Command Code: 10H, Continuous Writing; Data Address Definition - IMO HD2 IP Series Instruction Manual

HD2 IP55 High-ingress Protection Series Inverter

9.4.4 Command code: 10H, continuous writing

The command code 10H is used by the master to write data to the inverter. The quantity of data
to be written is determined by "Data quantity", and a maximum of 16 pieces of data can be
written.
For example, to write 5000 (1388H) and 50 (0032H) respectively to 0004H and 0005H of the
inverter whose slave address is 02H, the structure of the frame is described in the following
table.

9.4.5 Data address definition

This section describes the address definition of communication data. The addresses are used
for controlling the running, obtaining the state information, and setting related function
parameters of the inverter.
9.4.5.1 Function code address representation rules
The address of a function code consists of two bytes, with the MSB on the left and LSB on the
right. The MSB ranges from 00 to ffH, and the LSB also ranges from 00 to ffH. The MSB is the
hexadecimal form of the group number before the dot mark, and LSB is that of the number
behind the dot mark. Take P05.06 as an example, the group number is 05, that is, the MSB of
the parameter address is the hexadecimal form of 05; and the number behind the dot mark is
06, that is, the LSB is the hexadecimal form of 06. Therefore, the function code address is
