R/W
characteristics
Fault code 5000H 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 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 inverter)
Code high 8
bit
Meaning Code low 8 bit Meaning
01 GD
0x08 GD35 vector inverters
0x09 GD35-H1 vector inverters
0x0a GD300 vector inverters
0x0b GD100 simple vector inverters
0x0c GD200 general inverters
0x0d GD10 mini inverters
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 Goodrive200 vector inverters.
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 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:
If there is one figure behind the radix point in the setting range or the default value, then the
fieldbus ratio value is 10. if the data received by the upper monitor is 50, then the
