Communication Function
Writing Into Multiple Holding Register [10h]
Writes into consecutive multiple registers.
Example) Set Acceleration Time Setting 1 (F002) to "10 s" for the Inverter whose slave
address is "1".
Since holding registers "1103h and 1104h" used for Acceleration Time Setting 1 (F002) have a
data resolution of 0.01 s, the data to be written should be "1000 (0000 03E8h)" when setting 10 s.
(Register address) = (Register number) − 1
0000 03E8h → 1000d → 10.00 s
Query:
Response:
*1. There is no response for broadcasting.
*2. Note that the holding register start address is "1102h", which is smaller by 1 than the register number
"1103h". The register number less 1 corresponds to the register address.
*3. Specifies the number of actual bytes to change to, not the number of holding registers.
Refer to "Exceptional Response" on page 6-18 if the writing into the multiple registers cannot
be performed normally.
