C.2.6 Error messages
Table C-2 Code and definition for fault message response
The command code received by the upper computer is not allowed to
be executed. The possible causes are as follows:
1. The function code is applicable only on new devices and is not
implemented on this device.
2. The slave is in faulty state when processing this request.
For the inverter, the data address in the request of the upper
computer is not allowed. In particular, the combination of the register
address and the number of the to-be-sent bytes is invalid.
The received data domain contains a value that is not allowed. The
value indicates the error of the remaining structure in the combined
request.
Note: It does not mean that the data item submitted for storage in the
register includes a value unexpected by the program.
The parameter is set to an invalid value in the write operation. For
example, a function input terminal cannot be set repeatedly.
The password entered in the password verification address is
different from that is specified by P07.00.
The data frame sent from the upper computer is incorrect in the
length, or in the RTU format, the value of the CRC check bit is
inconsistent with the CRC value calculated by the lower computer.
The parameter to be modified in the write operation of the upper
computer is a read-only parameter.
