According to the returned data, 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.

According to the number of decimals, the fieldbus scale of the "Max. output frequency" (P00.03) is
100. Multiply 100 Hz by 100. The value 10000 is obtained, and it is 2710H in the hexadecimal form.
The command transmitted by the master is as follows:
