0 0 0 0 0 0 1 1 (Hex 03H)
For normal responses, the slave responds the same codes, while for objection responses, it will
return:
1 0 0 0 0 0 1 1 (Hex 83H)
Besides the function codes modification for the objection fault, the slave will respond a byte of
abnormal code which defines the error reason. When the master receives the response for the
objection, in a typical processing, it will send the message again or modify the corresponding order.
For example, set the
“running command channel” of the inverter (P00.01, parameter address is
0001H) with the address of 01H to 03, the command is as following:
But the setting range of
“running command channel” is 0~2, 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.
10.4.7 Example of writing and reading
Refer to 11.4.1 and 11.4.2 for the command format.
10.4.7.1 Example of reading command 03H
Example 1: 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.
The command sent to the inverter:
If the response message is as below:
The data content is 0003H. From the table 1, the inverter stops.
Example 2: Watch
“the current fault type” to “the previous 5 times fault type” of the inverter through
