is enabled by writing 0 to register number 0900H or 0910H.
Register No.

000FH of broadcast data register 0001H.
0900H 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 command (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).
