*1. There is no response for broadcasting.
*2. Since the change data comprises both MSB and LSB as a set, make the byte to be an even number by adding
1, even if the byte that actually needs to be changed is an odd number.
Refer to "<Exception Response>" below if writing into multiple coils cannot be performed normally.
<Writing Into Multiple Holding Registers [10h]>
Writes into consecutive multiple holding registers.
(Example)
Set 1st acceleration time 1 (F002) to "3000 sec." for the Inverter with slave address 1.
The data resolution of the holding registers "0024h, 0025h" of acceleration time 1 (F002) is 0.01
seconds. To set 3000 seconds, set change data to "300000 (493E0h)".

*1. There is no response for broadcasting.
*2. Specify the number of bytes to be changed, not the number of holding registers.
Refer to "<Exception Response>" below if writing into the multiple holding register cannot be per-
formed 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.
