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 operating 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 P00.01 to
communication running command channel and set P00.02 to MODBUS communication channel.
And when operate on “PID given”, it is necessary to set P09.00 to “MODBUS communication
setting”.

01 Astraada 06 Astraada DRV-24 Vector Inverter
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. For example, 0110H means
Astraada DRV-24 vector inverters.
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 can not 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 values.
The fieldbus ratio values are referred to the radix point of the setting range or default value in the
function parameter list. If there are figures behind the radix point (n=1), then the fieldbus ratio
value m is 10
n . Take the table as the example:
