7.3.4 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.
7.3.4.1 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 t he function code address is
0505H and the parameter address of P10.01 is 0A01H.
Note: PE group is the factory parameter which can not be read or changed. Some parameters can not be
changed when the inverter is in the running state and some parameters can not be changed in any state.
The setting range, unit and relative instructions should be paid attention to when modifying the function
code parameters.
Besides, EEPROM is stocked frequently, which may shorten the usage time of EEPROM. For users, some
functions are not necessary to be stocked on the communication mode. The needs can be met on by
