Write multiple holding register data (H06 or 06)
You can write the description of system environment variables and inverter parameters
assigned to the holding register area. (Refer to the register list on page 6-236).
Query message
Normal response (Response message)
The normal response data to (including CRC check) of the normal response are the same
as those of the query message. No response is made for broadcast communication.

Message Description
Slave Address
Set the address to which the message will be sent. Setting of address 0
enables broadcast communication.
Function Set H06.
Register Address
Set the address of the holding register to which data will be written.
Register address = holding register address (decimal) + 40001
For example, setting of register address 0001 writes data to the holding
register address 40002.
Preset Data
Set the data that will be written to the holding register. The written data is
fixed to 2 bytes.

NOTE 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.
