2, if it is set to 3, because the number is
beyond the range, the inverter will return fault response message as below:

Abnormal response code 86H means the abnormal response to writing command 06H; the fault code
is 04H. In the table above, its name is operation failed and its meaning is that the parameter setting in
parameter writing is invalid.
10.4.8 Example of writing and reading
Refer to 10.4.1 and 10.4.2 for the command format.
10.4.8.1 Example of reading command 03H
Read the state word 1 of the inverter with the address of 01H (refer to table 1). From the table 1, the
parameter address of the state word 1 of the inverter is 2100H.
