12.2.10 Error code [D8156]

This device stores the error code when an error is caused in communication with an inverter by an EXTR
instruction.
1. Detailed contents
D8156 stores one of the following error codes when an error is caused in communication with an inverter by
the EXTR instruction.
Error
code
0 Normal end (no error)
1 Inverter did not give response.
Timeout error. This code interlocks with M8156. Sending from inverter was aborted
2
midway through.
3 An unspecified station gave response.
4 The sum of data sent back by the inverter did not match.
In writing or reading a parameter, an improper parameter number was specified. At
5
this time, the error code K6702 is set to D8067.
Because the port is being used for another communication, it cannot be used for
6
communication with the inverter. At this time, the error code K6762 is set to D8067.
A value outside the allowable range is set to the station number.
7
At this time, error code (K6706) is set to D8067.
Inverter sent the error code H0. Computer NAK error.
256 An error was included in the transfer request data from the computer beyond the
allowable number of retries.
Inverter sent the error code H1. Parity error.
257
The contents are different from the specified parity.
Inverter sent the error code H2. Sum check error.
258 The sum check code in the computer is different from the sum value calculated from
the data received by inverter.
Inverter sent the error code H3. Protocol error.
Syntax error is included in the data received by the inverter, and the receiving of
259
data has not been completed within the specified time, or CR/LF does not agree
with the parameters.
Inverter sent the error code H4. Framing error.
260
The stop bit length is different from the initial set value.
Inverter sent the error code H5. Overrun error.
261 Before receiving the completed data in the inverter, the computer sent the next set
of data.
Inverter sent the error code H6.
262
Not defined currently in inverter.
