Chapter 8 Communication Functions
8 - 15
(G) Write in Holding Registers [10h]
This function writes data in consecutive holding registers. An example follows:
 Write “3000 seconds” as the first acceleration time 1 (F002) in an inverter having a slave
address “8.”
 This example uses change data “300000(493E0h)” to set “3000 seconds” as the data resolution
of the registers “1103h” and “1104h” holding the first acceleration time 1 (F002) is 0.01 second.

Note 1: Broadcasting is disabled.
Note 2: This is not the number of holding registers. Specify the number of bytes of data to be
changed.
Note 3: The PDU Register Number are addressed starting at zero. Therefore register numbered
“1103h” are addressed as “1102h”. Register address value (transmitted on Modbus line)
is 1 less than the Register Number.
When writing in selected holding registers fails, see the exception response.
