Write in Holding Register [06h]:
This function writes data in a specified holding register. An example follows:
 Write “50Hz” as the first Multi-speed 0 (A020) in an inverter having slave address
“5.”
 This example uses change data “500(1F4h)” to set “50Hz” as the data resolution of
the register “1029h” holding the first Multi-speed 0 (A020) is 0.1Hz

Note 1: No response is made for a broadcasting query.
Note 2: The PDU Register Number are addressed starting at zero. Therefore register
numbered “1029h” are addressed as “1028h”. Register address value
(transmitted on Modbus line) is 1 less than the Register Number.
When writing in a selected holding register fails, see the exception response.
