R
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 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”.

Goodrive100 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
Goodrive100 vector inverters.
7.3.5 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.
