7.4 Data address definition
This section describes the address definition of communication data. The addresses are used
for controlling the running, obtaining the status information, and setting function parameters of
the VFD.
7.4.1 Function code address format rules
The parameter address occupies 2 bytes with the fact that the MSB is in the front and the LSB
is in the behind. The range of 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 changed 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 of the parameter is 05, then
the function code address is 0505H and the parameter address of P10.01 is 0A01H.
