The slave uses functional code fields and fault addresses to indicate it is a normal response or some
error occurs (named as objection response). For normal responses, the slave shows corresponding
function codes, digital address or sub-function codes as the response. For objection responses, the slave
returns a code which equals the normal code, but the first byte is logic 1.
For example: when the master sends a message to the slave, requiring it to read a group of address data
of the inverter function codes, there will be following function codes:
For normal responses, the slave responds the same codes, while for objection responses, it will return:
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
Some of the operation addresses are invalid or not allowed to access.
Especially the combination of the register and the transmitting bytes are
invalid.
When there are invalid data in the message framed received by slave.
Note: This error code does not indicate the data value to write exceed the
range, but indicate the message frame is an illegal frame.
The parameter setting in parameter writing is invalid. For example, the function
input terminal cannot be set repeatedly.
The password written to the password check address is not same as the
password set by P7.00.
In the frame message sent by the upper computer, the length of the digital
frame is incorrect or the counting of CRC check bit in RTU is different from the
lower computer.
It only happens in write command
The modified parameter in the writing of the upper computer cannot be
modified during running.
When the upper computer is writing or reading and the user password is set
without password unlocking, it will report that the system is locked.
