(vii) Writing data to multiple registers [10h]
This function writes data to sequential registers.
(Example)
When setting "3,000 s" as the Acceleration (1) time (F002) in the inverter at slave address "1":
Since register "1103h" and "1104h" to store the Acceleration (1) time (F002) have a data resolution of 0.01 seconds,
specify "300000" (493E0h) as the updating data to set "3,000 seconds".
If the function to write data to multiple registers cannot be executed normally, the inverter will return an exception
response. For details, see Item (viii), "Exception response."

*1 If this query is broadcasted, no inverter will return any response.
*2 Note that the starting register address is 1 less than the actual address of
the register to which the data is to be written first.
*3 As the number of bytes, do not specify the number of registers but the
number of bytes to be actually updated.
