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. For example, the function input terminal can not be set repeatedly.
7.3.7 Example of writing and reading
Refer to 7.3.4.1 and 7.3.4.2 for the command format.
7.3.7.1 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.
The command sent to the inverter:
The response message is as below:
