Parameter
● 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).

Tab. 6-92: Description of the query message
The normal response data
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).

Normal Response (Response message):
Same data as the query message.
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.

Description
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) + 40001
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 fixed
to 2 bytes.
