Goodrive350-19 series VFD
01
VFD
address
Assume that the following response is returned:
01
VFD
address
The data content returned by the VFD is 0003H, which indicates that the VFD is in the stopped state.
Example 2: View information about the VFD whose address is 03H, including "Type of current fault"
(P07.27) to "Type of last but four fault" (P07.32) of which the parameter addresses are 071BH to
0720H (contiguous 6 parameter addresses starting from 071BH).
The command transmitted to the VFD is as follows:
03
VFD

From the returned data, we can see that all the fault types are 0023H, that is, 35 in the decimal form,
which means the maladjustment fault (STo)
10.4.8.2 Write command 06H examples
Example 1: Set the VFD whose address is 03H to be forward running. Refer to the table of other
function parameters, the address of "Communication-based control command" is 2000H, and 0001H
indicates forward running, as shown in the following figure.
