01 Goodrive 06 Goodrive20 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 Goodrive20
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:
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.
After the inverter receives the command, it will change 50 into 5 according to the fieldbus ratio value and
then set the hibernation restore delay time as 5s.
Another example, after the upper monitor sends the command of reading the parameter of hibernation
restore delay time ,if the response message of the inverter is as following:
Because the parameter data is 0032H (50) and 50 divided by 10 is 5, then the hibernation restore delay time
is 5s.
