(vii) Writing data to multiple registers [10h]
This function writes data to sequential registers.
(Example)
When setting "3,000 Hz" 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".

*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.
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."
(viii) Exception response
The master system requests the inverter (slave) to return a response upon reception of a query other than
broadcasted queries. The inverter must return the response that matches the query it has received.
However, if an error is found in a query, the inverter will return an exception response.
The exception response consists of the following fields:
Details of the field configuration are described below. The exception response in reply to a query includes
a function code that is the sum of "80h" and the function code specified by the query. The exception code
in the exception response indicates the content of the error.

Code
An unsupported function is specified.
01h
The specified address is not found.
02h
The specified data has an unacceptable format.
03h
The data to be written to a register exceeds the range of inverter
21h
specifications.
The inverter restricts the execution of the specified function:
- Rewriting a register that cannot be rewritten during the operation
- Issuing an Enter command during the operation (in undervoltage
22h
status)
- Writing to a register during tripping (because of undervoltage)
- Writing to a read-only register (coil)
