• Content of normal response
With a normal response, the content is the same as a to d (including the CRC check) query messages.
In the case of broadcast communication, no response is returned.
Example) Write 60Hz (H1770) to 40014 (set frequency) of slave address 5 (H05).

NOTE
• With broadcast communication, no response is generated even if a query is executed, so when the next query is made, it
must be made after waiting for the inverter data processing time after the previous query is executed.

Set the address to send messages to. Setting "0" enables broadcast communication.
Set H06.
Set the address from data is written to the holding register.
Register address = holding register address (decimal) - 40001
For example, when register address 0001 is set, data is written to holding register
address 40002.
Set the data to write to the holding register. Write data is fixed at 2 bytes.
