Write multiple holding register data (H06 or 06)
You can write the description of 1) system environment variables and 4) inverter parameters assigned to the
holding register area (refer to the register list (page 215)).

Description of normal response
1) to 4) (including CRC check) of the normal response are the same as those of the query message.
No response is made for broadcast communication.
Example) To write 60Hz (H1770) to 40014 (running frequency RAM) at slave address 5 (H05).

For broadcast communication, no response is returned in reply to a query. Therefore, the next query must be made
when the inverter processing time has elapsed after the previous query.

Set the address to which the message will be sent. Setting of address 0
enables broadcast communication
Set H06.
Set the address of the holding register to which data will be written.
Register address = holding register address (decimal)
For example, setting of register address 0001 writes data to the holding
register address 40002.
Set the data that will be written to the holding register. The written data is
always 2 bytes.
