Goodrive10 Series Mini VFD Communication protocol
-93-
7.3.3 Command code 08H, diagnosis
Sub-function code description:
Return data based on query requests
For example, to query about the circuit detection information about the VFD whose address
is 01H, the query and return strings are the same, and the formats are described in the
following tables.
7.3.4 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.
7.3.4.1 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.
Note:
P29 group is the factory parameter which cannot be read or changed. Some
parameters cannot be changed when the VFD is in the running state and some
parameters cannot be changed in any state. The setting range, unit and related
