9.4.4 Command code: 10H, continuous writing
The command code 10H is used by the master to write data to the VFD. 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
VFD 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 VFD.
