R/W characteristics means the function is with read and write characteristics. For example,
"communication control command" is writing chrematistics and control the VFD with writing
command (06H). R characteristic can only read other than write and W characteristic can only
write other than read.
Note: when operating on the VFD with the table above, it is necessary to enable some
parameters. For example, the operation of running and stopping, it is necessary to set P00.01
to communication running command channel. And when operate on "PID given", it is
necessary to set
P09.00 to "Modbus communication setting"."

Note:
The code is consisted of 16 bit which is high 8 bits and low 8 bits. High 8 bits mean the motor
type series and low 8 bits mean the derived motor types of the series.
7.4.3 Fieldbus ratio values
The communication data is expressed by hex in actual application and there is no radix point
in hex. For example, 50.12Hz cannot be expressed by hex so 50.12 can be magnified by 100
