Goodrive300-LIFT series inverter Communication protocol
-123-
T1-T2-T3-T4 (transmission time of 3.5 bytes)
T1-T2-T3-T4 (transmission time of 3.5 bytes)
The RTU response command is:
T1-T2-T3-T4 (transmission time of 3.5 bytes)
T1-T2-T3-T4 (transmission time of 3.5 bytes)
10.4.5 Data address definition
The address definition of the communication data in this part is to control the running of the inverter
and get the state information and relative function parameters of the inverter.
10.4.5.1 The rules of parameter address of the function codes
The parameter address occupies 2 bytes with the fact that the high bit is in the front and the low bit is
in the behind. The ranges of high and low byte are: high byte—00–ffH; low byte—00–ffH. The high
byte is the group number before the radix point of the function code and the low byte is the number
after the radix point. But both the high byte and the low byte should be changed into hex. For example
P05.06, the group number before the radix point of the function code is 05, then the high bit of the
parameter is 05, the number after the radix point 06, then the low bit of the parameter is 06, then the
function code address is 0506H and the parameter address of P10.01 is 0A01H.
