Functions
*1. There is no response for broadcasting.
*2. Specify the number of bytes to be changed, not the number of holding registers.
*3. Note that the holding register start address is "1013h", which is smaller by 1 than the register number "1014h".
Refer to "<Exception Response>" below if writing into the multiple holding registers cannot be
performed normally.
<Exception Response>
The master requires a response for a query except for broadcasting. Though the Inverter should
return a response corresponding with the query, it returns an exception response if the query has
an error.
The exception response has a field configuration shown in the following table.
The detailed field configuration is shown on the next page. The function code of the exception re-
sponse is the value of the query function code with 80h added. The exception code shows the cause
of exception response.
