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 6-277).

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.
