Identifying code
of the inverter
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”.
The encoding rules for device codes (corresponds to identifying code 2103H of the inverter)
GD100 simple vector inverter
10.4.5 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.
A non-integer can be timed by a multiple to get an integer and the integer can be called
