<Writing Into Multiple Holding Register [10h]>
Writes into consecutive multiple holding registers.
(Example)
Set acceleration time 1 (F002) to "3000 sec." for the Inverter with slave address 1.
The data resolution of the holding register "1103h, 1104h" of acceleration time 1 (F002) is 0.01 sec-
onds. To set to 3000 seconds, set data to "300000 (493E0h)".
If writing into multiple holding registers cannot be performed normally, refer to the "Exception
Response" section.
<Exception Response>
The master requires the response for a query except for broadcast. Though the Inverter should re-
turn a response corresponding with the query, it returns an exception response if the query has an
error.
The exception response has the field configuration shown in the following table.
