7.4 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.
7.4.1 Function code address format rules
The parameter address occupies 2 bytes with the most significant byte (MSB) in the front and
the least significant byte (LSB) in the behind. The ranges of the MSB and LSB are:
MSB—00–ffH; LSB—00–ffH. The MSB is the group number before the radix point of the
function code and the LSB is the number after the radix point, but both the MSB and the LSB
should be converted into hex. For example, P05.05, the group number before the radix point
of the function code is 05, then the MSB of the parameter is 05, the number after the radix
point 05, then the LSB the parameter is 05, then the function code address is 0505H and the
parameter address of P10.01 is 0A01H.

Note: P29 group is the factory parameter which cannot be read or changed. Some parameters
cannot be changed when the inverter is in the running state and some parameters cannot be
changed in any state. The setting range, unit and relative instructions should be paid attention
to when modifying the function code parameters.
