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 operate 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 set P00.02 to MODBUS communication channel. And when operate
on "PID reference", it is necessary to set P09.00 to "MODBUS communication setting".
The encoding rules for device codes (corresponds to identifying code 2103H of the VFD)
