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

10.4.6 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 times into 5012,
so hex 1394H can be used to express 50.12.
A non-integer can be timed by a multiple to get an integer and the integer can be called fieldbus ratio
