7-4-2 Data Write/Broadcast Data Write (Function Code: 10 Hex)
Settings and Response
• To write data to the Inverter, such as control I/O and parameter set value
data, issue the following DSR message.
• Consecutive data of a maximum of 16 words (32 bytes for 16 registers)
can be written per DSR message.
• The register number is allocated to each function item, such as control I/O
and parameter functions. The register number of each parameter is
indicated wherever the parameter is explained in this manual and in
Section 10 List of Parameters. For register numbers other than those of
parameters, refer to
7-7 Register Number Allocations in Detail
.
Note 1. A parameter corresponds to one register (one word), so the “number of
registers of write data” indicates the number of parameters to be written
(i.e., the number of consecutive registers beginning with the first register
number).
2. The “number of bytes of attached data” indicates the number of bytes of
data written to the registers attached from that point onwards. The number
of registers must equal the number of bytes divided by two.
