10.4.5 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.
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 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 P05.06, 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
05, then the low bit of the parameter is 06, then t he function code address is 0506H and the
parameter address of P10.01 is 0A01H.
