7.4 The definition of data address

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.
7.4.1 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 range 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 P05.05, 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 05, then the low bit of the parameter is 05, then the function code address is 0505H and the
parameter address of P10.01 is 0A01H.
