Goodrive3000 series medium voltage VFD
01
address
Assume that the following response is returned:
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 "Present fault type" (P07.27) to "5th-last
fault type" (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:
Assume that the following response is returned:
03 03 0C 00 23 00 23 00 23 00 23
VFD Read
address command
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).
8.4.7.2 Example of writing command 06H
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 table.
Function
Communication-base

The command transmitted from the master is as follows:
If the operation is successful, the following response is returned (same as the command sent from the master):
