GD310-UL series VFD Communication protocol
-203-
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 VFD)
High 8 bit Meaning Low 8 bit Meaning
01 GD
0x08 GD35 vector VFD
0x09 GD35-H1 vector VFD
0x0a GD310 vector VFD
0x0b GD100 simple vector VFD
0x0c GD200 universal VFD
0x0d GD10 mini VFD
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 cannot 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
“hibernation restore delay
time
” is 5.0 (5.0=50÷10).
If Modbus communication is used to control the hibernation restore delay time as 5.0s. Firstly, 5.0 can
be magnified by 10 times to integer 50 (32H) and then this data can be sent.
